Today, disk drives offer the best dollar to GB ratio. Flash drives have to offer something different like the all new Intel flash drives.

How small are they?

The size of your fingertip. The Z-P140 measures 12 x 18 x 1.8 mm and weighs 0.6 grams – 400 times smaller and 75 times lighter than a 1.8″ hard disk drive. 12 mm is about half an inch.

The Z-P140’s big brother, the Z-P230 PATA SSD, is only 1/4 the size and weight of a 1.8″ drive. Much of that is due to the size of the PATA connector.

What capacity?

The drives will be available in 2, 4, 8 and 16 GB capacities. These capacities are more tailored for cellphones, media players, Eee-class notebooks and the like.

Part of Intel’s offer is size. The other is cost. They’ve priced the drives below where disk drives can go due to unavoidable hardware costs like heads and motors.

The pricing for 1,000 units available Q3 2008 for the 4GB is $25 and the 8GB part is $45. The 16GB will be available in Q4 2008.
