"Western Digital Corp. today announced it is now shipping in volume hard drives offering Serial ATA (SATA) interface with 300 MB/s burst data transfer rate. The new WD CaviarŪ SE16 hard drives feature 16 MB cache - 2 to 8 times the cache size of standard desktop-class hard drives - which, combined with its 300 MB/s transfer rate, deliver a one-two performance punch for customers. The new desktop-class hard drives are available now from WD-authorized distributors and in OEM PCs. State-of-the-art SATA with 300 MB/s performance that is up to 3 times faster than EIDE make WD Caviar SE16 drives one of the fastest desktop-class hard drives on the market, perfectly suited for use in high-performance computers, multimedia and gaming systems." Wow! 16 MB cache! My first computer hard drive was smaller than that. These should be smoking fast and are supposed to be quite also. They should be available now at about $199 for a 250 GB.
