HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.





The Crucial m4 128GB comes out of the gate looking good. The sequential read grouping is very tight with the maximum and minimum speed very close together. The average speed is 375MB/s which is very good no matter what you compare it to.




The sequential write speed group is also very tight, but as you can see here writing data is where the m4 has issues. This issue was more profound on the 128GB C300 and Crucial has increased the write speed on the m4. We'll have to see how this affects real world performance.
