* '''Advantages:'''
** blank tapes are cheap
** the tape drive unit is quiet
** tapes do not require retensioning
** most (if not all) DAT drives feature hardware compression
* '''Disadvantages:'''
** the tape drive units are more expensive than Travan
At our offices, we use a Seagate DDS-3 DAT drive which has served us well.
!!Effectiveness of hardware compression
Our independent tests have shown that on average, you can expect a 1.4:1 or 1.5:1 compression ratio when backing up a file server (including system files).
Thus, you can expect the following tape capacities:
* DDS-2: 4 gig native, approximately 6 gig compressed
* DDS-3: 12 gig native, approximately 18 gig compressed
* DDS-4: 20 gig native, approximately 30 gig compressed
Compression ratios will vary depending on the type of data. Deleted line 27:
