I have the opportunity to possibly make some changes to my computer configuration. Originally, I set up two (2) 74GB 10,000 RPM Raptor Drives in a Raid 0 Stripe configuration. The idea was to have those two drives working together as one 148 GB drive. This configuration was also designed to increase overall speed. I do understand the risks. If one drive fails, so does the other. In fact, that has already happened within the first year of use Fortunately, the computer is under warranty. the drive was replaced, and everything was backed up to an external drive so no data ever got lost. But now I am looking to possibly consider a change..... I don't know what it is called, but some have suggested it may be better taking the two (2) separate raptor drives and setting them up as mirrored drives where all the information on ONE drive is automatically mirrored on the other. The downside, I suppose, is that I'll lose 74GB. of available storage on the second drive. No big deal as I have another drive with 200GB of storage. So, what would be the overall advantage of changing from a Raid 0 setup to a mirrored setup? Would you recommend this over my current Raid 0 setup? Finally, in order to make this change is it just an issue of making a simple change in the BIOS? Thanks in advance!
