Unylogix AMA-400000 Drive Specifications

(Based on the Sony AIT-4 drive)
ATI-3 Drive
Model Overview

AIT-4 Internal SCSI Drive OEM Model

Model Highlights

  • High capacity storage for data security and archiving °V up to 200 GB native storage capacity, or 520 GB compressed (2.6:1) in a compact, 3.5" half-height form-factor.
  • Sophisticated data transfer rate of 24 MB/s native and 62.4 MB/s compressed (assuming 2.6:1) provides high performance for today°¶s most demanding environments °V backup up to 86.4 GB/hour native or 224 GB/hour compressed (assuming 2.6:1).
  • Extremely durable Advanced Metal Evaporated (AME) media °V provides a virtually contamination-free environment reducing the need for periodic cleaning, and extraordinary reliability.
  • Sophisticated data access capability with Remote Memory-In-Cassette (R-MIC), a 64-kbit memory chip embedded into the data cartridge °V provides high speed file location and file access.
  • Super Head CleanerĄ°P mechanism °V provides an automated cleaning solution increasing head life and reducing the need for periodic cleaning.
  • Adaptive Lossless Data Compression (ALDC) provides greater data compression efficiency °V offers average compression of 2.6:1.
  • Helical scan recording writes the tape in one pass with a slow tape speed °V reduces wear-and-tear on the tape media and drive, increasing reliability and head life.
  • Backward read-and-write compatible with AIT-3 media and backward read compatible with AIT-2 and AIT-1 media °V offers flexibility and convenience, and provides investment protection.


Features:

High capacity, high performance
ny AIT-4 tape drives deliver up to 520 GB capacity (with 2.6:1 compression) in a compact, 8mm data cartridge. Helical scan technology increases data recording density, while offering fast data transfer rates of up to 62.4 MB/s (2.6:1 compression).

Fast access to data with MIC
The unique Memory-In-Cassette feature of Sony AIT drives, with 64 kbits of built-in memory, speeds access to data, providing fast loading (14 seconds) and quick file access (52 seconds).

High reliability
Sony AIT tape drives incorporate a redesigned head geometry, reducing head/tape pressure and delivering up to 50,000 hours of head life. The built-in Super Head CleanerĄ∑ mechanism results in an industry leading MTBF rating of 400,000 POH (100% duty cycle).

Backward Compatibility
Sony AIT-4 tape drives are fully read and write compatible with AIT-3 media, and are read compatible with AIT-2 and AIT-1 media. Backward compatibility helps protect your investment in the valuable data you already have stored on previous generation AIT data cartridges, while delivering the increased capacity and performance of AIT-4 technology.

Reduced periodic maintenance
Sony AIT drives use Advanced Metal Evaporated (AME) media, which contains pure evaporated cobalt and is sealed with a super-durable Diamond-Like Carbon (DLC) coating. In addition, AIT drives incorporate a Super Head CleanerĄ∑ mechanism that is activated automatically when tape errors approach a certain threshold. Together, the AME media and Super Head CleanerĄ∑ mechanism result in extraordinary reliability and virtually eliminate the need for periodic cleaning.
