Also Toshiba is entering in the SSD market. In fact, today Toshiba announced its entry into the emerging market for NAND-flash-based solid state drive (SSD) with a series of products featuring multilevel-cell (MLC) NAND flash memories.
Toshiba’s solid state drives are designed primarily for notebook PCs, and initially will be available in three densities: 32GB, 64GB and 128GB. Samples and mass production will follow from the first quarter (January to March) of next year.
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.
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.
- Interface: SATA2 (3Gbps)
- Voltage: 3.3V (Module, 1.8" type)/5V (2.5" type)
- Writing speed: Maximum speed at 40MB a second (sequential mode)
- Reading speed: Maximum speed at 100MB a second (sequential mode)
- Temperature: 0 to 70 degrees Celsius
- MTTF*: 1,000,000 hours
