    Samsung 860 EVO SSD VS SAS HDD

    They should work just fine, but like anything with not-specifically-tested-as-compatible gear, if you get any weird behaviour, you may be on your own for solving it...

    Toshiba L200

    Reviews are leaking out, will SR's be up soon? Or better yet, a comparison of all the recently released QLC SSDs?

    PCH vs CPU lanes 2018

    LOL, you're at a site that used to post the data translated to either in average latency (ms), IOPS, and MB/sec... wrong place to complain.

    PCH vs CPU lanes 2018

    I'm looking for benchmarks but not seeing any outside of a bunch that do RAID testing, which isn't terribly relevant to single drive setups, since I would be much less surprised at the DMI 3.0 link used on the mid-range and higher chipsets being saturated with a bunch of NVMe drives. For a single drive unfortunately, not seeing anything, although there could still be an impact. However, given DMI 3.0 is basically a PCI-e 3.0 x4 link, and we know even high-end NVMe SSDs using PCI-e 3.0 x4 don't come anywhere close to saturating the link in 4K I/O's, I don't know how much of a concern it actually is. As the Techspot article says, the older DMI 2.0 link on the budget chipsets is a different story. edit: ah! Maybe this? https://www.pcper.com/reviews/Storage/Quick-Look-AMD-Ryzen-X470-NVMe-Storage-Performance

    Samsung 970 Pro 1TB Review Discussion

    Any chance of consumer benchmarks? Just curious, since reviews on the 970 PRO are not super common yet (at least vs. the 970 EVO!).

    Toshiba L200

    Intel 660p?
  7. 9 platters. Damn.

    Toshiba L200

    We care, mostly for a lot of our customers who want easy-to-use, convenience-first, somewhat-rugged, high-capacity... if we could get bigger than 5TB we'd take a bunch in a heartbeat. SSD is overkill for this application due to cost and low I/O performance requirements. That said, I realize that's definitely an edge case...
  9. 2% GM improvement is pretty significant, especially for a company with a lot of commodity products and consequently thin margins!
  10. Dang, nice. I wonder when LSI Logic is going to do the same on their MegaRAID cards.

    Huge project / How to Store & Workflow

    Those three things said... you'd still need to keep editing local for performance reasons, but I would absolutely go cloud storage. You then not only get protection from individual drive failure, but also from potential theft, environmental disasters (flooding, earthquake, volcano, etc. taking out your editing rig), as well as from less-obvious items such as bit rot.
  12. Does the Windows event viewer show anything in the logs? Are system voltages stable? (log them in HWMonitor or something?) If you run the manufacturer's hard drive fitness test, does that show any issues? Since you've tried two different SATA cables, have you tried a different SATA port on the motherboard? If you have and the issue still persists, I would strongly suspect your harddisk is failing and should be replaced immediately.

    HTPC 4k ultra

    Your propose data rates are likely so low it doesn't matter. I would stick to the Avago 3108 for your RAID, unless you prefer to go all software RAID with ZFS or whatnot instead.
  14. For a single drive sample, they'd be exactly the same, or so close you wouldn't be able to tell.

    Reliability of seagate expansion 2.5" 2 TB

    Question-- what timeframes exactly are you addressing in your "as of late" comments? Seagate Barracuda 3TB (ST3000DM001) failure rates are definitely atrocious, but most of our deployments were circa 2011 or 2012 for those, so the ST3000DM001 is far enough in the past, it's is no longer a relevant model for our production. Just curious what timeframes you're looking at. Major auto makers are doing this the past few years, actually. To replace simple parts often requires you have the factory tool to reset the ECM, PCM, TCM, etc. to accept the new part. It's not quite as atrocious as forcing you to take it back to the dealer, but independent shops have been forced to buy the factory diagnostic tools to do a proper ECM/PCM/TCM/etc. reset. Plus they're now applying for and receiving design patents on a lot of parts, so 3rd party makers can't make alternatives (at least not immediately).
  16. I'll be blunt-- that looks slow as hell if it's aimed at "professional" use, nevermind the ratings. Nowhere near the real-world-close-to-100MB/sec-read and 80MB/sec writes that we're used to seeing from Sandisk, Samsung, and Lexar's high-end stuff. Quite disappointing.
  17. Seagate Desktop 8TB's are just fine, but honestly I would grab whatever's cheapest. You shouldn't see too many SMR drives in 8TB aside from the Seagate Archive units, so I wouldn't worry about it-- but again check the spec sheets if you're concerned. Honestly I don't remember what the MacPro drive sleds use for their mounting screw configuration, but as long as you can get in 4 screws to mount it to the drive tray you should be fine.
  18. Check the screw holes on any 8TB and larger drive you're buying-- the last few years as drive capacities have increased, platter counts inside drives have gone up, and the middle set of screw holes in 3.5" drives has disappeared as a result (there's no longer room for them!). Seagate, Toshiba, HGST, WD... all current 8TB drives seem to be fine, I'm not aware of any serious defects floating around. For a desktop I would probably avoid nearline/enterprise drives such as HGST Ultrastar or Seagate Exos/Enterprise Capacity as those are usually tuned for performance, not for low noise. Looks like that Apricorn card is SATA 6Gbps, so ideally you'd use the SATA ports off it it. Power is just an ordinary SATA power cable, I don't remember what kind of power cables are free inside of your MacPro tho so I don't recall what kind of adapters you may need. Honestly if it's just for bulk storage, the SATA 3Gbps ports built-in to the MacPro should be fine, I might consider just using those and not worrying about it.
  19. Peak power for the WD Black 3D and Sandisk Extreme PRO is listed as 9.24W per the spec sheet.

    NVMe 1.2 and 1.3

    https://www.anandtech.com/show/11436/nvme-13-specification-published-new-features Anandtech's got a pretty good article on the differences.

    Seagate 2.5inch NAS

    They're SMR so rebuild performance is probably horrible, if that's something you're worried about... other than that, I got nothin.'

    LSI Bios missing

    Does the LSI card show up as a bootable device in your Gigabyte's UEFI? Is there a selection in there to enable Option ROM support? (not that I think your motherboard is the problem, since your problems all seem to stem from your changing your LSI firmware from IR to IT mode.... but helps to ask.)
  23. Drive-managed SMR is completely invisible to the host OS, so yes, it would be supported.

    External HDD Became RAW

    Woah, kept the files and folder structures? Very nice.
  25. You'd need a software solution since your system doesn't support a separate drive for caching natively. I'm not aware of any 3rd party caching solutions that are recommended. How much usable storage did you need?
