hi i have to purchase an hard drive to make recordings based on mac book pro for audio recording with at least 24 tracks and video postproduction with final cut studio,

i have been suggested lacie raid hard disk but in the past i used IOmega.

what do you suggest me.

I'm interested in picking up a Glyph GT 062 Hard Drive but I can't figure one thing out. Since it supports RAID 0 and 1 is it actually the size its shown to be or is it half of that? For example if I got a 500gb one, would it actually be 250gb?

If you've used one of these drives and have experience with them let me know.
