whats the difference between having a hard disk in raid 0 and raid 1. when i placed my 2nd 500gb in i just kinda threw it into the extra slot and plugged it in. :?

RAID 0 is striping and it means that the same data is split across several disks. In theory, that's double the write/read speed with two disks configured in RAID 0 but you won't get that in practice. You retain the capacity of the individual drives, 2 500GB drives give you 1TB but if one drive in your RAID 0 array fails your whole RAID 0 setup will fail.

RAID 1 is called mirroring and it's a backup system where the second drive is a mirror image of the first drive. 2 500GB drives give you only 500GB of storage.

RAID configurations are often used in tandem but you can't just add a new drive in and expect it to configure itself. :wink:

lol i formated it and what not, but im pretty sure its just working as a "mirroring" drive. at least its the same as my external, just internal.

Well....if it's functioning the same way as an external drive then it's probably not functioning as a RAID array. RAID 1 is a seamless and automatic mirror of the first drive onto the second. I was probably wrong in saying it is a "backup" as the data is written to both simultaneously and there is no drive defined as first or second.
