Flash memory is the holy grail of data storage. Fast, resilient, and desirable. Unfortunately it’s also expensive and unable to support as much capacity as its moving part cousins. The price issue is not likely to go away for quite some time, with solid state drives expected to command a premium for the next little while. The capacity, however, is looking more and more promising. SanDisk has announced that they will have 64 GB SS drives by the end of this year, doubling their current 32 GB offerings. These are likely to cost an arm and a leg, but the prospect of being able to realistically replace your laptop’s perpendicular recording drive for a flash based system might be too appealing to pass up. The drives will come in 1.8″ and 2.5″ flavors, and should be out by Q3 of this year.
