I don't know when exactly their clock resets, but I just got the new Magician from Samsung after being blocked from it eight hours ago. Was surprised to see improvement in the graphs immediately, because there was no 'rewriting all data' stage during the firmware upgrade. The first 30GB on the disk (presumably the entire Windows install) used to drop to around 100MB/s (even after the C firmware) and now it sort of wobbles a bit between 250 and 300. Fingers crossed it sticks this time! e: In an hour of using the computer regularly, average went up to around 330, which is more or less in line with the rest of the drive. Gonna let the thing idle a bit, see where this is going. Flipperwaldt fucked around with this message at 01:26 on Apr 26, 2015 |

Mine is just over 400MB/s across the entire disk now. Was actually fine on the C firmware - I did see the same drops reappear a while after running the performance restoration tool but they didn't come back after forcing a rewrite of the entire thing with diskfresh

Installed the 840 Evo update and ran the Advanced Performance Optimization thing, which is exactly the same as the old "performance restoration tool". Considering Avulsion's graph I would not recommend running it manually, as it more or less locks up your computer for its duration. Ignore the huge spike.

I think the price per GB is low enough now that I'm considering buying a couple 850 evos to throw in my little NAS enclosure, anything to worry about with read heavy workloads on SSDs over SMB or am I good to go?

Is there a tool I can use to secure erase on a Mac? My macs right now for some reason aren't able to boot Parted Magic.

Sorry for asking a question I'm sure comes up a lot, but the OP was last updated half a year ago: I'm on the market for a SSD. Is the 840 Evo still the drive of choice? Did they fix the sluggish old data bug mentioned in the OP? Do they come in 7mm and 9mm thicknesses (I'm not sure what one I need yet)?

840's are good. 850's are better if they can be had for a close price.

I'll give it a week just in case then update my 840 EVO's firmware. It's not worth replacing the SSD in this machine when I'm going to do a completely new build next year and the 840 EVO will either be an extra drive for games or I might migrate my server's boot drive onto it.Pryor on Fire posted:I think the price per GB is low enough now that I'm considering buying a couple 850 evos to throw in my little NAS enclosure, anything to worry about with read heavy workloads on SSDs over SMB or am I good to go? SSDs have no real problem with reads. It's only writes that SSDs have limits on, and only when you get into truly obscene numbers. I would, however, question whether you're going to get any real benefit from it. Any decent RAID5/6 or equivalent will saturate a gigabit network on reads very easily, assuming you don't run into stupid samba bottlenecks first, samba is terrible. If you're doing a lot of random operations on them it might make sense, but you're already losing a fair bit of latency to the network. It should be a lot faster on writes and, especially if your array is very large, the rebuilds will be faster, if that's a concern for you.

RAID has never worked properly for me over the decades, I don't even bother anymore. Don't need a ton of capacity or speed just want silent SSDs next to the TV and I can waste money so why not.

Neighbours are present but there are a lot of walls and a large gap between the houses. Is liking a silent computer weird? The drives weren't loud normally, but anyone who has use greens knows that whenever they spin up from idle they make a VERY high pitched loud whining noise for a couple seconds. I wear headphones but they are very open backed Audio Technicas that let all the sound in.

I guess the technology is more efficient to manufacture or whatever? Well, I'm not going to do this as much justice as Anandtech would, but here's my understanding of why it's better and cheaper at the same time. Samsung built the 840 EVO on 19nm technology, which is still very new and in demand. The 850 EVO NAND is made using 3D layering technology with the old 32nm process. This is a much older process that isn't in as much demand so they can accept lower margins on what they build with it. Yet the ability to stack the NAND 32 layers deep gives them higher bit density on the wafer than the 840 EVO. Plus, their 32nm yield has to be a lot better than 19nm at this point. That covers the cheaper. The better has to do with the fact that a feature at 32nm has roughly 3-4x more area to store the charge, so a few electrons leaking of a cell out here and there won't dramatically affect your ability to distinguish between the 8 charge levels programmed into the cell when using it as TLC. Oh, and the controller is probably more efficient as Samsung iterates on their design. Edit: 32 layers, not 24. Peanut3141 fucked around with this message at 03:36 on Apr 27, 2015 |

Speaking of TRIM... I have it enabled on my Intel 730 boot, but TrimCheck is saying my F: drive, a 750GB 840 EVO, *doesn't* have it enabled. How would I go about enabling it, or will I just have to manually TRIM the drive every so often? I should note that thanks to seeing a bit of access time and benchmark anomalies, I updated the new 'D' firmware, so technically the drive should be TRIMing itself during idle times.

Yep - it's a Z68 board, and I've got the Marvell controller completely disabled (and I just double-checked that I'm in AHCI mode in BIOS).

I tossed an 1tb 850 Evo SSD into a Proliant server and installed CentOS7 and it was perfectly fine. Then I added a second identical drive, turned both drives into a Raid 1, and reinstalled CentOS7. Everything seems perfectly fine, except the drive activity lights were going completely rapid-fire bonkers for 6 hours straight while the machine was idle, until I finally shut it down. Is that normal or is there some kind of feedback loop that is causing a lot of write cycles? P410 raid controller.
