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 gained popularity amongst reviewers. It is now considered a must have application for storage device testing.





Reading sequential data across a clean drive gave us an average speed of 412MB/s. The maximum and minimum speeds were very close to the average speed.




The sequential write speed came in at 408MB/s. Both of the sequential results are close to the Intel 520, our LSI SandForce based reference drive with 25nm NAND flash.



HD Tach - Sequential Write Performance after Random Writes




The HD Tach run comes after all six tests in HD Tune Pro. This is a check to see the sequential write speed after a liberal dose of random writes to the drive. LSI SandForce drives do well here since the compression algorithm doesn't write all of the data to the NAND. This means your drive stays fast for a longer period of time without high doses of garbage collection.
