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
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.
Looking at sequential performance a difference way, it's no surprise the BP4 achieves a higher peak sequential read rate.
With ATTO we see different sized writes, but in HD Tune Pro we write to the entire span of the drive. This tells us a different story and not one that I expected to see. The BP4 keeps a much tighter group in the first write test across the span of the drive.
HD Tach - Sequential Write Performance after Random Writes
It may seem excessive until we look at the results, but this is the third sequential write test. This test runs after a number of random writes to the drive. We learned in this test that write performance can dip to less than 50MB/s.
