OCZ Vertex 3 240GB reviewed

OCZ Vertex 3 BoxToday I’m going to show you how the OCZ Vertex 3 performed in our tests. This drive doesn’t need to be presented, it was the company’s flagship solution previous the release of the Vertex 4. Under the hood, there is a SandForce SF-2281 controller that can pump up to 60,000 IOPS for random 4KB write operation.

The SandForce controller isn’t only fast, it performs data deduplication and data compression reducing write amplification under the 1x value. So a Vertex drive will last much longer compared to its competitors.

At the first release this drive was affected by some bugs causing random BSODs and headaches. Latest firmware releases addressed the problem: if you have a SandForce-based drive and haven’t updated it yet, it’s time to do so.

The drive is protected by a standard 2.5″ metal enclousure.

I tested the performance on my bench-rig. It’s a Sandy Bridge based platform, not expensive and so very common.

Here is the list of hardware components:

Intel Core i3 2120 skt 1155
ASRock H67M motherboard
4GB of Corsair value ram 1333MHz C9
Seagate Barracuda 7200.12 500GB as main drive
Intel SSD 320

I used the following benchmarks:

Intel NASPT – I know it was developed to benchmark network attached storages, but it does a nice job even with HDs and SSDs
ATTO
AS-SSD – both transfer rate and copy tests

Here are the results plots:

NASPT - Vertex 3
ATTO Write - Vertex 3
ATTO Read - Vertex 3
AS-SSD Write - Vertex 3
AS-SSD Read - Vertex 3
AS-SSD Write IOPS
AS-SSD Read IOPS
AS-SSD Copy Benchmark

As you can see, the Vertex 3 is able to deliver better performance than the Crucial M4. For most of benchmarks the gap is quite limited but when you need to push with 4KB random writes the SandForce controller shows its potential. The claimed 60K IOPS are confirmed by my tests. This drive is awesome.

You know, Vertex 3 isn’t a new product, today the price is about 300 bucks and that’s a sweet spot considering the performance it’s able to deliver and the capacity. About the same price as the Crucial M4 that has bigger capacity but it’s slightly slower. I can’t say which one is better but I can assure you that whatever you buy you are going to be a really good purchase. Even today, the Vertex 3 is a great solution, well done OCZ!
