SONY





























 SDX-300C AIT Drive   With optimized information access features, the AIT Drive is designed to handle the upcoming explosion of data storage management.

In businesses around the globe, there is an immediate need for cost-effective, high-speed, large-capacity tape storage that can reliably back up large-scale network servers handling huge volumes of images and other storage-intensive data. To meet this growing business demand, Sony has unveiled new standards in tape storage technology. The AIT (Advanced Intelligent Tape) format is Sony's latest innovation in fast access high density tape recording technology.

AIT forms the basis of Sony's new SDX series of tape drives and media. The ability to store large amounts of data and retrieve information quickly is critical in today's applications. Tape storage and retrieval has been revolutionized by Sony's award-winning Memory in Cassette (MIC) architecture. The MIC consists of a memory chip built into the data cartridge which holds the system's log and other user-definable information. Applications that benefit from MIC's capabilities include hierarchical storage management, video server, film editing, and real-time data acquisition.

High Speed Data Transfer
With a recording density of 116 KBPI, the SDX-300C offers a sustained data transfer rate of 3.0 MB/s (native) to over 6 MB/s (compressed)*. The drive uses a fast/wide SCSI with a burst transfer rate of 20 MB/s.

Large Cartridge Capacity
The SDX-300C family can store 25 GB (native) or 50 GB (compressed)* on a single 8 mm size data cartridge.

System Design Convenience
The SDX-300C family includes a fast/wide SCSI interface with a 68-pin single-ended or differential interface or an 80-pin SCA connector and a self cooling design.

Exceptional Reliability
Utilizing SonyÕs extensive technology expertise in 8 mm tape recording, the SDX-300C products are designed to provide 200,000 hour MTBF, an average head life of 50,000 hours and an average of 30,000 media uses.*

Memory-in-Cassette
Incorporating a flash memory chip within the data cartridge, the SDX-300C provides ultra fast media load and fast file search as well as the ability for applications to read and write to the memory chip.

Media Compatibility
The SDX-300C family is designed exclusively for use with SonyÕs Advanced Metal Evaporated (AME) media technology incorporating pure cobalt metallization with a super-durable Òdiamond-like carbon coating" (DLC). AME tape is available with or without Memory-In-Cassette (MIC).
