Ignoring price/capacity, 2 X25-E 64GB's or OCZ Colossus for i7 iMac.

Consider price is relatively no object. Would you rather install an OCZ Colossus or 2 X25-E 64GB in a RAID using an Adata XPG EX92 SSD Hard Drive Enclosure? Keep in mind I'm more concerned with performance/speed than with drive capacity.

I'm planning on making my 27" i7 iMac the best it can be. Once I chose a SSD option, I'll be purchasing a Panasonic UJ-235-A Slim Slot-Loading Blu-ray Combo Disc Drive. Also some 1333Mhz RAM to replace the stock 1066Mhz.

2 x X25-E would be faster but because iMac has only SATA 3Gb/s, it'll be a bottleneck. 2 x X25-E have maximum read speed of ~540MB/s but SATA 3Gb/s have real world performance of ~300MB/s so you would be losing a LOT.
