CCE Reviews posted a review on the OCZ 30GB Vertex (OCZSSD2-1VTX30G) SSD

The OCZ Vertex is leaps and bounds better than the original JMicron Solid State Drive. If you're an owner of the first generation drives and noticing your performance and system is starting to fall behind, it is time for an upgrade. I was originally pleased with the JMicron MLC SSD but after a few short weeks of use my notebook started to hang for a few seconds at a time. As OCZ clearly indicated on their packaging, my OCZ Vertex gives me faster access times resulting in a far more stable machine. The 64MB cache has made a world of difference and OCZ didn't sacrifice too much bandwidth for the improved access time. We're still well into the 140MB/s Write and 200MB/s Read. With Win7 just around the corner and the OCZ Vertex already claiming to support the TRIM command, OCZ's Vertex has a very bright future ahead of itself.
