Crytal Disk Mark - Is it accurate?

By MyLittleMansAnIdiot ·
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?

It could be the size of the file you are using here

Only being 4KB wouldn't involve the Cache on the HDD at all and it would be reading the Actual Time to read/write the file.

Where as the other one may be coping larger files and relying on the Cache of the HDD.
