HD Tune is a Hard Disk utility which has the following functions:


Benchmark: measures the performance
Info: shows detailed information
Health: checks the health status by using SMART
Error Scan: scans the surface for errors
Temperature display


HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.





In HD Tune we get to see the performance across the drive. The single drive is able to deliver a maximum speed of around 118MB/s, but that dips to 55MB/s at the slowest point on the platters, leaving a 93MB/s average transfer speed. The RAIDed trio does much better; here we see RAID 5 averages 215MB/s and RAID 0 goes up to 268.3MB/s.




The write performance is nearly identical to the read performance. Here we see the single drive averaging 92.4MB/s and increasing very well as drives are added to an array.
