''SATA defines a roadmap starting at 1.5Gbit/s and migrating to 3Gbit/s, evolving to today's 6Gbit/s transfer rate, and then to even higher data rates,'' according to the Serial ATA International Organisation.

Greenliant, SanDisk and others provide embedded SSD solutions based on the technology. Unlike some competitors, Greenliant has developed its own NAND controller, giving it an advantage in the market, Kroyan said.

Greenliant's new SATA NANDrive is suited for data storage applications in portable computing, STBs, industrial, automotive and networking systems. The products are SATA II compliant (Gen1: 1.5Gbit/s, Gen2: 3Gbit/s). The products have a sustained read performance of up to 1.2GBit/s and a sustained write performance up to up 0.6GBit/s.

The 3.3V and 1.2V devices are said to have active-mode power consumption as low as 500mW. It also features a deep power-down mode to further reduce power consumption to 10mW.

The advanced security features of SATA NANDrive include a device ID, password protection and four independent zones that the user can set to different protection levels. Greenliant's NAND management technology is based on advanced static and dynamic wear-levelling algorithms that maximise the NANDrive lifespan.

Greenliant is now sampling the GLS85LS NANDrive line with customers on select product engagements. The devices come in a tiny form factor, measuring 14mm x 24mm x 1.85mm. The NANDrive is offered in a 145 BGA, 1mm ball pitch package.
