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, 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, but still today, there are issues to contend with.
In the remaining PCMark Vantage hard drive tests, the updated Gen 2 Intel X25-M SSD once again pulls ahead of its predecessor. The 'Adding Music To Windows Media Player' test was a dead heat, but in the other three tests the newer drive pulled ahead by margins ranging from 2.16MB/s to 11.49MB/s. With the exception of the Application Loading test, the OCZ and Corsair drives appear to have an advantage here.
