OCZ to come out with new VERTEX SSD,S equiped with 64MB OF CACHE starting at $129

[Peakr]

The higher density NAND on the Apex, is actually faster, thus, the 120 and 250 achieve better speed

So basically it comes down to apex being more suited to hardware controllers while vertex, with its onboard cache, does better with software ones like ICH9 or 10 for instance?
