Samsung Electronics has developed the first solid-state disk (SSD) based on Nand Flash memory technology. This technology looks set to replace hard disks in laptops and other portable devices, and will be initially available in two sizes – 2.5” and 1.8”. According to the company, since the SSD features no moving parts, it consumes 5% less power and provides better data security than today’s hard disk drives (HDDs). This power-friendly approach will help portable devices, such as notebooks, MP3 players and digital cameras; squeeze more life from one battery charge. SSDs are less than half the weight of comparably sized HDDs and, since they are free from moving parts, these SSDs will make minimal noise and emit less heat than HDDs. Samsung also claims that the SSD’s performance rate exceeds that of a comparably sized HDD by more than 150%. The storage disk reads data at 57MBps and writes it at 32MBps. To ensure compatibility, Samsung’s SSDs have been designed on the same form factor as 1.8” and 2.5” HDDs. The company’s 2.5” SSDs carry 16 Nand Flash chips, of 4Gbit or 8Gbit density, for 8GB and 16GB of storage respectively. Its 1.8” SSD meanwhile will be available from August, for notebooks and tablet PCs. Samsung expects Nand Flash applications to expand from current applications in digital cameras, MP3 players and 3G mobile handsets, to mobile and digital consumer appliances.
