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.
We tested three pairs of drives with the same settings, minus the additional over provisioning, on the same system. The Vector array was at a disadvantage from the start since the capacity size was half of the Seagate 600 and Mushkin Chronos DX arrays. As a single drive, Vector is faster than both of the other drives used in the other arrays, even in this capacity size so we're not too worried about an advantage due to capacity.
Putting that into practice, the Vector array runs with the larger, more expensive arrays when reading data.
This chart is a bit misleading when it comes to the Vector arrays minimum and average performance. OCZ was the first to program in a SLC layer for writing data to the drive. SanDisk, Toshiba and Samsung have since followed suit, but OCZ was the first that we know of.
In this test where we write to the entire span of the drive, we hit some artificial performance modes that you wouldn't see under normal use.
HD Tach - Sequential Write Performance after Random Writes
In this test, after a realistic number of random reads and writes to the drive, we see one of the limited modes kick in.
