In 2008, disk seeks are still on the same order of magnitude as they were 10 years ago (nearly 10ms), but applications have become a lot more demanding than they used to be. Solid state memory is not (yet?) cheap enough to fully replace disks for most people. However, fast flash memory devices are becoming very affordable (around $50 for a 4GB size, 30MB/second throughput flash memory device). It
