Helps reduce the time required for backup
50% transfer rate increase from current Half-high LTO Generation 3 drives
Up to 1.6 TB cartridge
capacity
capacity
Helps store greater amounts of data as your business grows
Digital Speed Matching
(DSM)
(DSM)
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
256 MB buffer
Together with Digital Speed Matching, helps the drive mitigate fluctuations in
data rates
Adaptive Data Compression
With the 256 MB buffer, helps you achieve optimal performance and storage
capacity
Helps improve data throughput and tape repositions
Helps improve data throughput and tape repositions
Helps support data integrity through synchronous, dynamic swapping of data
compression scheme
256 AES encryption
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
16 channel head
Increases data throughput to support higher drive speeds
Timing-based servo
positioning
positioning
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
Advanced tape loader and
threader mechanism
threader mechanism
Improves error recovery and provides greater reliability when loading threading
and unloading tape cartridges
Independent loader and threader motors, coupled with positive pin retention
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
reliability
Designed to improve drive and media reliability
“On-the-fly” adaptive channel
calibration
calibration
Allows the drive to adjust to variations in the media and head while calibrating
the channel.
Helps improve data throughput rates and data integrity
