Samsung's 470 Series solid-state drive
 

In the realm of solid-state drives, Samsung's 470 Series is unique. It's the only one we've seen with Toggle DDR NAND, and the first SSD to hit our labs with dual cache chips. Throw in a fresh controller with potential ARM cores under the hood, and we're left with more than a few questions about how the whole thing comes together. Unfortunately, most of them remain unanswered.

We do, however, have a diverse collection of benchmark results that tells us quite a lot about how the 470 Series performs. Generally, it does quite well, offering quick sequential transfer rates and competitive random access times. The drive's strong overall performance isn't fueled by any one test in particular, but by a reasonably strong showing throughout.
