We've been claiming it for years that the SATA II controller was a bottleneck, interestingly enough we are facing the same challenges already for SATA3 as we've reached that threshold in performance. Still 500 MB/sec performance really is something you won't hear me complaining about! So on this page is where we'll look a little deeper inside the actual product. The OCZ Vertex 3.20 is, as stated, an SSD based on MLC NAND flash memory made on a 20nm fabrication process. The DNA is the very same as the regular Vertex 3 though, aside from a firmware change. The end result here is that you'll get a storage unit with a sweet IO performance, peaking up-to 550 MB/sec in read performance and a scorching 500 MB/sec write performance. All that at a better price level.
Based on the award-winning Vertex 3 Series, built with leading-edge NAND flash to deliver a superior user experience and improved application performance compared to hard drives
Includes SandForce’s robust DuraClass™ features that work in tandem to deliver world-class SSD reliability, performance, and power efficiency
DuraWrite™ architecture optimizes the number of program cycles to the flash, effectively extending flash rated endurance by 20x or more when compared to standard SSDs
Advanced wear leveling and monitoring - optimized algorithms further extend flash endurance
Advanced read/program disturb management - safeguards against errant re-programming of cells during read and program cycles
Recycler - intelligently performs garbage collection with the least impact on flash endurance
