  1. Might be worth mentioning the Quadro M2000 in the comparison is 2x the price of the WX3100... Quadro P600 is probably a more appropriate competitor at this price point.
  2. The only vendor I can find with a listing is Span, and they don't show even a price at the moment. ST12000NM0007 (SATA, 512e) version and ST12000NM0047 (SATA, 4Kn)... didn't check for the rest.
  3. Technological differences or actual performance? Reviews cover both areas fairly well. What sort of use? If this is typical or even enthusiast desktop use, you're not going to see a difference in actual use short of timing everything with a stopwatch for benchmarks...
  4. Spec sheet in the article says it's preconfigured for RAID0 and preformatted as exFAT. As long as your OS supports exFAT I don't see why not.
  5. Hmm. Well, graphics in the article with a few more cards would be nice if nothing else?
  6. Is there a comparison database or anything with all the SD/microSD cards you guys have tested anywhere? Just curious if the 128GB one got tested and I'm not seeing the review...
  7. SMR performance has gotten more than a few tweaks as time as gone on, I think Anandtech's got a more recent review than the original Archive 8TB that had better performance. I'd be curious how that handled RAID use. As interesting as a possible SMR + PMR for rebuilds could be, I don't think long-term that's going to be as useful because long-term, it sounds like PMR drives will go away. (also, as a nitpick, I'd much rather see RAID6 testing than RAID5, especially given that the UBER's start to catch up to you when you're taking volumes this big...)
  8. I doubt you'd see any perceptible performance difference, but if you need the capacity, then go for it.
  9. What exactly are you doing with this hardware? How much performance did you need-- or at least, what applications are you running? What's your budget? You'll need to provide more detailed information for useful feedback. FWIW this should probably be posted in SMB/Enterprise Storage.
  10. Take the drive out and put it in another computer, and see if it comes up. File system errors may mean you're SOL, or it may mean you can pull 99% off, there's insufficient information to say.
  11. Just to complicate things, Seagate has their own helium drive design on the way (if not already here) too. Don't think it has hit retail yet tho. Never seen a review listed in watts per TB, but I suppose that's a valid metric.
  12. Highest performance is going to be RAID0, but obviously there's no redundancy with that. RAID10 plus a hot spare maybe? Not sure how fast that card gets, it's an LSI 2208 chip so I don't think the controller would bottleneck performance in such a setup.
  13. What do you need? Redundancy/high availablity? High performance? How much total capacity and how budget did you have? What controller is this-- you may end up limited by the controller in some cases, too...
  14. No idea if it will do NVMe, but there's a couple of external PCI-e GPU enclosures out there that should work in theory. You'd probably need a M.2 to PCI-e adapter card to fit inside the enclosure, and I don't know if any or all need external power.
  15. Software RAID is usually done by the CPU on your system via the OS. I don't think Windows 7 does any sort of useful software RAID. The chipset RAID on your motherboard is probably the last thing you'd want to use, since you'd be tied to the AMD 990FX chipset-- if your motherboard ever died you'd be screwed. However, the chipset RAID on your motherboard would pass through just fine to Windows 7. The manual is available at the link you provided: http://www.gigabyte.com/Motherboard/GA-990FXA-UD7-rev-1x#support-manual You can use Velcoraptor's in RAID, but as WD says, strictly speaking it is not a configuration they support due to lack of RAID-friendly firmware and hardware specifics on the drives. Intel 520 series SSD's should work fine in RAID as well. However note that the Intel 520 Series is pretty old, and especially at the 120GB capacity point, they are pretty slow as the 120GB capacity point has insufficient parallelism to take full advantage of the SSD controller's capabilities. A single Intel 520 Series 240GB or pretty much any modern SSD would be an option worth considering. Ditto for your Velociraptors-- a modern 1TB/platter 7200rpm harddisk is probably faster if that is an option for you.
  16. The controllers do exist, such as: https://www.broadcom.com/products/pcie-switches-bridges/usb-pci/usb-controllers/usb3380 (assuming I'm reading the spec sheet right-- although that one doesn't say anything about supporting NVMe...) However I haven't looked for such a product... If your system supports Thunderbolt, that might be easier, since TB carries PCI-e natively...
  17. svchost is just a generic starting process -- the DLL's actually run are linked off it, can you download ProcessExplorer or some other diagnostic tools to determine what processes are actually being run? https://en.wikipedia.org/wiki/Svchost.exe
  18. Out of curiosity, which retailer were they from? I generally don't worry much about manufacturer date on drives, but "new" "old" stock that old is unusual.
  19. I think those are external from the model? I'm not 100% sure, but if they're external they might work-- I don't think the optical drive bay in the SFF is deep enough to fit an internal one (it might be, but I haven't checked). Either was as Kevin said you'll need a SAS PCI-e controller card. Half-height since that's all the SFF chassis allows.
  20. 3ware

    If some show up I would think you should be on WRT firmware compatibility, but RAID can be more fickle than anything... unfortunately I don't have much specific experience with the 9550SX, mostly the one before (9500, I think it was). As Brian said for anything that old you might be SOL...
  21. The average user, even a power user, won't notice the difference between PCI-e and SATA SSD's. I'd save your money and buy whatever's the best value you can find for the size you need. Sandisk X400, Crucial MX300, whatever... you can buy 'em in M.2 form factor so not sure why you're worried about cables? (M.2 form factor supports both PCI-e and SATA, just need to see what your motherboard supports- very likely it's both PCI-e and SATA) If you don't care about write performance then why worry about it? Also a good TLC NAND equipped SSD under even most power users' workload is not likely to exhaust its pseudo-SLC cache, and hence you will never notice the performance drop because you won't ever get that far. If you're reading benchmarks at Anandtech or Storagereview or whatnot where they do show the performance hit, well, it's true, but how often are you ever going to push that many sustained I/Os?
  22. Glad someone's giving Samsung competition.
  23. Does your backplane actually have a SAS expander chip in it? Or is it just a backplane? If the backplane is just a plain backplane then using the correct cables should work. If your backplane actually has a SAS expander chip in it, then you would need to make sure your new HBA is compatible with the SAS expander chip in the backplane, and you would be limited by connection speeds supported by the backplane's SAS expander.
  24. Or thousands. My last quote from OnTrack to recover, I think it was 20GB off a failed drive like this, was something like $1800...
  25. Dropped it means crashed heads... you're SOL. If you plan to send it for professional recovery do NOT open it. You're only risking further damage to the drive to zero additional benefit.
