The IBM 7205 Model 550 160 GB External Digital Linear Tape Drive is a stand-alone, SCSI, streaming tape drive that attaches externally to the IBM eServer pSeries and RS/6000 families of servers. The Model 550 160GB External Digital Linear Tape Drive writes data to tape using an advanced laser-guided recording technology. The tape drive provides a media capacity of up to 160 GB (320 GB with 2:1 compression) data storage per cartridge. The 7205 Model 550 tape drive has a sustained data transfer rate of up to 32.0 MB per second with compression, which provides for tape storage backup at the rate of 115 GB per hour.

Model Highlights 7205-550

The Model 550 offers:

• Increased tape capacity of four times that of the 7205 Model 440 -- up to 160 GB native per cartridge (320 GB with 2:1 compression)
• A data transfer rate more than twice that of the Model 440 -- up to 32.0 MB per second

The IBM 7205 Model 550 160 GB External Digital Linear Tape Drive is a large-capacity tape drive that writes data to tape using Super DLT's laser-guided optical servo with an advanced Partial Response Maximum Likelihood (PRML) read channel to sustain performance and data integrity of the S-DLT320 tape drive.

Benefits

Providing an excellent migration path from the 7205 Model 440 DLT8000 tape drives, the Model 550 is a high-capacity, cost-effective solution for your save, restore, and archiving functions.

• The increased storage capacity, up to 160 GB (320 GB with compression), four times the capacity of the IBM 7205 Model 440, reduces the number of tape cartridges needed.
• The 7205 Model 550 has more than twice the data rate of the 7205 Model 440.
• The 7205 Model 550 has full backward read compatibility with the IBM 7205 Model 311 (DLT7000) and 7205 Model 440 (DLT8000) tape drives.

Note: Although the 7205 Model 550 tape drive can give you high tape performance, other components of the system may limit the actual performance achieved. In addition, the compression technology used in the tape drive can double the amount of data that can be stored on the media; however, the actual degree of compression achieved is highly sensitive to the characteristics of the data that is being compressed.
