OCZ Vector 150 Series Solid State Drives Tested

3 thumbs up

Next we ran SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and read and write performance metrics are detailed below.

Synthetic HDD Benchmarking

 

According to SiSoft SANDRA's physical disk benchmark, the new OCZ Vectors offer very competitive read speeds and writes are among the best as well. Only a few MB/s separate the top performers in this test.

ATTO Disk Benchmark

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.



We saw some odd (and repeatable) issues with the OCZ Vector 150 drives in the ATTO Disk Benchmark. With the vast majority of transfer sizes, the drives competed well with competitive offerings. In the write test especially, the Vector 150 were right in the mix. But in the read tests, the drives choked with 8K and 32K transfers.
