IBM Half-high LTO Generation 4 SAS Tape Drive
Supported on Ultrium 4 media in increments of 30 MBps to 120 MBps
Along with a larger buffer, helps to maximize drive performance when data
rates are less than optimal
Together with Digital Speed Matching, helps the drive mitigate fluctuations in
data rates
With the 256 MB buffer, helps you achieve optimal performance and storage
capacity
Helps improve data throughput and tape repositions
Helps support data integrity through synchronous, dynamic swapping of data
compression scheme
Helps keep the data on your tape media secure with encryption
Helps meet compliance requirements
Helps improve performance of your backup processes with dedicated
encryption/decryption core
Increases data throughput to support higher drive speeds
Patented technology that provides greater precision when writing data to tape
Enables the drive to support the use of narrower tracks
With the 16 channel head, linear density of the data is increased by 31% when
compared to LTO Generation 3 drives
Improves error recovery and provides greater reliability when loading threading
and unloading tape cartridges
Independent loader and threader motors, coupled with positive pin retention
helps retain the pin during a miss-pick and helps improve load & thread
reliability
Designed to improve drive and media reliability
Allows the drive to adjust to variations in the media and head while calibrating
the channel.
Helps improve data throughput rates and data integrity
Based on IBM copper chip technology, provides improved performance while
providing lower overall power consumption over previous generations of LTO
drives
Enables the drive to operate in write mode and idle mode for when the drive is
not in use
Improves heat dissipation and provides greater operational efficiency than
previous-generation LTO drives
