PCMark Vantage (cont.)
Our next series of Vantage tests will stress the write performance. Applications like video editing, streaming 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 MLC NAND flash. SSD manufacturers are getting better at this, as is evidenced by our results below...
The remaining four tests in the PCMark Vantage suite told essentially the same story as those from the previous page. Here, the Western Digital drive manages to outpace the Barracuda XT by a small margin in every test.
