Another nice find. :) I'd be curious as to the power on hours, but that price per TB is quite nice.

Any "gotchas" with these? Or will any run of the mill SAS3 work? (and out of curiousity, how are they on SAS2?)

In for 8. Much cheaper for my use than even white label WDs.

Just bulk storage in my case. $10/TB compared to $14-$16. For the cost I can self warranty.
Yep and being sas enterprise drives, they're probably built for a longer life than the white labels--so cheaper and better. :)

Do i need to prepare these drives in any special way if I intend them to be used in a napp it appliance, for use as plex storage?

@Mithril The spec sheet says 205MB/s sustained transfer rate. (here) for HUH728080AL5200 (8TB)

205 MegaBytes/s = 1.64 Gigabits/s

SAS3 = 12 Gigabits/s
SAS2 = 6 Gigabits/s
SAS = 3 Gigabits/s

(Caveat) Cache
The spec sheet says 128MB Cache.
Theoretically, transfer rates of 12Gb/s for the first 128MB. Then it drops to 1.64Gb/s (plus the time it takes to flush the 128MB)

Its just a math equation. Take your HW combination and goals then solve for bottlenecks.

In short: a SAS2 controller should work just fine. YMMV

Definitely weird! But the same seller didn't have many of the 10TB so maybe the inventory number was a mistake?

Yeah. Can happen where they listed a whole bunch, but then got private buyers who took a bunch on the side offsite, and then with sales, before you know it, they realized they didn't have enough :.(

No worries though, will look out for a any upcoming deals on drives. Seems like companies are ready to dump out these 8TB drives in favor of double capacity!

Different ad, different seller, but best price at ebay at the moment. If everyone agrees that $80/drive is a great price then I'd argue that $90/drive is pretty good too ;)
