AMD Radeon R7 Series 240GB SSD 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 AMD Radeon R7 Series 240GB SSD finished just behind the leader in SANDRA's Physical Disk benchmark, just missing the pole position but a couple of megabytes per second.
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 weirdness with the AMD Radeon R7 Series 240GB SSD. At a couple of block sizes, in both the Read and Write tests, the drive's performance dipped slightly. We say similar anomalies with the recently released OCZ ARC 100 as well, which leads us to believe is something funky with OCZ's more recent firmwares.
