ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: So far the Patriot Pyro falls right in line with its SandForce peers on the compressible data ATTO benchmark. Compressible data is where the SandForce controllers shine and pretty much where we’ll see the peak performance numbers.
This test employs compressible data showing the best case scenario in terms of data throughput for the SandForce drives. Let’s have a look at a few others that use incompressible data to see how that impacts the scores.
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation who has since discontinued work on Iometer and it was ultimately turned over to the Open Source Development Lab (OSDL). We chose the file sizes that best reflect many of the Windows transactions. 4KB random read/writes is very common on every day user machines. Large sequential writes represent large file copies. The drive block size is 512kb so it should give a very good indication of peak performance. We set the queue depth to 4 for the tests as generally Windows operations tend to happen at queue depths of 5 or less.
Benchmark Results: The 512kb reads are a little below what we see with the other similarly equipped drives but the other sequential scores fall in line. The random read scores really stand out with a score of 219.48 MB/s that is only bested by the Crucial/Micron drive which uses similar but higher density NAND.
