Intel SSD 2500 Pro 240GB Solid State Drive Review
SANDRA and ATTO Disk Benchmark
Next we ran SiSoft SANDRA 2014, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on unformatted drives and read and write performance metrics are detailed below.
The Intel SSD 2500 Pro 240GB drive put up competitive read performance in the SiSoft SANDRA physical disk test, but it trailed the other drives in the write test.
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.
The Intel SSD 2500 Pro 240GB drive actually outperformed the other drives we tested in the important small-transfer tests and it wasn't until hitting the 32K - 64K block sizes that performance leveled out and settled in right in the same range as the competition.
