That's saved me at least once! Huh? There are different RAID types. There's some to increase redundancy and some to increase performance. Let's take a look a 2 disks not used for redundancy but for performance. Since the pci bus is not the bottleneck with a single drive, but the drive itself, it does make sense to write/read to more than one drive in parallel until the pci bus becomes the bottleneck. And of course the speed increase holds for both write and read operations. 2 Disks. need to write 10meg of data each disk has a throughput oof let's say 5meg/s writing the 10 megs to a single of the two disks takes 2s. writing 5megs to the one disk and 5meg to the other will complete the operation in 1s. Performance increase. For this performance increase one pays the price of less redundancy though (instead of the chance of one disk failing you got the chance of each one of both disks failing combined).
