Test: OCZ Vertex 3.20

Tags:  HP G6 Battery,  G7 Battery, HP Envy 17T

OCZ now offers shops stamped his latest SSD Vertex 3.20. Beyond simple index change, what are the changes from the model 3.0? Is it as Dell Studio 1558 effective? And at what price?

Since he decided in 2011 to invest the SSD market, OCZ multiplies the good things, like recently with the very grand entrance of his latest disc called NAND Flash Vector (see our test here ). However, on the sidelines of the launch of new products, the American company has not forgotten its ancient references provided, it continues to improve in small steps. This is now the case of Vertex 3, which is adorned with a new 3.20 index winner in passing some interesting Dell Inspiron 1545 fonctionnnalités.

And contrary to what is usually done, this renumbering owes nothing to chance. The number "20" in fact refers to the fineness of engraving that characterizes the new NAND Flash chips (Intel MLC) required for data storage. For the record, these are the same chips found in the Intel 335 Series products, and we had the opportunity to evaluate in a previous test. And as things are done well, the Intel and OCZ SSDs have the same controller, namely a LSI SandForce SF-2281.

However, let's be clear: if the  Dell E4300 Battery internal specifications leave hope for the best performance side, the packaging is meanwhile more minimalist, comprising only the disk without cables or hardware.

A renewal is good?

The side of the storage size, there is no particular distinguish change from version 3.0 of the range. OCZ still has two disks, one 120GB and the other 240GB, with, as you can see in the table below, the  XPS M1330 performance in sequential mode are identical. However, in random disk access is a bit different, for writing 4K block. Of course, these results provided by OCZ are shown on compressible data, on which the SF-2281 controller excels.

Not surprisingly, these are the numbers we decided to check first. Crystal Disk Mark with software that generates incompressible data, obtained some much the same IOPS performance. On the one hand, the

 Dell E4310 Battery test back 35,087 IOPS random 4K block read and 64,575 IOPS for writing the same data type.

On the ATTO test, which in turn generates highly compressible data, the speed is a little slower than expected, but it still remains on good performance with 539 MB / s sequential read and 514 MB / s sequential write. With the  HP G42 Battery test suite from Futuremark PCMark 7, the Vertex 3.20 offers the luxury of dropping directly in 6th place in the standings with 5278 points. Stronger yet, it moves just one point and even Samsung 830 passes over the last Sandisk SSD, the Ultra Plus 256 GB

As for pricing chosen, the gain is significant compared to the previous generation. Compare our price, OCZ Vertex 3.20 shows a price of € 0.69 per GB. A comparison with the same SSD in the Intel HP G4 Battery  brand that appears to € 0.76 GB, OCZ drive is cheaper. In so doing, our performance index / price, it takes the fifth place on the all SSD passed through our hands. Undeniably, the consumer has won everything in this update, even if the software side still deserves some optimizations, Intel seems to have been carried out on its own SSD.
