OCZ Vertex 450 SSD Review (256GB) – Back To The Start With Indilinx Success

CRYSTAL DISK INFO VER 5.5.0

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with AAM and APM.

30GB of host writes were present on the Vertex 450 when received, leading us to believe that burn-in testing was conducted on this SSD.

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Listed specifications are 540MB/s read and 525MB/s write performance where our initial ATTO results have reached 551MB/s read and 530MB/s write.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. In the OCZ Vertex 450 SSD, performance results are very similar whether we test with compressible or incompressible data and, for this reason, results are displayed utilizing incompressible data.

For both Crystal Diskmark and AS SSD, we have tested the Vertex 450 in a standard system mode (left) with results that can be expected from the typical PC system, as well as testing in an optimized mode (right).  To better understand optimized testing and it’s customization, check out ‘The SSD Optimization Guide Win8 (and Win7) Edition‘ and see Point 19.

Any clue as to when will a new LSI Sandforce generation of consumer SSDs will reach the market – they seem long overdue…

The SF-2000 Rev B, which is a low power version of the original, has been announced in the last few days but no news on any new version controller.

Thanks.

Maybe they’ll take some more time, like Indilinx took from Vertex 1 to Vector products… but it is a pity as it would create more competition.
