Bad(ish) news about my 960 Evo and Asus X99 motherboard. It indeed disappears on warm reboots, but the motherboard also automatically reboots when it can't find a boot drive and on the second reboot it's worked every single time. It's not the worst thing in the world considering it's never failed to boot after a second try, but with the newest motherboard bios and drive firmware it still doesn't seem 100% reliable. For now it means reboots take like a minute longer for the missing boot device error to time out (or me to remember and reboot it manually) and I'll try messing more with it later. Besides that performance is fine, 3GB/s reads 2GB/s writes, and it never fails once it's booted. I know it's not a great report back, but I hate posts where people describe a problem and then disappear with no resolution. Edit: (Hopefully) Fixed it! I disabled the Compatibility Support Module entirely, auto is no good, nor are any of the detailed settings for various components. Setting it to disabled seems to have fixed it, at least in my case. Hopefully that can help someone else in the future. craig588 fucked around with this message at 20:34 on May 3, 2017 |

I bought a second-hand laptop which, according to Crystaldiskinfo, contains a near-new Samsung 830 SSD but only 128GB. I've got a Samsung 840 EVO 256 GB SSD in my PC which is 3 years old, and has been used for roughly 16.000 hours but doesn't show any problems at all. I'll be selling the PC somewhere later this month and switching to the laptop for all my PC needs cause I'll be moving to a different country. Should I switch the 840 into my laptop for the extra GB's even though it's a much older part, or should I keep the 128GB one? If I could be fairly certain that my old SSD can still last a bunch of years I'd happily switch, but I only have experience with normal hdd's that crap out after 5-10 years. I checked some articles on SSD lifespan and they usually show calculations that end with some sort of heat-death of the universe timespan, but info from SSD's in google datacenters seems to suggest that age is more important than usage.

830 is MLC 2 bit NAND. 840 EVO is TLC 3 bit NAND. 840 EVO is twice as big so will last longer... as long as the controller doesn't poo poo the bed and those do have read consistency problems.

Thanks, didn't know about the MLC/TLC difference and that size influenced lifespan. Time to switch to the larger one and be more diligent with my backups I guess. As far as I can gather from the SMART data the 840 seems to be in good shape. That probably doesn't say anything about the controller but I'll risk it.

The controller doesn't refresh data correctly and files sitting for a long time can start to read extremely slowly. They kind of fixed this with a firmware update which also burns through more nand. The 830 is likely to have higher performance. Also I haven't had any 830s die on me at all. I have had 4 84O evo and pros die on me. :/

Aw bugger that sounds a lot more serious than I thought it would be. Well, and a bit better cause I kept thinking the 830 wasn't that great because I stupidly associated it with the SSD it originally seems to have replaced in the laptop, an mSATA Samsung PM851. Then I'll just live with 128GB till I decide to replace it with a new drive. Thanks for the advice.

This is mostly academic. But yeah if the 128 hasn't been used much, probably use that drive.

If that is the case, it's not a remarkable deal by any means - as it would be more or less the same drive as the mydigitalSSD BPX and I think the WD Black if I'm not mistaken, both have the same capacity around that same price point.

I don't even know if the itty-bitty m.2 Optane stick even fits the niche of what is commonly understood to be a "consumer" system.  Maaaaaybe it can be included with a heavy caveat.

I would say the HGST Ultrastar SN series are worthy additions to the enterprise nvme section. They're just harder to find than the Intels. Samsung PM1725a too. For the Optane I don't know who would really need one that much. They're great for folks who need really cheap nvme pcie endpoints and don't care about capacity, though!

Different performance and not all M.2 slots do both.

Sandisk is being given the HGST treatment so expect the rest of their consumer drives to disappear and be replaced with identical ones with WD branding. WD Black is within "good enough" for nvme drives like the 600p is, faster than the 600p in most cases but obviously much less endurance

I guess that thing wasn't such an amazing deal, so nevermind - I'm still figuring out relative NVMe lines/classes. Seems like everything is fuzzier and less standardized than SATA's nice clear I/II/III, but maybe I just haven't figured out what keywords to look for yet.

Is there such a thing as M.2 PCIe SSDs that aren't also NVMe? I am trying to find a suitable SSD for a Dell Optiplex 7040 Micro and can't seem to find anything official that states that it can take NVMe drives.

Randomly checked the compatibility list on WD's website for their 512GB Black NVMe SSD and the 7040 Micro is listed, so I guess that answers that question.

Star War Sex Parrot posted:Yes. M.2 supports 3 different protocols: Legacy SATA, AHCI over PCIe, and NVMe over PCIe. I think one of the three supported protocols is USB3, and you can lump SATA and AHCI together, but that doesn't really change the answer.

My 840 Evo kind of died last weekend. The timing is interesting and the way it's died has me curious, expecially as I can't perform a secure erase. I had windows 10 installed with bitlocker. Running windows restore from a live usb couldn't fix it. I tried various sata controllers/pcs. Some get further than others. So the best I can do it to run a linux live setup, and I can access and read 2 boot partitions and one recovery partition. The main partition is unreadable even at the dd level. So the disks isn't completely lost but I can't seem to perform a secure erase. I've tried various tools, the samsung secure erase boot disk just says that it's not possible to secure erase the disk. hdparm can't perform a secure erase. More interestingly the hdparm tool get get the drive info but the security section about whether it is locked, etc is missing. Has anyone experienced or herd of anything like this before? Is it possible for bitlocker to enable hardware encryption at a partition level rather than disk level? Is there any reason I can read from partition from a disk but performing secure erase or factory reset is not possible?

Also you can't lump Legacy SATA and AHCI together. They're two distinct implementations: one goes over the SATA PHY and the other is AHCI over the PCIe PHY.

Unless you work for or know for sure you are a target of the NSA, CIA or FBI (or equivalent), you should stop worrying and responsibly recycle it as you would any electronics. Otherwise, pry off the lid and take a drill to the center of every chip you can see and then recycle it. There are no middle options.

IIRC Bitlocker has to work at partition level - that's why it creates a second (unencrypted) boot partition if you don't already have onw

Samsung has a secure erase utility worth trying. Most likely you will have to pull the power cable out of the SSD while booted with the secure erase utility, then plug back in. The drives are locked at boot up and pulling power fixes that for some reason.

Requiring the user to fiddle with the power plug while the system is powered on is a nice way to prevent just that from happening and I'm still amazed that viruses/malware targeting the BIOS haven't gotten back in vogue now that they're all flashable from within Windows.

A normal samsung drive would say under the security section that it is locked, etc. but this drive doesn't even display that info.Oh and windows or any windows recovery tools just locks up when the drive is connected.
