The sequential write results tell a very different story. Although the new Vertex 2 is still slower than the original Vertex drive, the Intel X25-M is seen crashing and burning, as it is slower than the Samsung hard drive. The Intel X25-M again does well when measuring 4K threaded performance, delivering by far our best result. However the Vertex 2 is the best performing SandForce SSD in this test delivering 89% more performance than the original Vertex. The 4K-64 Thread performance of the SandForce SSDs is simply amazing, with the Vertex 2 delivering over 8x more performance than the original Vertex. The Vertex 2 was slightly slower than the Vertex LE and Vertex Pro drives here, though only by a small margin. The read access time of the Vertex 2 is the slowest of the SSDs we tested, while the Vertex 2 Pro and Intel X25-M are by far the best. Interestingly, the Vertex 2 is 51% slower than the original Vertex SSD in this test. Although the Vertex 2 did poorly in the read access times, it does much better when measuring the write access time.
