The folks at OCZ have today revealed their latest bit of hardware in the Z-Drive R4, running at 2,800MB/sec, over 500,000 input output operations per second with one SuperScale controller. One as in single. Then there's a dual version at 5,600MB/sec and 1.2 MILLION IOPS. These monsters are not aimed at private users, instead going for enterprise users, thusly the prices are not yet listed. You'll find that these units are available with SLC / MLC NAND flash memory, customer-chosen configurations, and functionality based on the requests of those laying down the bucks.
