The HP StorageWorks DAT 40 tape drive is a fast, dependable backup solution for smaller servers. This DDS-4 tape drive stores 40 GB of compressed data on a single cartridge at a rate of 21.6 GB/hr (assuming 2:1 data compression), providing an ideal balance between capacity and performance.
- Native Capacity: 20GB
- Compressed Capacity: 40GB
- Buffer Size: 8MB
- Sustained Transfer Rate (Native): 3MB/s
- Sustained Transfer Rate (With 2:1 Data Compression): 6MB/s
- MTBF: 400,000 Hours at 12% duty cycle
- SCSI Interface: Wide SCSI-2, LVD/SE
Automated Head Cleaning: HP DDS drives benefit from an automatic head cleaning "sweeper" that can be used during the write or read recovery procedure to dislodge debris from the tape path and recording heads and drive. This feature reduces the need to use a DDS cleaning cartridge for manual cleaning.
Compression: DDS uses built-in hardware compression using the 'DCLZ' data compression algorithm. Data compression is host-selectable with the default that compression is turned on. Typical data compression is 2:1, but actual compression depends on the type of data being compressed and can be more or less than 2:1.
Compatibility: HP's extensive compatibility testing program assures that HP StorageWorks DAT drives work with leading servers, operating systems, and backup applications -- and not just those sold by HP. HP DAT drives work seamlessly in many environments, making them especially suitable if you have a mixed system environment.
