OCZ Vertex 3 240GB SATA 3 SSD Review – Crystal DiskMark, AS SSD, HDTach and Win7 WEI

CRYSTAL DISKMARK VER. 3.0.1 X64 (Random Data)

This is the basic Crystal test where many go wrong in testing SandForce controlled SSDs.  For the Vertex 3, OCZ lists the maximum write speed to be 525MB/s whereas it is shown here as 292MB/s.  The reader should understand that this result has absolutely no bearing on end performance and is just an anamoly we see when testing SandForce SSDs with random data.

We can still see, however, that the all important 4kb random score has pushed even higher at 102MB/s.

AS SSD BENCHMARK VER. 1.5

AS SSD is the other software benchmark that typically uses random data in testing.  These tests are key in showing the absolutely amazing access time of an SSD (.1-.2ms) compared to that of a hard drive (9-10ms) and its also good to see an example of where the claim of 60, 000 IOPS at 4kb is valid as can be seen with the 55722 iops here.

HD TACH VER 3.0.4.0

The average speed shown in HDTach is just under 400MB/s which is why we like to show the same performance measurement through a number of benchmarks.  This one is low compared to all others, however, something has to be said of the 494MB/s burst speed which, once again, is the highest we have seen from a SSD.

WIN7 EXPERIENCE INDEX

The Win7 Experience Index represents Microsofts method of rating computer systems and, more specific to our usage provides a storage evaluation which provides a rating up to 8 on the PC components and system as a whole.  Our system produce a HDD score of 7.9 out of 8 and, for the first time, we are going to pass on a bit of a Win7 secret that all can try.  It will give you detailed information about this score.

  • Go to Win Orb/All programs/Accessories and right click on the Command prompt;
  • Click ‘Run as Administrator’
  • In DOS, type ‘winsat disk’ and hit enter.

Neat little trick eh?  Our results are as shown:

    These look very good!
    Now I do have a question: what would be faster 2x 120GB vertex 3 or 1x 240GB vertex 3?

    Please let me know!
    Thanks 🙂

    • Of course the 2x would be logically faster but, for the typical user, they would notice no difference. In fact, one might even challenge an enthusiast to tell the difference through visual observation.
