SanDisk Extreme II SSD Review

Article Index:   

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.

SiSoft SANDRA 2012
Synthetic HDD Benchmarking

All three of the SanDisk Extreme II drives we tested put up some excellent scores in the Read portion of this benchmark, which positioned all of the drive at (or near) the top of the chart. Write bandwidth was also very good for the 240GB and 480GB drives. The 120GB drive can't offer the same kind of write bandwidth as the higher capacity drives, but it still performed very well.

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 three SanDisk Extreme II drives we tested once again posted some excellent scores. The 240GB and 480GB Extreme II drives consistently performed alongside some of the fastest drives we've tested, in both the Read and Write portions of the benchmark. The 120GB drive also put up some nice scores in the Read test, but its write performance fell somewhere in the middle of the pack.
