 Crucial lied, data diedThe bad news keeps on coming: Anandtech has revealed that the power-loss protection Crucial claimed was present in their M500-MX100 drives does not exist. The drives do have extra capacitors, but they don't store enough energy to allow the drive to save data that is in-flight if power is lost, which is normally what "power-loss protection" means. Hot news on Samsung SSD slowdown issueUpdate 09/26/14: A firmware update to fix the Samsung 840 Evo read performance slowdown bug is in QA now and will be released October 15th. More details are also expected soon. An issue has been confirmed with Samsung 840 and 840 Evo SSDs that causes a read performance slowdown for old data after approximately one month. Changing, moving, or otherwise re-writing the data (including the wear-leveling the drive does in the background) restores full performance, which is why this issue wasn't caught sooner. Samsung has acknowledged the issue and confirmed it will be fixed via a firmware update, which you can check for and apply via the Samsung Magician software when it is released. More technical details and an estimated release for the fix are expected early next week (of 09/22). This issue does not cause data loss or drive failures and does not affect the performance of new data. What SSD should I buy? On any SSD keep at least 20% free space or performance and lifespan will suffer. Don't run the "OS Optimization" wizard in the software that comes with Samsung drives, it does silly things that don't help like disable CPU power management.A quick note on capacity: Get at least a 240GB drive if you can afford it. Smaller drives are much worse values, don't leave much capacity left at all after Windows is installed, and don't perform as well as larger drives. Never buy drives smaller than 120GB as they are not reliable. Best for normal desktop users: Best for enthusiasts and workstations: The Samsung 850 Pro (128GB-1TB, about $.75 per GB) provides the high, consistent performance required for content creation and demanding enthusiasts. This is a high-endurance drive rated for at least 150TB of writes with a 10 year warranty, the warranty does not expire at a specific wear-level and you may expect around 5000 times the drive's capacity (so 640TB for a 128GB drive). Consider whether the premium over the 840 Evo is really worth it for you, especially if you could afford a larger Evo. Best for Macs: The Samsung 850 Pro is the best choice for Macs because it offers excellent performance consistency. The design of OSX makes it apparent and annoying when drives take varying amounts of time to complete operations, and the 850 Pro completes all operations quickly. Additionally, it can be difficult (or annoying) to enable TRIM on OSX, so it's important to select a drive like the 850 Pro that maintains its performance well when TRIM doesn't work. If you want a less expensive option or have an older Mac that can't justify such a high-end drive, look at the "Good for older machines" section below. Leave 20% unpartitioned space on the drive, see "Overprovisioning" below. Best for laptops: Samsung drives are the most energy-efficient, the 850 Pro uses the least energy of any drive but it probably wouldn't result in a noticeable battery life difference over the 840 Evo, so just get the Evo. Note that drives come in 9mm and 7mm thickness, thinner laptops tend to use 7mm, so buy the appropriate size for your laptop. If you need an mSATA drive, definitely get a Samsung 840 Evo. M.2 (formerly known as NGFF) is a new slot that replaces mSATA. It allows both SATA and the much faster PCI-Express connectivity, and the point is busting past the SATA600 speed limit. Unfortunately there are currently no good drive options for this new slot, but watch this space for news! PCI-Express/SATA-Express drives: Are not really a thing yet, but soon! We're waiting for consumer PCIe SSDs that supports NVMe. See "Interfaces Explained" below. Good for older machines: The Intel SSD 520/530 (120-480GB, 5 year warranty) use Sandforce controllers that work particularly well in old computers that don't support TRIM compared to other drives. A similar option is the PNY XLR8 Pro (120-480GB, 3 year warranty), which is cheaper but less reliable. There's also the PNY XLR8 (non-Pro), which is cheaper still but slower, usually not worth the downgrade. Get an Intel drive if you can afford it, the price difference is usually tiny. Leave 20% unpartitioned space on the drive, see "Overprovisioning" below. Cheap and not good: The Crucial MX100 (128GB-512GB, about $.40 per GB) is one of the cheapest drives on the market because it isn't very good. Crucial has a poor reputation due to buggy drives, mediocre reliability, and not honoring their warranty, but this drive is rather mature so they might finally have it figured out. Not a good choice for OSX due to poor performance