The Vertex 3’s maximum write rate is given as 525 MB/s, a very high level. The previous Vertex model, the OCZ Vertex 2, reaches its maximum at around 285 MB/s (difference of 48.18%), and the difference quickly becomes clear. The Intel SSD 510 series (Elmcrest) is around 40 MB behind (difference: 7.28%) at its peak. The drives with SATA 2 hit a plateau from this packet size onwards, but the OCZ Vertex 3 still has plenty to give, settling at a constant high level of around 550 MB/s for packet sizes beyond 1 GB. Only after this point does the true reading performance of the SATA 3 port reveal itself. The read rates up until 16 MB are average, and comparable with other slower solid state drives. This is the tool of choice for most manufacturers, as it gives the highest transfer rates, and so generally meets the published marketing figures. The first of our tests is the ATTO Disk benchmark, which looks at read and write transfers of packet sizes between 512 KB and 8 GB. ![]() The retail version of the Vertex 3 will probably come packaged with some screws for mounting, a 3.5-inch mounting frame, a small OCZ sticker and a handbook. TRIM can now also be activated under Mac OS X 10.6.7 ( as we have reported). The TRIM command and Garbage Collection (GC) are supported. OCZ has been working closely with the firm, and the firmware is also being specially adapted for the Vertex 3. To match the new SATA 3 port, the drive also features the new SandForce SF-2281 controller. In the case of the Vertex 2, however, this is not an improvement - on the contrary, in fact, it slightly worsens its speed and theoretically its life span too. In addition, OCZ also introduced its predecessor, the Vertex 2, with 25 nm memory chips (SATA 2). ![]() Inside it is MLC flash memory made with the modern 25 nm process. In its final state the drive is supposed to weigh 77 g but our sample model is considerably heavier at 91 g. The firmware and choice of materials for the casing will be modified before it is launched. ![]() What we are looking at is still a sample model for marketing purposes. In our review, however, we take a detailed look at the OCZ Vertex 3 with 240 GB. There are currently no firm recommended retail prices for the SSDs, but the 120 GB model should be sold for around €249. Delivery problems are being experienced because of the earthquake in Japan, because Toshiba manufactures its flash memory there. Most retailers list the Vertex 3 SSD in its 120, 240 and 480 GB models. According to its marketing information, it should be possible to achieve 550 MB/s reading and 525 MB/s writing. ![]() OCZ Technology unveiled the first models of the Vertex 3 Pro and EX Generation at the Consumer Electronics Show (CES) 2011, and also introduced the new high-end consumer SSD Vertex 3 at CeBIT 2011. With this in mind we also try using the new SSD in a netbook with a SATA 2 Connector (3 GBit/s). Despite the maximum transfer rate of 6 GBit/s, we are still dealing with a standardized port, which is therefore backwards compatible. There is currently no mobile platform from AMD that supports SATA 3 and with it 6 GBit/s the forthcoming Llano APUs are the first that will be ready for it. With Intel’s Huron River platform and the new Sandy Bridge CPUs, SATA 3 has also gained entry to mobile devices.
