Half High LTO Gen 4 SAS Tape Drive

Features & benefits

Feature	Benefits
Up to 240 MBps data transfer rate 1	Helps reduce the time required for backup
Up to 1.6 TB cartridge capacity 1	Stores greater amounts of data as your business grows
Digital Speed Matching (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 integrity through synchronous, dynamic swapping of data compression scheme
256-bit AES Encryption	Helps keep the data on your tape media secure via 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	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 percent compared to LTO Generation 3 drives
Advanced tape loader and 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 helps retain the pin during a miss-pick and helps improve load & thread reliability Designed to improve drive and media reliability
"On-the-fly" Adaptive channel 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
Copper-based chips	Based on IBM copper chip technology, provides improved performance while providing lower overall power consumption over previous generations of LTO drives
Superior power management	Enables the drive to operate in two modes: 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
WORM support	WORM-capable cartridges give you the option of storing vital data in a non-erasable, non-rewritable format, to meet strict regulatory requirements for data retention Helps address evolving regulatory initiatives
Flexible mounting alternatives	Half-high external SAS tape drive for a low-cost and space-efficient tabletop or shelf unit alternative to mounting a drive internally in your server. 5.25-inch half-high internal SAS tape drive designed for internal installation in IBM System x tower servers or external IBM 1U rack-mount enclosures
