Kenneth D. Merry ca3b51e9ed Disable tagged queueing for the IBM DCAS drives. These drives have poor ... write performance when tagged queueing is enabled. Although the PR was submitted for the 4 gig version of this drive, the assumption is that the 2 gig version has the same problem. Therefore tagged queueing is disabled for both. Also, update the comment for the Western Digital Enterprise drives to note that the best performance for those drives is achieved when tagged queueing is disabled and write caching is enabled.
