SSD Performance Atto Disk Benchmark
Atto Disk Benchmark
One of the finest tools available to measure storage performance is ATTO. I love it to death as it is so reliable and produces such accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a 32 MB sequence of 4 KB files, yet also 32 MB in 1 MB files. This gives us an excellent scope of overall performance with small and large files. But let's have a peek at actual performance. I threw in a couple of comparable SSDs and a Western Digital Velociraptor HDD. We scale 4 KB block sizes to 1,024 KB block sizes in bursts of 256 MB with a queue depth of 10 and then measure how fast the storage device is dealing with them.
