So the weird thing with SATA2 was that we've been shouting for years that the SATA2 controller was a massive bottleneck, interestingly enough we are facing the same challenges already for SATA3 as we've reached that threshold in performance. The 20nm NAND flash uses comes from IMFT. IM Flash Technologies (IMFT) by the way is a joint venture of Micron Technology and Intel.

The SSD is available in three volume sizes: 128GB, 256GB and 512GB are available. Prices are (MSRP in USD) $129.99, $234.99 and $499.99 resepectively.
Passing 500 MB/sec performance really is something you won't hear us complaining about. The OCZ Vertex 450 is an SSD based on Synchronous MLC NAND flash memory made on a 20nm fabrication process. The end result here is that you'll get a storage unit with a sweet IO performance, peaking up-to 540 MB/sec in read performance and a scorching 530 MB/sec write performance. This number varies a bit depending on the NAND volume size though.
The Indilinx Barefoot 3 M10 controller
New in the Vertex series is the Barefoot 3 controller, similar to the one used in the Vector series. The 20nm IMFT ONFi NAND flash memory is tied towards Barefoot 3 controller located. This is an 8-channel NAND flash controller and the third revision from Indilinx, it comes with an all to familiar dual-core ARM architecture.The Barefoot 3 controller makes used of pretty big memory partitions for caching, that means that internal DDR3 memory is used and physically placed onto the PCB being used as file and data caches. The Vertex 450 has 512MB of cache divided over two 256MB ICs from Micron.
Over the SATA3 / SATA 6 Gb/s interface you may expect read speeds up to 550 MB/s and writes up to 530 MB/s based on volume size of the SSD. Both the 256GMB and 512GB model will have these performance numbers. The 128GB model will however have less write performance at 300 MB/sec. All these models have an advertised 4K random IOPS rating in-between 80,000 random read and 90,000 random write (4K aligned).
OCZ Vertex 460 SSD review We review and test the OCZ Vertex 460 SSD series released in 120 - 240 and 480 GB versions. Based on the Indilinx Barefoot 3 controller we test the 120GB NAND flash memory based model. The end result is an ...
OCZ Vertex 450 SSD review 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.
