Traditional mechanical are soon going to be a thing of the past with the debut of Solid State disk drives which we first saw on the Sony UX50 UMPC. Sandisk is bringing to the market a 32 gigabyte (GB), 1.8-inch solid state drive (SSD) aimed at enterprise users for now. Using NAND flash and SanDisk’s TrueFFS flash management technology, the SanDisk SSD delivers two million hours mean time between failures (MTBF). With no moving parts, it does not need to spin into action or seek files in the way that conventional hard disk drives do. It is 100 times faster compared to other drives claims Sandisk as it achieves a sustained read rate of 62 megabytes (MB) per second and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer.

A PC equipped with Sandisk SSD will boot Windows Vista enterprise in 35 seconds with an average file access rate of 0.12 milliseconds, compared with 55 seconds and 19 milliseconds of a PC with a traditional hard drive. It is projected that inclusion of the SanDisk 32GB SSD in a notebook PC could increase the end-user price by around $600 USD in the first half of 2007.
