WD supply enterprise class SATA drives whose prevailing feature is a low TLER (RE series). This makes the drive report a failed block quickly, rather than trying to recover the blocks for minutes. In a consumer PC, the drive's heroic attempts can save the day. In a raid setup, however, this means that a drive will lock a raided fs until it times out. I would rather have the drive report as failed and let the raid take care of recovering the data. Even if there were no further technical reasons, this feature alone is a great benefit for using these SATA drives in the enterprise justin
