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.

Benchmark Results: Anvil's Storage Utility

We kick off our testing marathon with Anvil's Storage Utility, brand new drives, and a 4 GB test file. 

Plextor's M5S has a great start, yielding the highest overall score. Samsung's 830 performs respectably in the sequential tests, but lags behind in others. And Crucial might have fared better had it not been for a drop in 4 KiB read performance and slower sequential writes speeds.
