  1. I do. The speeds are amazing. I ran CrystalDiskMark, and I got the speeds they advertised on the product page (http://www.mydigitaldiscount.com/mydigitalssd-480gb-bpx-80mm-2280-m.2-pcie-gen3-x4-nvme-ssd-mdnvme80-bpx-0512/) - ~2700MB/s read and ~1400MB/s write. The price is very competitive too. As far as what Christopher mentioned - yes, it does get very hot when under load. VERY hot. It thermally throttles itself, but not as aggressively as I would like - I've seen its temperature climb above 90C. I did some research and it appears that basically all the nvme drives out there get similar
  2. It reads SMART data fine since it's just a JBOD controller. I'm not sure about drive spin-down - I keep all my drives on.
  3. It picks right back up. I'd attach all the disks first, make sure they're all being seen, and then install DrivePool. The point of doing the disks first just being that it's easier to troubleshoot disks not showing up while DrivePool isn't busy trying to examine the attached disks, in my opinion. If you already installed it, you can just disable the service and then later reenable it.
  4. I'm using DrivePool and Stablebit on my new 2016 server with no issues, Jason. I am using the beta versions of both, however. I've also run DP+Stablebit on several Win10 systems.
  5. My understanding was that Green drives park regardless of any power management settings set via software. That is, that their controllers do so independent of all the other power management stuff that's OS-controlled... I did check just now, though, and all my drives were either set to "APM -> Max Perf (no standby)" or the APM section was entirely grayed out (which seemed to be the case for a significant number of them).
  6. For those who aren't already aware of the issue - some drives (particularly WD "Green" drives) aggressively park their heads (every 8 seconds) to save power. This has caused serious longevity issues with those drives. I was switching disks over to a new server I built, and I noticed the load cycle count was quite high for a lot of drives. For some, I had already used the WDIDLE3 utility in the past, but not for all of them. Since using that tool is such a pain to do, I decided to just write a little script/service to keep the disks alive instead. Posting it here in case
  7. 1) Yes, 2016 is supported 2) Yes, that's not a problem. DP works at a file-level, so it isn't concerned with interfaces, block sizes, disk signatures, etc. 3) 42
  8. Unsafe Direct/IO didn't work, and none of the "specific methods" did either.
  9. Thanks! Sounds like everything should work fine, regardless of duplication settings then.
  10. When realtime duplication is disabled, and an already-duplicated file is updated, presumably this file is written to only one drive (out of, say, 2 it was duplicated onto) ... how does DrivePool later know which of the 2 now-different versions of the file to duplicate? I ask this because I'm writing a file auditing / change indexing / integrity-verifying program that utilizes a custom alternate data stream which is added to each file with miscellaneous tracking information. When that happens, the main data stream ($DATA) doesn't change, and I'm using special overrides to disable updating t
  11. I've switched my desktop over to Windows 10 on one of these: http://www.mydigitaldiscount.com/mydigitalssd-480gb-bpx-80mm-2280-m.2-pcie-gen3-x4-nvme-ssd-mdnvme80-bpx-0512/ CrystalDiskInfo shows the SMART status for the drive, but StableBit.Scanner_2.5.2.3103_BETA says "The on-disk SMART check is not accessible" The DirectIOTest results are attached. Thanks
  12. There's no need to have the disks mounted at all for DrivePool's purposes, so you can just go to diskmgmt.msc and remove the letters as far as it's concerned. For snapraid, though, maybe you could mount the disks as folders? http://wiki.covecube.com/StableBit_DrivePool_Q4822624
  13. Ah, gotcha. Backups are different than RAID. If you accidentally deleted everything with a stray command, or got hit with a ransomware virus, for instance, all your data would instantly be lost with RAID. RAID's purpose is only to keep systems up in the event of hardware failure. If a copy of your data is not sitting in another system, with versioning handled, then your data is supremely vulnerable. Also, "parity" is just something people say for short when referring to one type of RAID - RAID5 or RAID6 levels (or, in ZFS notation, "RAIDZ" or "RAIDZ2"). If you use DrivePool with 1 file dup
  14. When you add a drive to a pool, all that happens to the drive is that a folder named "PoolPart-<IDString>" is added to the root of the drive. You can then cut and paste content from the disk (or not) into that folder. What you put into that folder appears in the overall merged pool. If two matching files on different disks collide, they will both be added and the second/third/etc copy will just be utilized as duplicate copies. Yes, everything is still a plain file. All your DrivePool data on each disk just reside inside of the PoolPart folder on the disk. You should bac
  15. UPSs help, but power supplies still fail, and UPS units go bad as well. In a home lab/etc situation that's one thing, but domain controllers are rarely in that setting. I think it's an understandable decision to force write caching off for the disk holding AD schema. A corrupt domain can be a nightmare.
