(Typically, users will be able to compress data at a 2 to 1 ratio; however, this depends on the data itself.)
6 MB/s maximum asynchronous, 40 MB/s maximum synchronous
50 seconds average file access time using a DDS-4 data cartridge
Max 15 drives per Ultra3 SCSI controller however performance will be impaired. In order to achieve performance
expectations it is strongly recommended that no more than one drive is connected to the SCSI bus.
