Great drives - no benefit to a DVR though... DVR's simply don't have the throughput to be hindered by even some of the slowest magnetic drives on the market today. Plus, with the high volume writes and rewrites a DVR creates, you'd be killing sectors fast, and running on a lifetime shorter than most magnetic drives. Now, for a general use system drive, those new SSD's are awesome...

Personally, I think the best option for DVR's are the more ruggedized high capacity drives - not necessarily fast, but designed for a LOT of reads and writes - like the WD Purple line.

Yeah, instead of 20 years they might only last 10

Even the 840 which died "early" had over 800TB or writes, which is 819,200GB, at 2GB/hr, that's 409,600 hours of recording, or 17,066 days, 46 years.

My point was the cost being incredibly high for no practical benefit.

[stanger89]

Well yeah, we'll see what they cost I guess.

Recommended use
WD Purple storage is tested and recommended for use in surveillance and security systems up to 8 bays and optimized for 32 HD cameras. For additional surveillance capacity, look at WD datacenter hard drives. WD Purple is not recommended for use in NAS environments, please consider using WD Red hard drives for desktop RAID and NAS environments or WD datacenter hard drives for rackmount or large RAID configurations.

Any idea why these wouldn't be recommended for a NAS? (and I guess what I'm really wondering is how they are different than Red.)

sorry for the slight threadjack

[stanger89]

Could be a firmware thing, the Reds have TLER, maybe the Purple's don't?

Data integrity if you can suffer lost bits and bytes the purple drives might be okay.

Something to do with how they handle errors in a RAID setup. I lost data when using WD green drives. I switched to red drives and haven't had a problem in the first 2-3 years.

If nothing else, if the price was right they could be great for a movie repository (mostly reading, little writing), vs. conventional HD's which draw a lot of power and generate a lot of heat even when idle.

Would be nice to have 30-50TB of archival DV storage that only burned a couple watts total when idle and 5 or 10 watts reading or writing.

well, if you are only using a drive for reading when watching a movie, the drive should be spun down the rest of the time, so power draw should not be a concern.

Just seems like trying to find a use for one of these in sage is a solution looking for a problem.

I have a pair of 4-drive boxes that plex into a pair of eSATA connections. Inside those boxes I keep various large/slow HDDs with archives of all my stuff. They only get powered on to be used, and about once a year I'll activate them and do a full disk scan/check (HDDREGEN is my tool of choice) just to make sure there's no signs of degredation. So far *knocks on wood furniture so hard I bloodied a knuckle* I've had no data loss issues. I do worry with the fact I have 3TB and 4TB drives now that recovery could be painful.

I've considered SSDs in the past for primary storage, namely because of the power saving. I haven't had time to run the math though to see what that works out to though.

What I would LOVE to see if someone come out with an SSD that has chips that are speed optimized to be just fast enough to saturate SATA2 or SATA3 links, use the absolute least power necessary, and cost significantly less than the "fast" cousins. That to me would be a killer drive for HTPC usage, as well as other applications.

I'm thinking about gettng some of these newer high-capacity drives. My server is running 32 bit Windows7. How can I tell if my hardware and software will support these 5 and 6 TB drives?

You should check the number of available SATA headers on your motherboard, for these drives it won't matter if your SATA2 or SATA3. I believe most motherboards will support it, but I suppose it would be worth making sure your motherboard supports GPT partitions - if you're doing one partition it will need to be GPT. I don't know your plans, but I would not put the boot operation system on a large GPT drive.

I would use them for video storage only. My boot drive is solid state.

I "THINK" there is a patch needed for Windows 7 to handle 2TB+ drives, but I run 64 bit on everything, so I'm not 100% sure it's for both 32 and 64 bit machines. (Just did a google, and as long as you don't boot from it, Windows 7+ supports 2.2TB+ drives on everything, or so says the web. Oops, only if EFI/UEFI BIOS)

Tom, I think you're good to go with the GPT partition.

Ah, thanks.
