Ready for a hard drive speed test? Learn what are the best hard drive benchmark software and how to interpret your SSD and HDD benchmark results.
Ask any techie and chances are they will tell you that hard disk speeds given by manufacturers are often overstated or misleading (e.g. speeds attained under unrealistic scenarios).
In that case, the only sure-fire method to determine your real-world hard disk speed is to put it through a reliable hard drive performance test.
And once you have the benchmark results, we'll point out what are the numbers to look for and what they mean in plain English.
While they are all dependable hard drive benchmark tools, we recommend CrystalDiskMark over the others for the following reasons:
The 3 simple steps for running a SSD benchmark or HDD benchmark with CrystalDiskMark:
1. Choose the drive that you want to benchmark (outlined in red above)
2. Leave the number of test runs and test size at default values (number of test runs: 5, test size: 1000MB).
3. Click the "All" button at the top left and wait for the benchmark results.
Now that we have our hard drive benchmark results, let's make sense of the numbers:
The numbers that will matter to most people are the ones in the "Seq" and "4K" row (outlined in red above).
Seq is short for sequential (read/write speeds), and 4K refers to random (read/write speeds).
Sequential read/write - measures the speed of your hard drive when it comes to the transfer of large files (e.g. installing programs, copying videos, programs, photo albums or music libraries from one hard drive to another). High sequential read speeds will also shorten the loading time for large programs such as modern computer games and video editing software.
4K random read/write - measures how fast your hard drive is able to access small files that are randomly scattered across it. A hard drive with higher 4K numbers will able to multi-task better, so your operating system will be more responsive and you can run more background programs (e.g. virus shield, firewall, torrents, instant messengers etc) without any major slowdowns.
For an operating system boot drive, 4K random read speeds are the most important, followed by 4K random write speed.
For a mass storage drive (e.g. external hard drives and USB flash drives), sequential read/writes will matter more.
