First, we will use some synthetic benchmarks to measure the performance of the Pyro SSD. SSDs are often difficult to compare with real-world tests because the differences between them are so minimal, and nearly immeasurable when measuring by hand. When we do real-world testing we will be comparing to a regular 7200RPM hard drive, to demonstrate the advantages of an SSD over the larger, heavier mechanical hard drives we are all so familiar with.
ATTO Disk Benchmark
ATTO is a benchmark which uses compressible data to measure SSD performance. It tests it with a wide array of file sizes, and its compressible nature helps assess the maximum potential of the DuraWrite controller present in Sandforce drives, thus why you'll see much higher read and write speeds than the AS SSD incompressible benchmarks.
We can see that the Pyro's read speed actually beat the 520MB/s performance claimed by Patriot, by reaching up to 526MB/s. The other side though is that the highest write speed seen was 412MB/s, which is a fair margin below the 490MB/s claimed performance, but still very fast nonetheless.
AS SSD is an SSD benchmarking software which uses incompressible data, which presents a challenge to Sandforce drives, or other controllers which utilize data compression. Sandforce uses DuraWrite compression and thus will not perform as well with incompressible data as it would otherwise.
A similar imbalance is also seen in the incompressible tests, with the Read speeds far outpacing the Write speeds in the sequential tests, although the write speeds do much better in the random single and 64-threaded 4K tests. 4K tests are often highlighted in benchmarks since many of the regular real-world applications run in the smaller, 4K data range.
