SATA 2 Performance

SATA 2 Performance



In a perfect world everyone investing in a new solid state drive would have access to a SATA 6GB/s controller which could pass on the TRIM command. In reality not everyone has this and for many the decision comes down either giving up TRIM – never a good idea with most controllers – and running it off a secondary controller; or taking a performance hit and running in SATA 2.0 mode.

These tests will consist of some of our real world and synthetic benchmarks run on our standard 1155 test-bed; but the drive will be attached to an SATA 2 port.

For synthetic we have opted for the newcomer to our charts: Anvil Storage Utilities Pro. For real world we have opted for our Adobe test. These two tests should give you a very good idea of the level of performance impact you can expect from running a modern SATA 6 drive in compatibility mode.






With the wide-ranging adoption of SATA 6Gpbs, this test is becoming slightly less relevant but for a quick upgrade of an older system, the Veterx 450 would be an excellent choice.

Conclusion


OCZ’s Vertex 450 represents a seamless blend of technologies in order to create a drive that caters to budget-conscious buyers but doesn’t sacrifice much in the way of performance. This perfectly follows today’s realities: most end users love reading about ultra high performance drives but they’ll actually go out and buy more affordable alternatives that still offer great real world benchmark numbers. And that’s exactly what OCZ is offering here.

By combining 20nm NAND with the Barefoot 3 controller, OCZ has created an SSD with the chops to compete against some of the competition’s best solutions and only it trails the flagship Vector by a few percentage points. The Vertex 450 also offers a significant performance increase over its predecessor, the well-regarded Vertex 4, as well. Unlike the relatively minor differences between the Vertex 3.20 and the Vertex 3 it replaced, the Vertex 450 256GB is head and shoulders better than its predecessor.

This blurring of mainstream and enthusiast markets mostly comes about by the Vertex 450’s use of Indilinx’s new Barefoot controller rather than the Everest 2 found in some of OCZ’s other drives. The Barefoot M10 may be a down clocked version of this iconic controller, but it has the muscle to effectively support the 20nm NAND and offer great performance to boot. More importantly, as its immature firmware evolves, we’ll likely see even higher performance out of the Vertex 450.

The Vertex 450’s true strength lies in its performance and capacity ratios per dollar against those offered by the likes of Corsair, SanDisk and Crucial. Most other companies have populated the $200 to $275 market with 240GB drives, whereas OCZ has utilized their onboard cache to create a “true” 256GB drive without the need for over-provisioning. While 16GB of additional storage capacity may not seem like much on paper, it will make a world of difference when you’re trying to cram that last Steam game or two onto your drive. In addition to the higher capacity allotment, OCZ's on-the-fly ITGC routines allow the Vertex 450 to retain a higher level of performance than the competitors as its space is filled. This leads to better benchmark numbers in one of our benchmark suite’s most important metrics.

While some may initially question the Vertex 450’s product designation, it is without a doubt one of the SSD market’s best values. If you are looking for an enthusiast grade drive that can run with the Vectors of this world but don’t want to shell out a small fortune, the new Vertex 450 deserves careful consideration.
