DLT-VS80 Drive Overview
Your DLT-VS80 is a value-priced, high-performance, high-capacity streaming cartridge tape
drive designed for use on entry to mid-range computing platforms. With a combination of
data compression and compaction, your DLT-VS80 offers a formatted, native cartridge
capacity of 40 GB (80 GB assuming a 2:1 compression ratio) and a sustained user data
transfer rate of 3 MB/s (up to 6 MB/s with 2:1 compression). The capacity you realize in
practice depends on the data set, which affects the actual compression ratio.
Your DLT-VS80 is built on a 5-¼ inch, half-height form-factor, using a ½-inch tape. Its
design includes a dual-channel read/write head, Lempel-Ziv (DLZ) high-efficiency data
compression, and tape-mark directory to achieve the fastest data throughput and data
access times.
1.2.1 Fast Data Transfer
Whether you use your DLT-VS80 for unattended backups or archiving, the data transfer
rate your drive achieves is higher than many competing products. Your DLT-VS80’s native
(uncompressed) data transfer rate is 3.0 MB/s. With 2:1 data compression, the data transfer
rate increases to as much as 6.0 MB/s.
