1.3.2 Product Overview for the 5157/5157 ACL Drives

The DLT 5157/5157 ACL tape drives are a high-

performance, high-capacity, streaming cartridge tape

product designed for use on midrange and high-end

computing systems. Using data compression and

compaction, the DLT 5157/5157 ACL tape drive features a

formatted capacity of 70.0 GB and a sustained user data

transfer rate of 10.0 MB/s*.

The DLT 5157/5157 ACL tape drives are a 5-1/4 inch form

factor, half-inch tape drive. The design includes a quad-

channel read/write head, Digital Lempel-Ziv (DLZ) high-

efficiency data compression, and tape mark directory to

maximize data throughput and minimize data access time.

*Assumes 2:1 Compression ratio (Data Dependent)

1.4 Fast Data Transfer Rate

Used for unattended backups or archiving, the DLT

5157/5157 ACL tape drive allows the user to back up a

higher data capacity at a higher speed than earlier

products. The DLT 5157/5157 ACL tape drives, when

operating in a non-compressed mode, have a maximum

transfer rate of 5.0 MB/s. When operating in the

compressed mode, the maximum transfer rate is

10.0 MB/s.

1.5 High-Capacity

The DLT 5157/5157 ACL tape drives accept the

DLTtape IV cartridge. When this cartridge is used, the

amount of data stored on the tape can be up to 35.0 GB

non-compressed or 70.0 GB of data using the compression

mode. The actual amount of this data stored in the

compression mode is dependent on the data type.
