Fujitsu Shows 500GB Laptop Drive

[Jitway]

Laptop computer storage is racing fast towards the 500G-byte level with Fujitsu becoming the third hard-disk drive maker to announce a drive at that capacity.

 

Fujitsu is accomplishing this capacity by combining three disk platters-- the magnetically-coated disks on which data is stored-- each with a 170G-byte capacity inside the drive. Hitachi, the first company to announce a 500G-byte drive, and Samsung Electronics are also using three platter designs.

 

The third platter increases the thickness of the drive to 12.5 millimeters versus most other laptop drives, which have just two platters and are 9.5 millimeters thick.

 

As a result the Fujitsu drive won't fit into the drive bay on many laptop computers, so its availability doesn't mean an instant capacity upgrade will be possible for all laptop users. Hitachi's drive is also 12.5 millimeters thick, but Samsung said it has been able to keep the drive height at 9.5 millimeters on its Spinpoint M6 drive.

 

Fujitsu will begin selling its 2.5-inch drive in May. It will have a Serial ATA (SATA) interface and can transfer data at up to 300M bytes per second. The average seek time for reading data on the 4,200 rpm drive is 12 milliseconds and 14 milliseconds for writing data. Fujitsu didn't announce pricing.

 

 

This is truly good news. The more that do this the better the price and the better the quality. I myself could really use this in a laptop and with my business I am always running out of space on mine.
