Hot on the heels of its M5S, Plextor sent us the M5 Pro. Loaded with hot new technologies like 19 nm NAND and the latest Marvell controller, the company's flagship was certainly worth waiting for. How does it do against the established incumbents, though?
Plextor's optical drives were always known for their quality. Now, the company is trying to carry that reputation over to SSDs. Its M5S is actually a fourth-generation offering based on Marvell's controller technology. But Plextor adds its own spin, too.
In our recent look at the Vertex 4 SSD equipped with firmware 1.4, we found that the 128 GB drive's write performance depended heavily on available capacity. OCZ disagreed, but then quickly rolled out firmware 1.5. So, we're back to test the new build.
Back in April, we published one of the first reviews of OCZ's Vertex 4. In those three months, the company has issued three firmware updates, with a fourth reportedly in the pipeline. We take another look at the drive using its latest software.
