OCZ Vertex 450 256GB SSD Review

Specifications, Pricing and Availability




The new OCZ Technology Vertex 450 has three capacity sizes - 128GB, 256GB and 512GB. These are also the same capacity sizes found on OCZ's other in house controller product, Vector. At this time, we have the 256GB capacity size and plan on reviewing the 128GB and 512GB capacity sizes post-Computex.


The performance for the two largest capacity sizes comes in just a hair under Vector, but the 128GB model has a 110MB/s sequential write performance difference. This is due to the new 20nm NAND flash and it's expected since 20nm flash lacks the same high levels of flash interleaving because of the increased density.




The 256GB capacity size reads sequential data at 540MB/s and write sequential data at 525MB/s. 4K IOPS at QD32 comes in at 85K read and 90K write. All four-corner metrics come in just under those of Vector in this capacity size, but the trade-off in performance comes with three big benefits. The first is power consumption. In our testing, we found Vertex 450 consuming quite a bit less power than Vector. The second major benefit can be linked to the lower power consumption, low heat output. The third benefit is price. Let's cover that one now.


In our own in-house product spec sheet we included the official OCZ Technology MSRP list for Vertex 450. The 256GB capacity size wasn't low enough to make our best SSD's under $200 Editorial, but Vertex 450 ships with a real accessory bundle. In the package you get a desktop adapter bracket, drive cloning software (Data Migration), mounting screws, a sticker and a paper manual. We clump the warranty in with the accessory package so we can't say this product is on the same plane with Vector, since Vertex 450 only ships with a three year warranty instead of five.
