4th Generation LTO Features

The new LTO-4 tape drive provides 100% more capacity and 50% greater transfer speed than the popular LTO-3 drive, bringing native capacity to 800GB (1.6TB compressed) and native transfer speed to 120MB per second (240MB/sec compressed).

The increased capacity and speed shortens the time needed for backup and restore processes – a key benefit for companies with increasing data storage requirements and shrinking backup windows.

The LTO-4 drive outperforms all other tape drives in its class on the market today, allowing users to replace multiple drives with a single LTO-4 autoloader, which reduces points of failure in network architecture and lowers the total cost of ownership for tape drive hardware and media.

The next-generation LTO-4 also offers a myriad of features to improve performance, reliability and manageability. With its new hardware-based encryption, the LTO-4 drive can write encrypted data directly to the LTO Ultrium tape cartridge, adding another level of security to the storage and transport of sensitive information.

Digital Speed Matching, a 256 MB buffer and Dynamic Compression all improve drive performance. Diagnostic routines, such as the Statistical Analysis and Reporting System, assist in isolating failures between media and hardware, and Adaptive Tape Threading protects against failures during cartridge loads by verifying tape speed, the tape spinning wheel, and modulating the tape thread by providing tension control.

Independent tape loader and threader motors and positive pin retention ensure that the pin will be retained during a miss-pick. Graceful Dynamic Braking allows the reel motors to gradually decelerate, instead of stopping abruptly during an unexpected power down.
