I agree, @TabloTV you need to add the the FAQ at a minimum the link to the tested hard drives. I did a lot of looking around here before I purchased, but customers should not be subjected to that 
Just my 2 cents
Hey folks - We are hard at work on a firmware fix that will enable us to support a wider array of drives.
Until then, we will be adding a link to the hard drive information in as many places as we can so it’s more visible/accessible, including in the order confirmation email for orders from our site.

I’ve just ordered my Tablo dual-tuner and even though it won’t be here for a few days, I thought it prudent to figure out which USB drive to buy. I could have sworn during my research that I’d read somewhere that the drive has to be self-powered and not USB powered, but it looks as though some of the confirmed working drives are USB powered. Is this true?
@saturnnights Yes, I use one of these http://www.amazon.com/gp/product/B00H4XH586/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1

Thanks Jestep! That’s good news, and roughly doubles the number of drives available for the task!

@saturnnights - It’s actually the opposite. We find the drives that are USB powered are best, vs. the ‘plug into the wall’ kind.

Hey everyone,
Has anyone tried the Seagate Backup Plus 1TB for Mac (SRD0SP0)? I’m just curious before I wipe this one I have and try it out on the Tablo. I don’t know if this acts any different than the regular Seagate Backup Plus STD models.

I originally marked this as bad. But under the latest FW 2.1.14 it appears to be working OK. So what ever changes you guys made for the improvements for the USB drives its working.

Can use any brand 5.25 inch internal hard drive(supports 2.5 inch drives but I have not tested them)

COMMENTS: The only trouble I had was when a bad hard drive was being used. The only issues with this I have seen were successfully diagnosed by attaching the hard drive to a real computer via SATA cable and then testing using Seatools Dos or Windows. (I have tried 4 old drives of which 3 had confirmed issues) I bought a new 4TB Seagate drive and found that Tablo would only show 2.16TB of space.
This is a 100% stable solution, not flaky in any way and is as rock solid as the health of the hard drive. This is powered via AC plugin.

Works perfectly. USB powered. I use this on my Plex server and on my Tablo. They stack, that is, they are flat and can stack on top of each other.

@Jestep - Link corrected, thank you.
question, with tablo is there any additional benefit with a 7200 rpm over a 5400 rpm drive?
@brg88tx Not for the Tablo - the RPM’s won’t affect the way the Tablo interacts with the drive. So no cause for concern here!
