Sandisk has updated its line of solid-state drives (SSDs) for tablet and portable computers with models that have a SATA III interface and can transfer data at  double the speed. The drives have been shown off at the Computex trade fair in Taipei.

The new SanDisk drives are in two product families the U100 SSDs and the iSSD drives. The U100 SSDs are designed for ultra-thin laptops and are available in 8GB to 256GB capacities. Data can be read from the U100 at up to 450MB per second and written to the drive at up to 340MB per second.

The iSSD drives are targeted at tablet PCs and store between 8GB and 128GB. They come in a BGA-type package, which features solder dimples on the underside for direct attachment to the tablet PC's circuit board. Maximum speeds are up to 450MB per second for reading and up to 160MB per second for writing.
