OCZ Technology Vertex 3 240GB Retail Solid State Drive Review - Benchmarks - CrystalDiskMark

Our first 240GB Vertex 3 in-house was a pre-production unit with early firmware that left it slower than the 120 model we looked at later. We now have the retail 240 in and are even more impressed.

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.

In this test we're looking at 4K reads and how the drive scales when commands are stacked up with Native Command Queuing. The 240GB Vertex 3 shows a massive improvement over the 120GB model when commands are stacked 32 high. Both Vertex 3 drives perform about the same with a single 4K write and when you look deeper into the chart you can see that the Vertex 3 is faster at this task than any other SATA 6G drive on the market.

The 240GB Vertex 3 is able to scale much better when write commands are stacked. Here we see that with 32 commands the larger drive is able to write at nearly 100MB/s faster. At first we didn't believe what we saw and went back to retest the 120GB Vertex 3, but the results were the same. The 240GB drive is quite a bit faster at this task.
