Samsung Electronics has introduced 1.8 and 2.5-inch 64GB solid state drives (SSD) with a serial advanced technology attachment (SATA) II/native SATA interface to form the SATA II SSD. The SATA II SSD is expected to expand the market for solid state drives from notebook PCs to corporate servers and other storage applications.
The SATA II SSD has a sequential write speed of 100MBps and sequential read speed of 120MBps. It combines a 50 nm-class, single-level-cell (SLC) 8Gb flash chip with a high-speed SATA controller and supporting software.
The 64GB SATA II SSD is based on Samsung’s cutting-edge NAND technology with dramatically improved performance specs, said Jim Elliott, director, NAND flash marketing at Samsung Semiconductor.
The SATA II SSD has a 3.0Gbps interface speed, which is twice that of SATA I predecessor and it requires less than half the power compared with the 1.9 watts consumed by hard drives used in notebook PCs. It uses one-tenth of the power consumed by enterprise-class 15,000rpm hard drives in servers.
Samsung has also launched 32GB Parallel ATA (PATA) SSD in March 2006 and a 64GB version using the SATA I interface in March 2007. In October 2007, Samsung introduced a 64GB multi level cell (MLC) NAND flash memory chip, which uses a 30nm class process technology for high density storage.
Another semiconductor manufacturer, SanDisk, also offers SSD SATA 5000 2.5- inch SSD in 4, 8, 16, 32, and 64GB capacities.
