Western Digital Announces New Solid State Drives

Western Digital on Wednesday announced a new line of 2.5-inch solid state drives (SSDs) that use a SATA 3GBps interface. The SiliconEdge Blue SSD is a consumer focused drive meant for use in both portable and desktop computers.

The SiliconEdge Blue SSD come in 64GB, 128GB and 256GB capacities, with list prices of $279, $529 and $999, respectively. The company claims 250MBps read speeds and 170MBps write speeds.

Unlike typical hard drives, SSDs have no moving parts. They don't have to spin up, so start up times and application launch times can be faster. SSDs are also more resistant to shock and vibration than spinning hard drives. On the other hand, SSDs are more expensive and have less capacity than standard hard drives.

The SiliconEdge Blue SSD uses multi-level cell, or MLC technology which is typical for consumer SSDs as it offers higher capacity and a lower price than single level cell, or SLC, memory popular in enterprise-class applications for its higher reliability.

Speaking of SLC, WD also announced a higher-end SSD product line today that uses that technology. The SiliconDrive N1x isn't being marketed to end users, rather it is designed for "embedded system OEM applications."
