Correct me if I'm wrong, but if I have three 250Gb SATA drives in Raid

If my understanding is correct, I should just be seeing one ~250Gb
partition?

Well you shouldn't be seeing one ~250GB drive if you have 3 250GB drives
in a RAID 5 configuration. You _should_ see on drive with about ~500GB
on it as 1/3 of the total drive space is used for parity across all 3
drives.
So what I'm saying is, I don't have a clue why you're showing ~900GB
when even with those 3 drives striped you should only see ~750GB.
You might want to check your drive sizes... The numbers you're showing
there indicate you've got 3x 500GB drives in the system setup in a raid 5
configuration.
