Chapter 13 Using the Tape Drive

Optimizing Tape Drive Performance

DLT-S4 Product Manual 122

• Check the host block size.

The DLT-S4 tape drive supports block sizes up to 16 MB. In general,

the larger the block size, the better the throughput. Many older

software applications default to a 512-byte block size, which results

in poor performance.

• Ensure that you are using a cartridge that is compatible with the tape

drive.