consistency. This is a low-endurance drive with a 3 year warranty, or 72 TB of writes, whichever comes first. Ridiculously cheap and pretty bad: The PNY Optima (120GB-480GB, about $.33 per GB after rebate) is by-far the cheapest drive on the market thanks to some steep rebates, mostly because it sucks. Expect extremely poor, inconsistent performance (so awful for OSX), and low reliability. Consider it a gamble. This drive has a 3 year warranty with no information on endurance. Leave 20% unpartitioned space on the drive, see "Overprovisioning" below. BAD brands to avoid: (not an exhaustive list, any drive not recommended above is probably bad so ask if you have questions) * OCZ went bankrupt due to how awful their drives were and various anti-consumer practices, and was recently bought by Toshiba. New drives starting from the ARC 100 might be okay, but I'll believe it when I see real reliability statistics. AMD sells re-branded OCZ drives. * Kingston drives use low-quality memory on any models and pull bait-and-switch scams, secretly switching out for slower, lower-quality memory when drives get popular. * ADATA similarly uses lower-quality memory and has a lot of questionable products. * Plextor drives have poorly tuned firmware, they benchmark well but are slower in real-world usage. How to install your new SSD If your case doesn't have 2.5" bays you can either purchase a 2.5" to 3.5" bay adapter, or just leave the SSD resting in a drive bay dangling by the cable. They weigh very little and don't need to be supported against vibration. Fresh installation (recommended): (Optional: Verify the system can complete at least one full pass of Memtest86+ and update the motherboard BIOS.) Ensure the SATA controller is set to AHCI mode in the BIOS. Disconnect all other drives and connect the SSD. Many motherboards have SATA ports provided by chips from different vendors, consult the manual to confirm you are connecting the drive to a SATA port provided by the chipset, either Intel or AMD. Install Windows, then install the latest chipset drivers from the manufacturer's website (Intel or AMD), then the latest AHCI drivers from the manufacturer's website (Intel or AMD). Intel calls its AHCI drivers "Rapid Storage Technology" software. Image over from an existing drive: (Don't try to image over from a failing hard drive or you will copy corrupted files and thus the system problems.) (Optional: Verify the system can complete at least one full pass of Memtest86+ and update the motherboard BIOS.) First, install all available Windows Updates. Install the latest chipset drivers from the manufacturer's website (Intel or AMD), then the latest AHCI drivers from the manufacturer's website (Intel or AMD). Intel calls its AHCI drivers "Rapid Storage Technology" software. Run Disk Cleanup, use the "cleanup system files" option, check all boxes, and run the cleanup. Then run CCleaner free to remove any remaining junk you don't want. Finally, disable System Restore through Control Panel, System, System Protection. Next, connect the SSD. Many motherboards have SATA ports provided by chips from different vendors, consult the manual to confirm you are connecting the drive to a SATA port provided by the chipset, either Intel or AMD. You can perform the actual imaging using Macrium Reflect Free, the Samsung Migration software works well with Samsung drives too. Once complete, disconnect the old drive and ensure that the new one boots correctly. Run the Windows Experience Index rater (pre-Windows 8), and re-enable System Restore. Installation on older computers: (Recommended: Verify the system can complete at least one full pass of Memtest86+ and update the motherboard BIOS.) Machines older than about five years may not support the TRIM command, which prevents Windows from telling the SSD when files have been deleted, causing old files to invisibly build up over time and bogging down performance. This is not a problem on any system with an Intel Core i-series processor or AMD APU processor, and generally not a problem on motherboards with Intel 4-series and later chipsets, or AMD 700-series and later chipsets. To prevent loss of performance on older systems, "Overprovision" the drive by creating the system partition around 20% smaller than the size of the drive, and leaving the rest of the space unused. For example, if you have a 240GB drive, partition it as 200GB or so. This allows the drive to more efficiently manage data, improving performance and lifespan. Aside from this, follow the steps above, but a BIOS update and fresh installation is strongly recommended. How to maintain and use an SSD On Samsung drives, the first thing you should do after completing Windows and driver updates is install the latest Samsung Magician software from the Samsung website. If your drive does not have the latest firmware, update it then reboot. Finally, enable