OCZ Vertex 2 Pro, Sandforce Powered SSD Preview
PCMark Vantage (Continued)
Our next series of Vantage tests will stress the current weakness of most SSDs, that being write performance. Applications like video editing and recording are not what we would call a strong suit for the average SSD, due to their high mix of random write transactions. We should also note that it's not so much a weakness of the memory itself, but rather the interface and control algorithms that deal with inherent erase block latency of NAND flash. SSD manufacturers are getting better at this, but still today, there are issues to contend with.
Here, the OCZ Vertex 2 Pro shows exactly what we expected to see, since it's significantly faster with general write performance. In the Movie Player and Media Center tests, the Vertex 2 Pro surges past the Intel X25-M Gen 2 drive by a significant margin, but also falls behind in read-intensive scenarios like application loading and Media Player.
