Hard Drives Go Flash: Samsung Flash SSD
Tom's Hardware has a nice piece this morning presenting Samsung's new 32 GB Flash Solid State Hard Disk. How does these new drives measure up against traditional IDE hard disks and what are the implications for desktop and mobility users? A very interesting read.
Most attempts to speed up storage performance either use caches to store data that is used frequently, or they deploy faster memory solutions such as SDRAM or DDR-SDRAM. However, all of these require the steady supply of energy by means of buffer batteries or by sucking power out of the grid. Solid state hard drives based on Flash memory are similar to SDRAM-based solutions, but they are unaffected by power-related volatility issues, which plague SDRAM units. Data that is written to Flash stays - even throughout power interruptions.
