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.

OCZ artificially limits the single queue depth reads and writes so one task can't monopolize the entire bandwidth. This gives the user additional throughput to do two or more tasks at once and the drive will always feel fast. It's a bit like the early dual-core processors when multitasking. It's because of that though, the performance in this benchmark doesn't look all that impressive. We'll use CDM later in this review to see a threaded sequential read and write test.

The single queue depth sequential write dips down, but for a different reason. The Vector 150 peaks at 451 MB/s, and that's very close to the record set by the original Vector.

 

 

HD Tach - Sequential Write Performance after Random Writes

Here we see sequential reads and writes after a reasonable amount of random writes to the drive. Write performance dips down to 150 MB/s in some spots, but TRIM and garbage collection will increase the drive's performance after an idle session.
