Sorry, I was referring to the INTERNATIONAL STANDARD
SATA spec as defined by INCITS ". Perhaps you can provide me a reference to this "RAID certified" you keep talking about. Some drives are tested by NAS manufacturers and put on the approved list; this does not mean that all other drives will not work, just that they have not been tested by a particular manufacturer. Different manufacturers have different, often contradictory, lists.
The ST2000DL003 is not recommended because of a firmware bug, that later revisions fixed. Indeed QNAP do state that the drives "passed QNAP lab's initial verification of compatibility". The same could happen to RAID-certified enterprise level drives; people are fallible and make errors. Similarly, the WD EARS drives are not recommended, but will work fine as long as you turn off the aggressive load cycling.
A 2-4 bay NAS has the same drive mount characteristics as a standard PC chassis, so ANY drive that is certified for a PC will work in a small NAS (there is obviously an issue with TLER if it cannot be enabled causing the drive to drop out of the RAID array). Bigger devices may need better vibration handling, which enterprise level drives include.
The ST2000DL003 is CERTIFIED for use in a NAS - by Seagate.
So please, before you keep spouting the same old "not certified", understand what you mean. The drives you mention on your sig are desktop hard drives and NOT enterprise drives - no better than the drives you are criticising.
And, at the risk of also repeating myself, the ST1500DL003 is on the approved list, yet it is EXACTLY the same drive as the ST2000DL003. So how can it appear on this "holy tablet" of approved disks??