RAPID Mode and reboot. Do not run the OS Optimization feature, it makes stupid changes that don't help like disabling CPU power saving. You can fix the changes it made by checking the "Advanced" tab to make sure all of the features are enabled (the button should show "Deactivate"), and use the shortcuts there to set your Virtual Memory settings appropriately, set your Power Plan to "Balanced", and enable System Restore. The "Performance Optimization" wizard is fine to use, all this does is run a TRIM pass on your drive, the same as the Windows 8 Disk Defragmenter. On any drive, performance and lifespan both begin to suffer if the drive has less than 20% free space, because the drive writes data less efficiently. This gets worse the more the drive is filled and the longer it is run in this state. In some cases drives can even get stuck in a low-performance state that they do not recover from without being wiped, though this is uncommon on modern drives without serious abuse. On any drive you should periodically check with the manufacturer for firmware updates and apply them, though it may be smart to wait a bit after the release of a new firmware update to verify it doesn't introduce problems. It is critical for performance that you keep your pagefile on your SSD, the resulting writes are not an issue at all on modern drives. If you are concerned about drive capacity it is fine to manually set the pagefile to a smaller size, but do not disable it or move it to an HDD. I personally recommend keeping your Library folders (My Documents, My Pictures, My Music, etc) on your SSD to avoid waiting for spin-up time as Windows Explorer and other apps hit these folders, and just using shortcuts to folders on other drives if you have too much media. However, most people report not noticing any difference from moving these libraries to other drives. You should always install any programs that start with your system or that are frequently used to your SSD. While games are often so large and complex that load-time doesn't benefit much from SSDs, if you have a fast system overall there can be significant boosts. Games that stream-in a lot of data during gameplay such as ARMA and Payday 2 experience significant performance improvements from an SSD, but aside from these rare cases there is no benefit to framerates. Overprovisioning Overprovisioning means keeping some of the drive's capacity in reserve to prevent loss of performance over time. This is only necessary when you have conditions that prevent your drive's block management from working correctly, such as an older system without TRIM or a low-quality SSD with bad block management. To overprovision, create your partition around 20% smaller than the size of your drive when installing Windows. If you are overprovisioning, you do not need to keep an additional 20% free on your partition. This is not necessary on modern systems with TRIM and good SSDs, just keeping free space on your partition is fine. SSD Reliability SSDs from good brands like Intel and Samsung average failure rates below 0.5%, significantly better than the 2% per year average for hard drives. Mediocre drives tend to have failure rates around 1-2%, similar to harddrives. Low quality drives from brands like OCZ have failure rates from 5-10% or even higher, similar to old and worn-out harddrives. This vast difference is why we push good brands so hard in this thread. SSDs can die by suddenly disappearing with no warning, so you should keep good backups just like any other drives. If your drive stops appearing, boot the machine up and leave it in the BIOS for 30 minutes, this can revive it long enough to let you back up your data, and maybe even fix it by updating the firmware. Endurance Explained You will not wear out your SSD, don't worry about it. Unlike hard drives, the flash memory used in SSDs can be erased and rewritten a finite number of times before it wears out and stops holding data. On very early drives this was a concern, because it was possible to wear out some parts of the drive before others with concentrated writes, like with the pagefile. Modern drives (like the last 5 years) use "wear-leveling" to spread writes over the entire drive and prevent this from happening. The lowest-endurance drive on the market is the Samsung 840 Evo 120GB, which can be overwritten 1000 times, for a total of at least 120 TB written before it wears out. If you're averaging around 10GB/day written to the drive, typical for a desktop user, it will take 32 years to wear the drive out. Now, if you somehow manage to overwrite the entire drive every day it would be possible to wear it out in around three years, but buying a larger drive multiplies its endurance by the same factor as capacity, so a Samsung 840 Evo 500GB would last around 12 years at that same 120GB/day workload. Alternatively, the Samsung 850 Pro 128GB would