OCZ Vertex 2 SSD Review
HD Tach, Sandra and Crystal DiskMark

HD Tach
Our last "graph" before the couple of graphs. On the left we can see that utilising an 8mb block of data the Vertex 2 is very consistent indeed with the main peaks coming at regular intervals.
However once we shift to the 32mb data size we find a very inconsistent graph. There is no reason for the drive to be any faster or slower at the beginning or the end as we aren't reading from a moving platter like we are with a standard drive.
Crystal Disk Mark
Finally we bring our old friend Crystal Disk Mark to the party. We will be using it to compare the SandForce controller on the Vertex 2, to the SandForce controller we recently tested with the Mushkin Callisto. For comparison purposes we are also testing the Corsair Nova which uses an Indilinx Barefoot controller, and the Crucial C300 which uses a Micron controller and is the only drive on test which takes advantage of SATA3.
Read Test
Starting off with our write test naturally the C300 walks it, but it's lower down the graph that the interest lies. The OCZ Vertex 2 and Mushkin Callisto use identical hardware, and yet the OCZ has a healthy lead in all of our read tests. Despite the SandForce controller dispensing with the cache chip to hopefully give improved performance, the Corsair Nova still edges ahead in the 4K and 512K testing, but has a big lead in the sequential read test.
Write Test
The write testing was the area the C300 fell down on, and you can see here that all of the drives on test keep up. In the 4K testing the Mushkin Callisto just nips in front, although as every drive performs poorly with this size data variances in testing are more common. Once we move to a size that is more likely in daily use, the Vertex 2 once again comes out ahead although none of the drives can come close to the write speeds that the Corsair Nova provides.

Nice review as ever though
Gave me something to read when the forum was down.
Crystal hates my X32. Reports it wrong, runs like a dog and gives terrible results. ATTO. That really seperates the men from the boys
Although now I'm thinking maybe I should have got one of OCZ's bootable PCI-E drives instead!
