I know these drives are drives are not on the HCL but does anyone have experience running them successfully in a Pro 6 unit? Or any ReadyNAS unit for that matter? The prices have dropped pretty significantly and are almost on par with the 3TB version. I'm looking at the Deskstar 7200RPM version, which is the 3 year warranty consumer grade drive, with RVS but lacking the "enhanced" RVS of the enterprise class Ultrastar drives. Any thoughts on this?
While not officially supported users have found 4TB drives to work find for them. YMMV. If you do choose to use unsupported disks it is especially important that you make sure that your backup of important data primarily stored on the NAS is up to date.
Also note a few expansion limitations.
1. Online expansion is limited to 8TB over the life of the volume. If your volume was 5.4TB in capacity when you last did a factory default you cannot expand past 13.4TB. 2. Expansion past 16TB is not possible. You would need to factory default with the drives in place. This limitation shouldn't be an issue unless you intend to use X-RAID2 single-redundancy (definitely not recommended if using 6x 4TB disks).
they run about 10c higher than the samsungs that they replaced
