Sony’s road map for SAIT calls for extending the storage capacity to 4 terabytes with 240 MBps of native speed.

Techopedia Explains Super Advanced Intelligent Tape

SAIT media incorporates Sony’s Advanced Metal Evaporated (AME) tape technology, which facilitates high-density recording. The data transfer rate starts from 30 MBps for the first generation and increases with each subsequent generation. SAIT provides the high data transfer rate through a set of independent read and write heads, which are combined together with high head-to-tape velocity. SAIT media incorporates a memory-in cassette (MIC) flash memory chip, which allows for the storage of important media information and parameters. The chip also enables quick media loads and fast data search. SAIT drives and media implement “write once, read many” functionality to facilitate both conventional erasable recording as well as archiving.

Sony’s SAIT technology offers significant advantages in terms of capacity, reliability, scalability and performance. It also optimizes application performance through short repositioning times, regardless of host data rates.
