Will Flash Solid State Replace Hard Drives?


Will your next laptop lack a hard drive?

Yes, if Samsung has anything to say about it. The electronics maker is looking to kick off an era of flash-based solid state drives (SDD) that approach usable capacities. That is, they can store enough for an OS and a healthy batch of applications, with some room left over for assorted files.

The company today announced a 1.8-inch, 64 gigabyte (GB) flash hard drive replacement that offers twice the capacity of the SSD Samsung debuted last year.

Samsung's drive is built using 8 Gb single-level-cell (SLC) NAND technology, which the company credits for the drive's improved performance, not only over traditional disk-based storage, but over its predecessor as well. Samsung's 64 GB SSD can achieve read speeds of 64 MB per second and write speeds of 45 MB per second while drawing half a watt of power during drive activity. The unit draws just 0.1 watts at idle, or 1/15th the power required for a conventional 80 GB hard drive.

Mass production of the Samsung 64 GB SSD is scheduled for 2Q 2007.
