7-Way SSD Round-Up: Sandforce vs. JMicron
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...
We saw more of the same in the remainder of the PCMark Vantage tests. The SandForce based drives continue their strong performance here, with little to separate the OCZ, Corsair, and OWC drives. And the 120GB offerings continued to perform just like the 100GB drives.
