HD Tune Pro gives us accurate read, write, and access time results and, over the last couple of years, has gained popularity amongst reviewers. It is now considered a must-have application for storage device testing.
The chart shows what we've known for some time; with a file system on the drive and overhead, we've hit the limits of SATA 6Gb/s with sequential performance. The Crucial M550 1TB delivers 454.6 MB/s sequential read on average in HD Tune Pro.
Write performance is where modern SSDs fall short. When the flash isn't in an optimal state, the drive slows when writing data. On average in HD Tune Pro, we scored 345 MB/s in the sequential write test.
HD Tach - Sequential Write Performance after Random Writes
After a light random workload in HD Tune Pro, we ran HD Tach to see how well the M550 held up. HD Tach uses 128KB to test sequential performance. Here we see that both read and write performance leveled off at around 250 MB/s.