last around 15+ years in the same workload because its memory has higher endurance, 5-6000 writes, with some samples reaching 8000. The following table shows estimated lifespans for the Samsung 840 Evo series in extreme (50GB/day) and ridiculous (100GB/day) workloads:  From Anandtech's Samsung 840 Evo review Data Fade Data written to flash memory fades with time. Standards say the data must be held for at least one year on a drive that's been worn to the manufacturer's limit, so in theory a new drive should hold data for several years. This isn't the kind of thing you have to worry about with a drive that gets used, just don't write data to an SSD (or flash drive, or SD card) and put it in a safe expecting the data to still be readable after a few years. It probably will be, but don't push your luck. Brand-specific Technologies The Samsung 840 Evo features a technology called TurboWrite, which reserves a small portion of the drive (3GB on the 120GB and 250GB models, more on larger models) to use as a higher-performance cache, particularly for handling the kind of small quick writes that the rest of the drive is slow at. This makes the 840 Evo, a value priced drive, perform like an expensive high-end drive when writing volumes of data around the size of the cache or smaller. Most of the time you're not writing more than 3GB at a time so you enjoy the full speed of the cache. This graph from the Anandtech Samsung 840 Evo review shows TurboWrite working, notice how performance is higher until the cache fills up. SanDisk uses a similar technology called nCache in their Ultra Plus, Extreme II, and Extreme Pro drives, though it caches less data so is less useful. The Samsung 840 Evo, Pro, and 850 Pro support a feature called RAPID, which uses system RAM to cache data and optimize the way it's written to the drive, drastically improving the drive's real-world performance. This was enhanced for all supported drives with the release of the Samsung 850 Pro, the new RAPID 2.0 improves its effects. Note that some benchmarks show a huge performance loss due to RAPID, this is actually because the drive is now so fast that the benchmark program records wrong results for how long it took to complete. RAPID is meant to improve real-world performance and doesn't have much benefit on trace-based benchmarks. RAPID is not supported on OEM drives like the Samsung XP941. Sandforce (and Sandforce 2 with an upcoming Sandforce 3) is a brand of SSD controller featured in some drives from manufacturers such as Intel, PNY, and Corsair. They used features like lossless data compression and efficient organization of written data to significantly reduce the total amount of data written to the drive, effectively improving both performance and endurance. Sandforce also had industry-leading error correction, in theory allowing for even further improved endurance and unmatched reliability for the time. In practice, some manufacturers like OCZ instead used this margin to try to get away with lower-quality memory than should ever have been used in SSDs, giving Sandforce something of an undeserved bad reputation. Another key benefit of Sandforce controllers was that they had no need for RAM chips because of internal caches, which reduced the total cost of drives. Interfaces Explained The interface is how your SSD connects to and talks to your system. For years this has been simple, all SSDs connect over Serial ATA 600MB/sec (SATA600) and use the Advanced Host Controller Interface (AHCI) command set. The world is changing! PCI-Express connectivity is the new hotness, because it replaces the old single 600MB/sec SATA link with multiple PCIe links running at 500MB/sec (PCIe 2.0) or 1GB/sec (PCIe 3.0). You can connect drives over PCI-Express using the new SATA-Express connector, which is basically two SATA cables (one for each link), by plugging a drive into the new M.2 slot (which also supports SATA for backwards compatibility, so not all drives that go in this slot are fast), or using a classic PCI-Express slot. Most motherboards deliver PCIe 2.0 to their SATA-Express and M.2 slots, so SATA-Express runs at 1GB/sec (2x500) and M.2 runs at 2GB/sec (4x500). NVMe (Non-Volatile Memory Express) is a new interface specification that replaces AHCI. It's designed to allow for much higher drive performance with lower CPU and system overhead, and is really the primary point of moving away from SATA. Diagnostic and Benchmarking Utilities Crystal Disk Info (Standard Edition, Portable zip doesn't have anime or ads) is the best diagnostic program for drives. Crystal Disk Mark (Portable Edition doesn't have anime or ads) is a good benchmark utility. Please don't post your benchmarks in this thread unless you need help, they quickly clog things up! The Samsung Magician software is also a good benchmark for Samsung drives, and compares your benchmarks to the baseline.

