speed, write speed, quite half of vertex 2 public benchmarks.

?
 

did ssd slow down on time, or first time tested it?

of ocz ssds era used sandforce controller, uses compression techniques achieve it's advertised performance.

blackmagic speed test (and many real world applications) use binary/incompressible data results in slower speeds claimed ocz , other vendors using sandforce controller.

have other sort of problem, either ssd or sata cable. if worried numbers not matching claims ocz, might reason.

1 other possibility.... ssd quite full or part used?
searching around finds few issues ocz drives slowing down on time, more full.
