ATTO Disk Benchmark

ATTO Disk Benchmark is a free benchmark that allows you to compare the performance of the solid state drive using a variety of transfer sizes. The total size of each test is limited to 256 MB, which is good enough for most intents and purposes.

I/O Comparison

In this test, we compared the basic I/O performance of the 240 GB HyperX Savage SSD.

The Phison PS3110 controller does not appear to perform data compression, but we noticed that it had a much higher read speed and a slightly higher write speed with compressible data. For some reason, the HyperX Savage was significantly slower at reading small blocks of non-compressible data off the NAND chips. It only achieved comparable performance for both compressible and non-compressible data with blocks of 128 KB or larger.

Multiple I/O Comparison

In this test, we compared the 240 GB HyperX Savage SSD's ability to handle 8 simultaneous I/Os.

	Compressible Data Set Minimum Read Speed - 24.6 MB/s Maximum Read Speed - 566 MB/s Minimum Write Speed - 26.3 MB/s Maximum Write Speed - 540 MB/s
	Non-Compressible Data Set Minimum Read Speed - 24.6 MB/s Maximum Read Speed - 564 MB/s Minimum Write Speed - 26.4 MB/s Maximum Write Speed - 545 MB/s

There was practically no difference in performance whether the data was compressible or otherwise. Whether the data was compressible or not, the HyperX Savage was able to deliver its peak performance with data blocks of 16 KB or larger.
