I can't keep up to you two....

WARNING: RAID 0 means you are using striping without any redundancy, so if you lose one of your 2 disks you are fucked.

FYI, RAID levels are:
RAID0 - striping: data is spread over 2 disks, written at the same time, so faster, but no redundancy
RAID1 - mirroring: two disks are written with the same data at the same time, so safer
RAID5 - 3 or more disks are written to at the same time, data is written to 2 disks and a checksum is written to the 3rd disk. The checksum is rotated over 3 disks. Technically you can pull out any of the disks in a RAID5 array and still run the computer without any loss of data, but replacing this (failed) disk with a new one causes a lot of overhead as data has to be recalcuated. Advantage is safety and speed, where speed increases if you have more disks in an array. Disadvantage is more overhead contsantly calculating the checksums.
RAID10 = RAID 1 + 0, two RAID 0 arrays that are mirrored with each other. Very fast, very safe, most expensive.
