OCZ Vertex 450 256GB review

The latest in OCZ's line up of SSDs is quite the performer

Our Verdict

For

  • Very competitve speeds
  • In-house firmware
  • Nipping at the heels of the Samsung Pro drive

Against

  • Random read speed could be better
  • Pricey

The OCZ Vertex 450 is a beacon of hope and courage in the face of almost totalitarian power. In financial terms, OCZ is but a rounding error on Samsung's balance sheet, so we doff our hats to the firm for bringing this competitive SSD to market.

This is no simple re-badge job. Nor does OCZ simply half-inch components from other companies' shelves. (Well, it does have to take memory chips from the open market. For the record, OCZ uses Micron's 20nm MLC NAND.)

No, the impressive bit is that OCZ makes its own controller chipset. At least, that's the case as far as we can tell. OCZ has previously made claims in this area that didn't quite hold up, but the latest Indilinx Barefoot 3 controller appears to be the real, proprietary deal.

Going by our benchmarks, we'd say that's true, because the 450 carves out something of a unique niche. A lot of our drives are very closely matched, but there are enough differences to make out a pattern.

Verdict

The Vertex 450 is right up there in almost every metric. Sequential reads and writes are close enough to the competition that it hardly matters, and so are our application tests, though you can say that of every drive. Random write performance is as good as it gets, too.

The chink in the armour is random reads. Is 19MB/s versus, say, 26MB/s a disaster? Not really, but since random performance is the metric that most worries us, it's notable.

It's also a shame we couldn't get hold of the 512GB version to see how it fares against Samsung's.
