OCZ Vertex 4 128GB review

4. ATTO Disk Benchmark

The next software we used was the ATTO Disk Benchmark. The tool measures storage systems performance with various transfer sizes and test lengths for reads and writes. The benchmark performs file transfers ranging from 0.5 KB to 8192 KB. ATTO can be adjusted to do overlapped I/O, in a variety of queue depths. We tested the SSD using the benchmark's default settings, using 256KB file length performance and QD4. ATTO probably gives the most accurate results for compressible read and write data.

 

For this test we're still using QD4. This means that our maximum read and write speeds could be a little different than OCZs, but still close. In the write test we reached over 380MB/s in several of the block sizes, mainly bigger than 32KB. The read test was very close to the claimed 550MB/s - our max was 548MB/s with 4MB and 8MB files.

The Vertex 4's sequential read speed is higher at high queue depths and larger transfer sizes.With files smaller that 16KB the drive is slow at reading as you seeing the graph below:

 

However, the drive is extremely fast when writing these small files:

Going further to larger file transfers confirms out previous findings. Still the Vertex 4 128GB drive is not the fastest you can find during reading but delivers a great performance in the writing tasks:
