LaCie 2big Quadra - Drive Swapping
 

I've got a 2TB LaCie 2big Quadra that I use as my work drive for edits for (set to RAID 0). If I want to purchase new drives, do I have to go with LaCie's 2big spare drives...

(LaCie - LaCie 2big Spare Drive)

or can I buy something like this...

(1TB Samsung Spinpoint F3R HE103SJ 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive)

and swap the drive out of the casing with the key lock?
