To be honest with you, talking to you guys has opened up my eyes to how little I really know lol. Ok, so I remember a friend told me that to raid a hard drive means to have two hard drives connected to eachother and have data saved to both so that retrieving that data will be a much quicker job. Is that right?
Raid 0 is reading and writing to-two or more hardrives simultaneously. Also called striping, when the data that is written to both hardrives, one file is split apart in to pieces and distributed to the drives in the array, all at the same time (actually, that gets fairly deep in discussion due to clock cycles in CPU, nothing is absolutely simultaneous, I don't even think dual cores are).
Other common options are Raid 1: mirroring-writes complete files to both drives -redundant, safe array for constant data backup, however if corrupted data is written to one it is also written to the other. Raid 0 +1 is a combo of the two. Raid JBOD (just a bunch of discs) to be made to look like one drive - data is written normally. I am fairly familiar with all these Raid arrays in a MS Winbolws environment, but no clue in debian/ linux setups
Raid 5 & Raid 10 ?? Cant remember.
