PCWorld heeft een review van de Promise FastTrack, een UDMA controller waarmee je met doodnormale IDE schijven een EIDE RAID kunt bouwen die de performance theoretisch zou kunnen verdubbelen:
Promise markets the FastTrak as an EIDE performance booster rather promoting it with its technical description, which is a smart move considering that most consumers have no idea what an EIDE RAID controller is. RAID may sound like something you'd use to keep ants out of your kitchen, but it really stands for redundant array of independent disks. RAID is a standard for using multiple smaller-capacity drives in place of one premium-priced larger drive to boost performance and improve data reliability. It's been used for years in SCSI-based network servers, but the higher cost of SCSI has kept it out of the EIDE-dominated desktop market. By striping (or splitting) files into pieces laid across multiple drives, the FastTrak adds to total data bandwidth. As an analogy, think of running water into a pool using multiple hoses: You'll fill the pool a lot faster than you would using only one hose. Promise doesn't advertise it, but the FastTrak also supports drive mirroring, or using a second drive to maintain a continual, exact copy of the first. If you mirror the drive, you don't get a speedup, but you do get the insurance of a copy in case one drive fails.
Dat ding lijkt me erg vet!
