SSDs are a lot faster than traditional HDDs even when they use the same SATA 3Gb/s interface. With the new SATA 6Gb /s interface on the horizon, SSDS and traditional HDDs will get a lot faster. Micron has announced its new 6Gb/s SSDs called the RealSSD C300.
This new SSD is sampling now in limited quantities and Micron says it will be in full production starting in Q1 2010. I guess we can assume boards needed to take advantage of the SSDs will be on the market then too.
Micron will offer the SSDs in 2.5-inch and 1.8-inch form factors for notebooks and desktop systems. The new SSDs promise a read throughput of up to 355MB/s and a wire throughput of up to 215MB/s. Micron reports that on the PC Mark Vantage benchmark the new SSDs scored 45,000.
