A friend of mine recommended a program called Crystal Disk Mark to benchmark my hard drives recently. I’ve been using a program called Everest (commercial software) and Crystal Disk Mark is freeware. I did hard drive benchmarks for random read using 4KB data size, Everest returned an average result of 41.1MB/s, whrere Crystal Disk Mark returned 0.83MB/s. I tend to think that the commercially released software is going to be the more valid result. Does anyone have any idea why these 2 benchmarks are so wildly different?
