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.
The PNY Prevail won't run into any issues when working with compressible data like what HD Tune Pro uses to generate sequential read and write numbers. The Prevail 240GB averages 416 MB/s in this test. The Prevail is fast, but the new crop of next-generation SSDs show the age of the SF-2281 controller.
Then again, the SF-2281 is still a very good controller and the 25nm flash helps to keep write performance high and the latency low.
HD Tach - Sequential Write Performance after Random Writes
The LSI SandForce architecture doesn't write all of the incoming data to the flash. That means your SSD will perform as if it just came out of the box longer. Here we see the sequential write speed after a reasonable amount of random writes to the drive.
The write performance stayed reasonably high, only dropping under 250 MB/s a few times and never less than 200 MB/s.
