Re: I was thinking of madder things
I'm not sure how good that would be, cost wise:
10x $249 for 4000 GB raw storage = $2490
+ $~45 for the adapter board, plus shipping = $2535
Or you could buy a pair of 2 TB Crucial MX300 SSDs for half that and raid 0 them either using an appropriate sata controller or software raid0, and still have money left over for a proper data backup device.
Performance wise, you'd probably hit the 3 Gbps ceiling that the sata spec that board uses before you'd run out of bandwidth on the cards for read speed.
