Though some may have problems with this drive, I think a recent QNAP firmware update worked around a RAID issue by disabling NCQ for this drive. NCQ isn't as helpful except for larger scale multiuser disk access patterns. I'm using 2 WD green 2 TB WD20EADS drives in a TS-219P without any...
Christian, how did you manage to get the ATTO benchmark to run on a network/NAS drive? If I map a network drive to my TS-219P, ATTO does not show it in the drive dropdown list, but only lists local drives.
