Solid State Storage - Where we are heading
Solid State Disk (SSD) has actually been around for many years. Some of the first 20MB (yes MB) drives started showing up as early as the mid-late 80's. In those days the application is many cases was focused towards early supercomputer applications from Cray, Amdahl, etc. The challenge back then was both price and longevity. Based on RAM technologies these drives had to maintain powered states and really couldn't support one of the key tenants of disk storage which was data integrity over an extended period like you could with magnetic disk - "the hard drive". In the 90's, Negative-And or NAND Flash memory technology was had been developed by Toshiba in the mid-80's started to see their first applications is what we commonly call today "thumb" drives and SD cards. Designed for camera and PDA applications - NAND showed real promise as a storage media that was inexpensive and could support long term storage. With early NAND Flash the challeng...
