The OCZ Vertex 2 Conspiracy: Lost Space, Lost Speed?
Several readers contacted me in the past two weeks, complaining about OCZ's recent adoption of 25 nm NAND and its effect on the capacity and performance of certain SSDs that they expected to be both larger and faster. I bought my own drives to compare.
Benchmark Results: Iometer Streaming
If the previous page got you worked up, then this page of results should help confirm that we’re onto something here. Streaming IOPS and throughput are fundamentally unchanged in shifting from 34 nm NAND to the new 25 nm devices.
The same goes for writes. There’s basically no change. It’s definitely much more conceivable now that the problem stems from processing overhead associated with smaller randomized files and more aggressive ECC.
