  1. Affordable 10TB drives availability?

    Considering 10TB is the top of the heap (or damned close), I'd say not for a while. When 12TB and 14TB drives become more common, maybe. 8TB externals are as cheap as $170 pretty often, I'd consider that to be about as big as gets affordable if you don't mind shucking drives.
  2. Intel Optane 900P vs Samsung 950 PRO

    IIRC early reviews for gaming (are there any?) would probably show no difference. I highly doubt Star Citizen would at this stage in its development, it smells like pure, 100% marketing. That may change-- a big issue now is that lots of software is coded expecting to have to deal with a harddisk for storage, so they design for high latency. In a future world where developers can assume everyone has a SSD, they can presumably expect less latency and hence design as such.
  3. If it's the exact same price, maybe. But I wouldn't pay significantly more for one. TLER, for example, is necessary for multi-drive arrays but actually a potential drawback in desktop use.
  4. New Samsung 850 and new Samsung 860

    You can read the Tom's Hardware article as well as the rest of us. It has some educated guesses in there.
  5. Intel Optane 900P vs Samsung 950 PRO

    That's impossible to say without knowing if your current tasks are disk I/O bound or not. If they are, then you might. If they're not, then you won't. Keep in mind that Optane appears to have its main benefits at very low I/O loads over conventional SSDs. If you want a more facetious answer: if you have to ask, the answer is no.
  6. Hmm, might want to check reviews then-- it's not necessarily the rated sound output, but the character of the sound that you'd be concerned about-- any irritating recalibration noises or whatnot? As far as reliability, I'd say in a single drive fleet (or even a half dozen) it's all going to be similar enough that you wouldn't be able to tell. Again the chances of a drive being mishandled somewhere along the way is probably going to do far greater damage to a drive's reliability than any differences between models. I don't think going for a nearline drive is going to actually buy you anything over a consumer drive given your requirements. For drives with a track record in the 2TB range, honestly, everything currently on the market is pretty is pretty established at this point.
  7. Also, for reliability, note that how a drive is handing during the picking/packing/shipping process probably matters more to its reliability than any make/model variation from the manufacturer. IIRC helium-filled drives might have slightly better acoustics than an equivalent platter count conventional drive, but you're probably barking up the wrong tree at that point, you should pay more attention to what's quiet regardless of technology.
  8. What exactly are you trying to do? How many Exchange databases do you have? This sounds very much like something you'd need to ask in an Exchange forum, not a storage forum, as it's fundamentally an Exchange implementation question.
  9. SATA or SAS - will it matter?

    You won't see a performance difference in actual use. Pick a type and standardize on it for ease of maintenance later.
  10. I think that's the same line we've been hearing from Seagate every year, only they keep adding a year to it every year...
  11. Is it a engineering thing to make it reliable, or is it a cost thing to make it cheap enough to mass produce? From what little I've read it seems like the former, given the strain on the substrate of 400C+ temps. (I realize it's a somewhat related set of questions!)
  12. MAMR and SMR can be used at the same time, it doesn't eliminate manufacturers from using SMR. It's about $/GB, so this sounds pretty good if it can maintain the current cost per gigabyte advantage of harddisks... I'm curious if this will actually hit, reading the details on some other sites makes this look much more promising for near-term implementation than HAMR, and it may actually kill HAMR entirely, at least in near-term?
  13. From your "UEFI and Legacy" are you trying to boot off of the same partition? Or just access data?
  14. WD My Book Duo 20GB Review Discussion

    The harddisks inside can't saturate USB 3.1 Gen 1 at 5Gbps, so there would be only limited benefit at best to USB 3.1 Gen 2 at 10Gbps. SR's (limited) benchmarks show only ~364MB/sec in RAID0, which is within USB 3.1 Gen 1's transfer speeds-- or are you seeing more limitations than that in your own use? (if so, sources? I'd be curious, since I honestly haven't kept a very close eye on dual-drive external enclosures lately!) I agree, you might see a limitation at peak speeds, but I wonder how much of that matters in typical customer use for these drives, given that sustained performance seems a more likely use case for a majority of the data transferred.
  15. Storage Spaces vs unRAID

    I assume you're using 3.5" to 5.25" bay adapters? IIRC that case, formidable as it is, is only up to 10 (or was it 13?) 3.5" drives from the factory.
  16. Storage Spaces vs unRAID

    What kind of enclosure are you considering? 21 drives is a pretty decent amount, larger than what just about any desktop case will take along with standard (not-storage-oriented) rackmounts, but still a lot smaller than one of Blackblaze's (and similar) storage pods...
  17. Good catch. Didn't notice, although I was wondering when other makers were going to sell us SMR disks...
  18. Drool. Price on 12TB units isn't that bad right now, I imagine that's because 14TB ones were about to drop...
  19. 200TB SAN/NAS for feature film

    I'm not particularly familiar with Storage Spaces, sorry. Maybe someone else can answer? As far as budget RAID/ZFS solutions, well, ZFS and Storage Spaces are all software/OS based so there's zero point to a hardware RAID card in those scenarios.
  20. 200TB SAN/NAS for feature film

    10 cores each is plenty, you can go waaay lower end than that., down to a single Xeon 3104 would be more than overkill. Our NAS builds are all single quad-core setups, I think the oldest is a single Core 2 Quad-era rig if you need perspective. Your workload for the NAS is going to be so low that you're never going to push the CPUs anywhere near rated TDP except maybe when rebuilding the RAID/ZFS pool, and even then I doubt that's going to remotely stress it.
  21. 200TB SAN/NAS for feature film

    Mmm, that's more of a software question than I am familiar with. Most OS'es can support both SMB/CIFS (Windows) as well as NFS (Linux) as well as several other protocols with the right drivers/plugins, so generally it's not a problem with anything reasonably well developed. NAS4free, FreeNAS, Windows Server, whatever... Again nearly entry level CPUs should be just fine, unfortunately I don't have/can't supply benchmark numbers like Kevin does for the hardware I have on hand.
  22. 200TB SAN/NAS for feature film

    20x 12TB nearline disks are what, $700 each so $8400 right there, put them in two 10-drive RAID6's (or RAIDZ2) and you end up with 180TB usable, which might be cutting it pretty close since with disks that full you'd have no space to defragment effectively. (1TB in works out to 931.5GiB typically if memory serves--I could be off...) In theory you can do this but you'd probably have to DIY it to make it cost-effective, I'm not sure any vendor would do it-- although I can imagine some smaller 3rd-tier players being able to build it for you for $25k.
  23. Off roader anyone?

    Nope, sorry. I do have more friends than I expected into offroading, mostly Land Cruisers and whatnot...
  24. Crucial M500 alternative

    If your actual disk I/O requires are low then pretty much anything should work, including the MX300. 850 EVO actually has near best in class performance as Samsung has a significant headstart on both 3D NAND as well as TLC vs. their competitors, the 850 Pro is ahead of it (perhaps near the very top of SATA SSDs for consumer use), but it smells like either of those might be a waste of money for your use.
