Specifications, Pricing and Availability
OCZ's new Vertex 460 replaces the 450 model we reviewed May last year. The capacity sizes are the same - 120GB, 240GB and 480GB. OCZ used the same M10 version of Barefoot 3, but the flash is now from Toshiba, a move we applaud. Toshiba's 19nm MLC flash uses 64Gb dies and is considerably faster than IMFT's 20nm with 128Gb dies in lower capacity SSDs. OCZ claims sequential read performance for the 240GB model at 540 MB/s. The sequential write performance is 525 MB/s and 4K IOPS comes to 85K read and 90K write.
OCZ put together a nice slide showing the feature list for the Vertex 460. Some of this we'll cover in the next slide. OCZ again used the alloy case for Vertex 460, so the drive has a 7mm z-height. Internally, the drive has 256-bit AES encryption, but does lack eDrive and TCG Opal support.
Here we see the current OCZ 2.5" product line up. Vector 150 recently replaced the original Vector, uses the Barefoot 3 M00 controller, and pairs it with Toshiba 19nm Toggle MLC rated for 50GB per day of data writes to the flash. Vertex 450 and Vertex 460 both use the slower clocked Barefoot 3 M10 controller. The difference between these two drives is that the new 460 uses parent company Toshiba 19nm MLC, and the 450 used IMFT 20nm flash. The new 460 model has a higher performance specs sprinkled here and there.
OCZ's Vertex 460 is very close to Vector 150 performance wise, but the warranty drops to three years for 460 and the endurance rating is 20GB per day.
OCZ checked all of the right boxes for performance and now we get to look at the price. OCZ claims MSRPs of $99.99, $189.99 and $359.99 for the three capacity sizes. We compared the kit prices from Samsung's 840 EVO and found that OCZ cut the current 840 EVO prices by $10 in the two smaller capacity sizes and $20 in the 512GB class drive.
Essentially, OCZ is selling the 460 with a full retail accessory package for the same price or below what Samsung sells a bare 840 EVO in the same capacity class.
