DLT-7000 has superior performance only if your system can stream data to the drive at the speed the drive writes to tape. As soon as the drive has to stop, rewind and resynchronize, the performance drops back to DLT-4000 levels, and the longevity of the drive falls remarkably. In the systems I work with, DLT-7000 is only an option for backing up local drives. As soon as I start backing up over the network, the DLT-4000 has better performance and better reliability. > I think DDS-3 drives are at >or below $1k. The DLT-4000 is cheaper, but DDS-3 gets really close >to the performance, and at a better price. But DLT is head and shoulders about DAT for reliability. And with a backup medium, reliability is the paramount concern, IMHO. I wouldn't swap my DLT-4000s for any number of DDS drives. ...Richard.
