OCZ Vertex MAX IOPS SSD

The specifications on the drive are very beefy. Sporting a 550 MBps max read speed, as do many of the other OCZ SATA 6G models, and a 500 MBps top write speed, which is actually 20 MBps slower than the "vanilla" Vertex 3 240 GB model, why would consumers want to pay more for the MaxIOPS variant? 340 MBps 4K write speed. The MaxIOPS pushes past the competition on an important file size for PC users. For those running Apple's OSX, the HFS+ file system also uses a 4K file cluster so the MaxIOPS edition can really improve performance on their boxes as well.