This allows them to achieve latencies comparable to what Hitachi was reporting with their PCM SSD, but presumably with much higher capacity and lower cost. It looks like it should be compatible with any standard memory controller, but you likely need customized BIOS support and I don't see how you could mix these with DRAM DIMMs.

SanDisk has released the Ultra II (120-960GB), the first drive using TLC memory from a company other than Samsung. This drive is very similar to the 840 Evo, combining SanDisk's 19nm TLC NAND with an SLC caching scheme they call nCache 2.0, similar to Samsung's TurboWrite. Pricing seems to be directly targeting the Crucial MX100, so it'll be very interesting to see how performance stacks up! SanDisk also has a better track record than Crucial both with reliability and not being jerks to consumers.

Sibling of TB posted:So the overprovision by 20% to increase the life and performance of the drive is only when TRIM is not enabled, and when it is it's fine to fill the thing up all the way? Because the impression I'm getting from this thread is that other than this post, everyone seems to be saying that you never want to go below 20% free space. Overprovisioning is when you make the partition smaller than the size of the drive. This is only necessary on systems without working TRIM or on SSDs with lovely block management.

Here's a similar comparison between the Intel SSD 530 240GB and Intel SSD 730 480GB, and the 530 is at a disadvantage because they are testing the larger model 730.

Cat Hatter posted:So this is bad and I should be replacing my wife's HDD (probably with a SSD) right? E: In case it is helpful to you or others, the SanDisk Ultra Plus 128GB for $59.99 currently holds the crown for "cheapest SSD on Newegg that is not godawful." It's kinda slow and not too good for old computers (without TRIM), and of course 128GB isn't much space at all even for casual use, but there are a lot of worse SSDs out there. The Crucial MX100 256GB is running a promo code down to $100 that unseats the PNY Optima as the cheapest 256GB SSD, which is good because despite being a kind of sucky drive the Optima is a VERY sucky drive so that is an improvement. With the Samsung 840 Evo 250GB on sale for <$120 I would still go with that since it is an actually good, reliable, fast drive from a good company.

goobernoodles posted:Thoughts? Is the performance increase of two 250gb ssd's in RAID-0 worth shooting myself in the foot a little bit with regards to future upgradability? Maybe I should just go for the 500gb and grab another in another year or so. I don't keep anything critical on these drives so the risk of losing data means jack poo poo to me. I keep the OS, games, photoshop, and lots of dirty, dirty torrents until I clean my act up and change the download directory. E: Edited the quick summary of the Crucial MX100 to "cheap and not good" and the PNY Optima to "Ridiculously cheap and pretty bad" to make it clearer. The only reason those drives are listed is because they are the least bad options at the lowest end of the market. Alereon fucked around with this message at 00:15 on Aug 26, 2014 |

Dick Fagballzson posted:NewEgg has the 480GB Intel 730 Series for $262. That seems like a pretty cheap price for something that's practically enterprise grade from everything I've read. I know you can get a 500GB EVO for that price any day of the week, but I don't think it's anywhere near the quality of the Intel drive. Any reason I shouldn't pull the trigger?

Welmu posted:The Asus Z97 VII Hero has a 2x M.2 slot. Is there a compelling reason to buy anything else than a 256GB 840 EVO / 850 for gaming and general usage? What are the odds of consumer-level M.2 drives being launched this year?

Dick Fagballzson posted:So if I can grab a 730 for the price of an EVO, that makes the most sense to me. I would agree that under normal circumstances with the 730 at its usual price, the EVO is a much better value. E: Power-loss protection is a benefit if that's something you care about, though if unexpected power losses are a thing you have to deal with I'd suggest a good UPS with true sine wave output, as power-loss protection on your SSD does not prevent data loss from writes that haven't been committed yet, and doesn't guarantee your filesystem won't be corrupted.

Anandtech has a PCIe SSD faceoff between the Samsung XP941 and OCZ RevoDrive 350. Huge takeaway: There are known drive-killing firmware bugs with the Samsung XP941, do not buy it. They're not intended for consumer sale and are unsupported for a reason. The OCZ drive sucks about as much as would be expected for 2-4 Sandforce drives in their RAID0-like setup. PCIe drives that support NVMe will be cool, but they are still a few months away.

AHCI drivers are not critical, if you can't get the AMD drivers to install the Windows-provided drivers will work and support TRIM. There is some loss of performance, but it's not huge.

Xenomorph posted:Uh, wouldn't the static wear-leveling negate the "issue" of having data sit on the same NAND? Some on that forum said that they did get some performance back after they ran a defrag on the drive or manually recopying the data (forcing it to new cells).

Raymn posted:I have a 256gb Crucial M4 that I haven't been real great about not keeping over 20% free though I typically don't go below 10% free, if ever. I saw in the OP that this can degrade performance, sometimes permanently without a drive wipe?, so I was curious how I would determine if my drive was suffering from this? Run a benchmark tool and compare to what the drive should be doing?

Raymn posted:I have Windows 7 but I assume the disk defragmenter would accomplish the same thing? EoRaptor posted:The more I think about this, the more I lean towards it being a translation table caching/indexing issue. The data is there in nvram, and all the nvram is rated to perform identically, but it seems like the step of translating LBA to pagetable location is taking much longer than it should.
