OCZ Vertex 450 256 GB SSD Review: Can We Call It Vector Jr.?

Results: 128 KB Sequential Performance

Once again, we turn to Iometer to measure the most basic performance parameters.

Fantastic sequential read and write performance is a trademark of modern SSDs. To measure it, we use incompressible data over a 16 GB LBA space and then test at queue depths from one to 16. We're reporting these numbers in binary (where 1 KB equals 1024) instead of decimal (where 1 KB is 1000 bytes). When necessary, we're also limiting the scale of the chart to help readability.

128 KB Sequential Read

Just about every newer SSD ends up past the 500 MB/s mark with 8 or 16 outstanding commands. The most notable differences come into play at lower queue depths, particularly when the queue depth is one or two. Only Corsair's Neutron GTX is outside the 400 MB/s+ norm, starting at just over half of that.

OCZ's Vertex 450 doesn't crush the competition, but it does pick up another 100 MB/s from a queue depth of one to four. The company's Vector maintains a 20 MB/s lead over its Vertex 450 until the results become indistinguishable, once commands are stacked high.

128 KB Sequential Write

The Vector and Vertex both handle 128 KB writes with aplomb. They exceed 500 MB/s beyond a queue depth of two. Of the drives we're including, only the SK Hynix Memory Solutions (LAMD)- based Seagate and Corsair SSDs are much of a threat to OCZ's offerings.

It's true that the Vertex 450 isn't quite as fast. Through a queue depth of 16, though, the Vertex only trails by single digits. In other words, the two drives go neck and neck.

    Kinda wanted to see 840 pro match up with it too. Guess it doesn't really matter since we could just go find your other benchies on it and compare it ourselves but i thought it would just be nice to have it up there.

    Speed and performance are fine but what really counts is reliability which OCZ does not have. I had to RMA Vertex 2 twice and both times it lasted 8 months. Before that I invested in an Intel x25-m and it is still going strong.

    Just bought another 840 Pro. Really can't trust OCZ anymore after so many failed Vertex 3s.

    It is pretty common to find quality SSDs in the $0.55-0.65/GB range these days. Game coupon aside, the price of this SSD isn't all that competitive.

    I love OCZ The Vertex4 series SSDs have been nothing but rock solid reliable, much better then their earlier offerings and the problems with the Vertex2/3 series drives

    The Vector gets the Far Cry 3 coupon until July 14th while the Vertex 450 doesn't get it at all. If you're having to choose between the two, the Vector is probably the better bet unless the V450 is significantly cheaper. It's hard to say what the Vertex 450 will cost once generally available, but it'd be prudent to expect prices to be higher for the first few weeks. Initially, the Vertex 450 will probably be near the $235 mark, only a few bucks less than the Vector (about $15). Is it worth giving up two years of warranty and a FC3 coupon to save $15? You be the judge.

    Stay tuned, because we're working on it. I've been rebuilding the entire database of comparative consumer SSD performance data, and some drives haven't been done yet for one reason or another. In some cases, it's due to time constraints. In other cases, acquiring or reacquiring particular SSDs has been problematic.

    I'd like to see it's relative performance compared to a Vertex 4. I have two Vertex 4 drives, a 256 and a 128, and I've been wondering how these new drives would compare, and if they're worth spending the money to swap with my Vertex drives.

    Later in its life, the Vertex 4 shipped with Micron NAND, eschewing Intel's flash for a slight performance drop and better pricing.

    Doesn't Intel and Micron use the same NAND via the IMFT partnership?
