     Serial ATA hard drives, although still a little hard to find, are finally available! Thanks to Seagate, we can now take advantage of the performance SATA has promised. Seagate has sent over not one, but TWO 120gb Barracuda Serial ATA V hard drives. Sure, I've been wanting to try out a single SATA hard drive for a long time, but I've been looking forward to running SATA RAID even more!

     Over the past couple months, my crew and I have been playing around with SATA adapters and SATA controllers. As much as I've been looking forward to Serial ATA, it really doesn't offer you any data transfer performance increase while using today's standard IDE hard drives with SATA to IDE adapters. Sure, some of these adapters work very well, but do not expect any kind of data transfer performance increase. However, SATA uses far less CPU resources, which does helps overall system performance. Now that we have true SATA hard drives, there should be at least some data transfer performance as well as lower CPU usage. In theory, Serial ATA should give our PCs a considerable performance increase. Let's find out!
