OCZ Vertex 3.20 SSD review -
Specifications and Features
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
- Up to 550MB/s Sequential Read
- Up to 520MB/s Sequential Write
- Up to 35,000 IOPS 4k Random Read
- Up to 65,000 IOPS 4k Random Write
- Available in 120GB, 240GB

The Vertex 3.20 SSD
In this article we test, benchmark and review the all new OCZ Vertex 450 SSD. Armed with the new Indilinx Barefoot 3 controller this is the fifth incarnation of the popular OCZ Vertex series. Will it be as fast and competitive as it's predecessors ? Well let's see and find out shall we ?
OCZ Vertex 3.20 SSD review
In this article we test, benchmark and review the OCZ Vertex 3.20 SSD. What a great and fast piece of technology this is. An 20nm NAND flash SSD that is speedy and actually amongst the the rest of the devices tested, but also mroe affordable. Head on over into the review.
OCZ Vertex 4 SSD review with 1.5 firmware
We retest the OCZ Vertex 4 SSD yet now with 1.5 firmware update. , again bringing more performance towards the Vertex 4 series of SSDs. And albeit the difference is not as big as the 1.4 release was, it certainly makes a difference as this article will show you.
OCZ Vertex 4 SSD revisited with FW 1.4RC review
We revisit the OCZ Vertex 4 256 and 512GB SSD review, this time with Firmware 1.4 which makes the drives much faster. Armed with a new Indilinx Everest 2 controller this SSD is advertised as one of the fastest on the block with screaming IOPs performance. Lets have a look shall we ?
