Hello,

  Ahhh that is not true. RAID 5 is much, much faster than a mirror (RAID 1). I believe you are thinking about mirrored + striped which is RAID10 (also know as 1+0). That is faster than RAID 5 but requires 4 disks where RAID 5 requires 3.

Since you said you've got a fairly small amount of data (5GB), definitely
go with mirroring rather than RAID. It's much faster.
