Aquila posted:I am speccing out some database servers that will be running SSD raid arrays and wanted see if there are any models I should be considering but have missed. My initial choices were either Intel DC S3700 or 520 ssds, but both are mostly unavailable, at least in 400GB+ sizes. The Samsung 840pro appears to not perform well at all in raids, leaving Sandforce drives as my only option it seems. I've already purchased some Sandisk Extreme 480GB ssds for testing and will be getting some Mushkin Chronos Deluxe in my next order. Reliability and consistency are my main concerns, followed by price and performance. What kind of write loads are you expecting? Because unless it's no more ~10 GB per day or less, you will be replacing consumer drives very quickly (without TRIM, the write amplification will be a lot higher, so 10 GB of host writes could easily become 40 overprovisioned, or 100 on a full drive). With drives as big as you're looking for, I kinda doubt that your writes will be that small. The Micron P400m (not P400e, make sure the m is there) is Micron/Crucial's DC S3700 competitor. Might want to look at that. Newegg has the 400 GB ones for $600 each. But the DC S3700 is the better drive.

I have an Early 2011 13" MBP with 8g memory. I'm looking to replace my HD with a 480g SSD drive. Going off the op I've narrowed it down to 2 and am wondering which would be the best to put in there as the only HD in my laptop. Option 1: Mushkin Enhanced Chronos Deluxe 480g 1.8" SATA III http://www.newegg.com/Product/Produ...N82E16820226393 Option 2: OWC Aura Pro 480GB 1.8" SATA I http://eshop.macsales.com/item/OWC/SSDAP81480/ Would both of these work and is there one that is preferred over the other for MBP's? Do I need to purchase anything else with either drive so it fits/connects properly?

Personally I'd get a Samsung because they have the kind of controllers that Apple themselves use in many models. I know trim blah blah, for me a solid controller is worth more than a small amount of performance I probably wont notice.

Pretty sure your looking at the same SSD there, OWC doesn't make SSDs, they just rebrand other SSDs and they have used Mushkin before. The downside to going OWC is that it is more difficult to upgrade to the latest firmware.

So considering my laptop only supports sata-300 internally i might as well upgrade to the 512GB Samsung 840 non-pro instead of the pro since according to the OP the larger non-pro models are fine and i can't make use of the extra performance anyway? Or am i missing other essential differences? I'd mostly use it for database activity writing shitloads of temporary table data.

And it has poor write consistency under that kind of load, even better! You should probably get a big Sandforce drive instead.

It's not reliability issues in the sense of bugs, it's that the NAND burns out way faster than normal, and that's entirely intended (use the junk NAND for a cheap drive). With larger drives, there's just so much NAND that it still last a while regardless - at least, for normal desktop workloads.

The downside to going OWC is that it is more difficult to upgrade to the latest firmware. OWC boasts that their SSDs are assembled in the USA, and they're made out of blue aluminum, as well. I haven't read anything about them using rebranded drives. And regarding updates, even though the OWC software is poo poo (you can just use a generic SandForce updater on their drives), they are up to date with firmware. If anything, the highly-regarded SanDisk is one that lags on firmware updates. Mushkin: 5.0.7 OWC: 5.0.7 SanDisk 5.0.4 (released as "R211")

The Micron P400m looks interesting, I had quickly checked http://thessdreview.com/ssd-database/ and thought all the enterprise Micron drives use the 9174 controller and haven't been too impressed with single Crucial (Micron) consumer SSDs in database test roles. Write endurance is another thing that's got me concerned. I can't hold up the project to get the SSDs of my choice. I would estimate that we're at less than 50GB a day on average (on a 1TB usable raid 10 array of 8 drives). For various frustrating reasons I cannot get smart info for the SSD's (Intel 320's I believe) my host is using on the DB's we're currently leasing. In fact, if someone could provide me with a method to get smart info for ssd's on an Areca 1882 controller in linux I will buy you a forum upgrade of your choice.

Sure, why wouldn't you be able to? If you mean "can I mount it in the case," some cases don't offer 2.5" mounts, it's true, but  have no moving parts. They're perfectly happy danging from the cables, duct-taped to the case wall, whatever.

I got an old Dell Dimension E520 I need to keep alive a bit longer until Haswell comes around, and I don't feel like paying extra for an SSD when I buy a new laptop anyways. I'll probably pick it up.

Alfalfa posted:I was just going off the names listed in the op and they all popped up 1.8" I ran into this same problem and figured out by comparing Mushkin part numbers that the "Mushkin Enhanced" "Chronos Deluxe" (first part is make, second is model) is called the "Mushkin Enhanced" "Deluxe" on Newegg. http://www.newegg.com/Product/Produ...N82E16820226255 Look for the DX at the end of the part number, DX7 for 7mm. I'm ordering one now for testing and will report if it's not what I'm expecting.

With larger drives, there's just so much NAND that it still last a while regardless - at least, for normal desktop workloads. It's not that the NAND in the non-Pro 840 is "junk" per se, it's that the 840 Pro uses 2-bit per cell MLC while the non-Pro 840 uses 3-bit per cell TLC NAND. The trade-off is that the non-Pro needs less silicon for a given capacity in exchange for lower endurance and a lower price.

T-Shaped posted:Ordered that Sandisk Extreme from yesterday, but didn't see any migration guide in the OP. Alternately, cut your system drive's used space down to around 80% the capacity of the SSD. Then back up a system image with Windows Backup and restore it with a Windows install disk. This only really works with a backup drive (which you should have anyway), although admittedly I never tried backing up to the drive Windows was already on.

1) Read the OP. 2) The only motherboards that have issues with SSDs (more accurately with SATA 6Gbit/sec devices) are those with nVidia chipsets, which haven't been sold for a while now. 3) 240GB. 250/256 don't have built-in overprovisioning, and while you can get a similar effect by not partitioning the entire drive it's not quite as effective a bulwark against the drive's degradation. (Or at all on a drive that's been previously full-partitioned, if you don't take certain steps involving Secure Erase - which is a bad idea if you haven't backed up your SSD.) 4) Seriously, there's some brand/firmware issues that are important to discuss and they're covered in the OP. Go back and read it.
