I've longed talked to Western Digital about their thoughts on the SSD market. The story has changed from something like "we are committed to magnetic storage" to "we're timing the market," after the purchase of SiliconSystems. SiliconSystems made SSDs in the form of Compact Flash for the industrial and business market. They didn't make true consumer SSD products, but they weren't traditional CF disks that you would find in a high end DSLR.
Today, Western Digital has announced the SiliconEdge Blue line of SSDs. They range in size from 64GB to 256GB and, based on reports, is using the newer JMicron controller. We like when companies break out of their niche when a newer (and better) technology comes around so we're glad to see WD step up to provide SSDs to the consumer market.
WD set some crazy pricing on these drives. The 128GB is suggested to be $529. We highly doubt that you will purchase this drive for that price. Expect it to be in-line with something like the V Series from Kingston, which uses similar parts.
