OCZ Technology announce SATA 6Gbps SSDs

As I predicted a couple of weeks ago, OCZ Technology would be the first to announce SSDs using the new SandForce 2000 family of SSD controllers, and SATA 6Gbps.

The CES show 2011 is already into full swing, and OCZ have been showing their new range of SSDs for early 2011 release.

First up we have the SLC NAND based Vertex 3 EX.

Vertex 3 EX

The Vertex 3 EX will be available in capacities from 64GB right up to 512GB, using a SandForce SF-2582 SSD controller and a SATA 6Gbps interface.

Read speeds are up to a whopping 550MB/s, and write speeds are equally impressive at up to 525MB/s. 4K random write is a staggering 80,000 IOPS. The Vertex 3 EX also employs “Power loss data protection” most likely by fitting a super capacitor.

The Vertex 3 EX is aimed at the enterprise market, where speed and durability is a must.

Vertex 3 Pro

Next up we have the MLC based Vertex 3 Pro.

Again the Vertex 3 Pro uses the new SandForce SF-2582 SSD controller and SATA 6Gbps, but this time married to MLC or eMLC (enterprise grade MLC) NAND.

Once again the specifications are mouth watering, with read speeds of up to 550MB/s and write speeds of up to 525MB/s. 4K random write is not quite as high as the SLC based EX, but none the less 75,000 IOPS is staggering. Power loss data protection is also used in the Vertex 3 Pro, so again I would expect to see a super cap, which is able to power the drive long enough during a power outage to make sure that any data not yet committed to NAND is written.

The Vertex 3 Pro will be aimed at the enterprise and home PC enthusiast, and capacities range from 64GB to 512GB.

Z-Drive R3

OCZ were also showing a new updated Z-Drive, the R3.


The original Z-Drive used multiple Indilinx Barefoot SSD controllers, but this time OCZ have switched controllers to the SandForce SF-1565.

The drive is housed on a PCIe2 x8 card, along with 4x SandForce SF-1565 SSD controllers and 4 banks of either MLC, eMLC, or SLC NAND.

The specifications are certainly extreme, with read speeds of up to 1GB/s, and write speeds of up to 950MB/s. 4K random writes are also extreme, with up to 135,000 IOPS.

Once again we see the super cap, so this would suggest the drive is aimed at the enterprise market. Capacities range from 150GB right up to 1.2TB.


OCZ launched a range of SSDs last year using a new high speed interface, HSDL (high speed data link), and this year at CES, OCZ were showing off what this high speed interface can do, with a new technology sample. I will leave the outrageous specifications to speak for themselves.

Now you have something to fill those optical drive spaces in your PC.


No prices were available at this time for any of these drives, but they should start to appear in just a few weeks time. Going by the type of NAND used, and the use of a super cap, it seems like these drives are aimed mostly at the enterprise market, and we may have to wait a little while for the mainstream models to become available.

We will keep you posted.
