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. It is now considered a must have application for storage device testing.





HD Tune Pro uses compressible data, we'll look at incompressible data later in the review. With 64KB blocks, the SX300 256GB does really well reading data across the span of the drive.




Writing compressible data going across the span of the drive the SX300 has no problem writing above 400MB/s.



HD Tach - Sequential Performance after Random Writes




After a consumer appropriate amount of random writes to the drive, we ran HD Tack to see performance loss with sequential writes. The SX300 256GB drops down to just less than 150 MB/s in a few places.
