OCZ announced their new Vertex 3.20 SSD as a refresh Vertex 3 back in February. In case you did not know, the actual Vertex 3 has reached EOL status and OCZ will not be manufacturing any more Vertex 3 for the market. Instead, Vertex 3.20 will replace all current Vertex 3 shipments.
These new SSD will be manufactured with 20nm MLC NAND flash as compared to previous 25nm. As the drive has just reached our shores, we put it to the test to let you have a comparison between the two drives, allowing you to make a more informed choice when buying a new SSD in 2013.
The set coming into Singapore will be packaged as above. That also means that it will not come with 2.5″ to 3.5″ brackets for those who want to put it in a standard 3.5″ hard drive slot. Packaging is rather simple, and hopefully will reduce actual prices when it reaches stores.
|SATA 3.0 Interface|
Both Vertex 3 and Vertex 3.20 uses the same SandForce SF-2281 controller. The difference between the two SSD is the changed in NAND chip component. Vertex 3.20 now uses a new Intel 20nm flash chip.
|ATTO Disk Benchmark|
ATTO Disk Benchmark does indeed show that the SSD plateaus at the rated speeds based on its specifications, i.e. 550MB/s Read and 520MB/s Write.
|Read Tests on HD Tune Pro|
|Write Tests on HD Tune Pro|
As for HD Tune Pro which in fact is a utility used mainly for hard drives, we are still able to see sustained speeds on the SSD for random access reads and writes, which shows that speeds for both 1MB and random sizes to be above 400MB/s. However, when dealing with smaller transfer size, the drive is seen to suffer when compared to higher end models like OCZ Vector and Samsung 840 Pro with Vertex 3.20 at only half the speed.
