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 Samsung 840 delivers a big dose of low queue depth sequential read performance. It's not just out there; it's way out there - over 30 MB/s faster than the Neutron GTX.

Then we get to the sequential write performance and it isn't as impressive. Just yesterday we saw the new OCZ Vector SSD deliver just 350MB/s average sequential write speed at QD1, but it managed to make up for the low performance by having exceptionally low access time.

 

The Samsung 840 is handicapped by TLC flash that has higher latency than MLC flash, a recovery from access times is unlikely, but let's take a look and find out.
