Hard drives go solid state


Sandisk has begun production of a 1.8", 32GB flash-based hard drive.

Intended for high-end PDAs and ultra-light laptops, the disk is:

- more robust than a conventional hard drive (mean time between failures of 2 million hours, or 229 years!)

- more energy efficent (0.4 watt during active operation versus 1.0 watt for a conventional 1.8" hard drive)

- faster (sustained rate of 62MBps) more than 100 times faster than HDDs for random 512B reads

(all figures supplied by Sandisk)

Excellent. Now all we need is our 1TB solid-state 3.5" drives and we're set.

Wonder how much cheaper solid-state is in comparison to current tech at today's capacities?

Hi Skep

Flash memory currently costs about £12 per GB.

You can pick up a 500gb 'moving parts' hard drive for £100.

And with Seagate recently predicting that their new technologies will allow them to squeeze 300 TERABYTES of information on a standard 3.5-inch drive by 2010, I don't think we'll be seeing the death of the 'old-school' drives any time soon!
