Moving NAND-based storage architecture forward, Toshiba’s first solid state drives offer three densities: 32 gigabytes (GB), 64GB and 128GB. SSD enable low power consumption, a fast boot time, and light weight, but market penetration has been held back by low densities and high prices. Toshiba’s new SSD integrate an original MLC controller supporting fast read-write speeds, parallel data transfers and wear leveling, and achieve performance levels comparable to those of single-level NAND flash SSD. By applying MLC technology, Toshiba has realized a 128GB density in a 1.8 inch form factor. Toshiba expects the launch of its SSD line-up to speed up acceptance of solid state memory in laptops and digital consumer products, and to widen the horizons of the NAND flash market.
The new products utilize NAND flash memory fabricated with 56nm process technology, along with controller chips and DRAM, on a 70.6mm (L) x 53.6mm (W) x 3.0mm (H) platform. The maximum read speed is 100MB a second, and the maximum write speed of 40MB a second with the SATA2 interface (transfer rate of 3Gbps), which is compliant with high speed serial interface. The operating life is 1,000,000 hours*1.
