The StorageTek T9940 “capacity-centric” tape drive offers exceptional storage capacity for business applications such as growing archive, backup, record-retention and disaster recovery needs. The ultra-reliable T9940 offers a superior combination of capacity, speed and robustness, in a compact and economical package.

  • A massive 60 gigabyte (native) capacity per cartridge. With compression this typically means 120 to 240 or more gigabytes on a
  • single piece of media. Store a petabyte (1000 terabytes) in a single StorageTek automated tape library.
  • 10 megabytes per second native (up to 37 megabytes compressed)
  • Heterogeneous attachment via ESCON, SCSI and native Fibre Channel connectivity – provides SAN readiness.
  • Advanced engineering componentry and packaging provide the best in data reliability and availability, together with robustness for exceptionally high duty-cycles.

A T9940 capacity-centric tape drive solution works seamlessly with current StorageTek libraries and with Virtual Storage Manager (VSM), so you can enhance the value of your infrastructure investment. The T9940 can help you provide your customers what they need most: fast, economical, robust and accessible storage of ever-increasing amounts of data.


Performance Data
Tape Speed  
   Read/Write 79 IPS (2 m/s)
   Search/Rewind 315 IPS (greater than 8 m/s)
Tape Load and Initialize to Ready 18 s
Search Time 41 s (average 1st search)
Maximum Rewind Time 90 s
Interfaces (per Drive) 1 ESCON, 1 Ultra-SCSI or2 Fibre Channel (SC optical)
Compression Enhanced LZ-1, 4:1 Ratio 
Individual compression achieved is a function of many variables, including the data characteristics. For example, scientific data usually compresses less than general business data. As a practical guide, mainframe (MVS/ESCON) compression rates are typically 4:1, while client server operating systems (UNIX/NT on SCSI or Fibre) usually achieve in the 2:1 to 2.5:1 range. In all instances, slightly lower or significantly higher numbers may be achieved.
