OCZ Vertex 450 256GB SSD Review - Benchmarks - CrystalDiskMark

OCZ Vertex 450 256GB SSD Review

The rapid drop in 25nm flash availability and slow ramp up of 20nm production puts OCZ in a tough position. Vector availability is about to get scarce and Vertex 3.20 can't be profitable at less than $1 per GB. OCZ needs a higher profit product with the flash available today and it has to be faster than SandForce to sell, enter the new OCZ Vertex 450. (NASDAQ:OCZ)

CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.

 

Key Features:-

 

* Sequential reads/writes

* Random 4KB/512KB reads/writes

* Text copy

* Change dialog design

* internationalization (i18n)

 

Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.

Looking at 4K performance from the throughput side, Vertex 450 256GB manages just over 25MB/s. The drive scales well in this test and again lags just behind Vector.

The single queue depth 4K write is just behind the Vector, but there isn't anything else on the chart that can beat the Vertex 450 256GB at this task. The QD4 test is nearly as fast as the Seagate 600 SSD's QD32 result.
