i searched these forums and most info about RAID is over 1 year old and i know RAID has come up in the world since then. i also googled for info on RAID and that info is over 2 years old. can someone explain the different types of RAID (1-5 or whatever) and then explain the purposes behind them? i have never did RAID be4 and am considering doing so in my next build. granted that i find it necessary. do you still need a floppy drive for the installation of RAID? i will be using a MB with RAID onboard with SATA. pretty much all i know about RAID at this time is that it's enabled from within the BIOS and one of the RAID's config is 2 drives seen as 1 for performance or something and then 3 drives mirroring or what not. lol. that's about it. thorough explaination is GREATLY appreciated. thx!
