  1. Were the initial scans on the affected drive still trying to finish? I know we've encountered that a few times from customers-- the initial scan/initial index/whatever was still running before the customer pushed the unit into production....
  2. Under what circumstances? Things like data retention are extremely temperature dependent. Hence why the NAND spec itself is not that important, the environment and application it's going to be used in is hugely important. Shows a massive difference in the duration spec'ed for data retention-- the high temperature test is 13 hours at 85C, the low temperature test is 500 hours at 25C (note that that's just the testing, not the actual spec'ed retention of the NAND). " The JEDEC specification for data retention tells us that for enterprise storage devices, data retention at the end of the service life shall be at least three months (stored at 40°C). For SSDs in the client computing market, data retention shall be at least one year after the drive’s service life (assuming it’s stored at 30°C). " Shows 0C to +70C.
  3. That would be up to the aerospace and defense application vendor designing the spec. I think you'd want to ask them, not the SSD maker...:P
  4. Does defragmenting the drive help?
  5. Toshiba has some SSHD's too, but I think they're also 5400rpm. You're probably SOL unless you want an old model like the Momentus XT, and given the areal density improvements in newer drives, a newer 5400rpm drive is almost certainly faster than an older 7200rpm drive with lower areal density. Toshiba product page for Toshiba's SSHD's: SR benchmarks of an old (circa 2013) Seagate Momentus Thin vs. the even older Momentus XT... note in actual application traces, the Momentus Thin is faster... the newest one is the Seagate FireCuda, but I'm not seeing any reviews yet... The current (circa 2015) Seagate Laptop SSHD 1TB smokes the 750GB one in desktop benchmarks, but I think it's now technically one generation behind the Seagate FireCuda 2.5" line.
  6. Part numbers are in one of the tabs on that page. Performance differences on modern 1TB/platter+ drives are pretty modest, I wouldn't stress too much if it's a 5400rpm vs a 7200rpm drive unless lots of small files are involved.
  7. You haven't given nearly enough work-load-specific information... but 99% of desktop won't see the difference. It's safe to say you're in that 99%.
  8. Legacy is not UEFI. You should have seen both a UEFI and a Legacy option in the system boot menu. Heck I just setup a Z440 a few months ago, unfortunately I no longer have access to that box so I can't take any screenshots for you.
  9. We copy easily a few PB of data per year between various computers with various brands and sizes of external drives without any errors that we've noticed. Given typical rated error rates of 1*10^14 you shouldn't be seeing errors anywhere nearly this often-- maybe one every few TB. What programs are you using to copy? If you think about it, if you're getting errors nearly as often as you are, you should be seeing system instability frequently as well...?
  10. Is there any plan to do any thermal throttling testing of M.2 SSD's?
  11. 5TB in a single 2.5" external means it could replace quite a few of existing (mostly older) 3.5" 5TB and smaller external disks we have in use now. Tempting, depending on performance.,32860.html Says it's air and PMR...?? (awesome if it is, means more room for helium...!)
  12. I'd go hit HP, Dell, Cisco, etc. websites too to see what they price. A reseller normally gets a big chunk off, but it's usually still not cheap. Have you talked to other resellers?
  13. The controller manages the flash, I doubt it's even visible to the UEFI, so probably not? WD did a combo SSD + HDD at some point a while back but I don't think it sold very well. WD Black2 Dual Drive, I think it was.
