HD Tune Pro - Sequential Performance


Version and / or Patch Used: 4.55




We recently revamped out charts, after this review the MX100 will replace the M500 in all of our capacity size charts. We recorded the MX100 256GB at 453.1 MB/s sequential read speeds while reading across the entire LBA range. Most modern SSDs score very well when reading sequential data though, as the chart shows.




Scoring well when writing sequential data is another story. The Crucial MX100 scored just over 300 MB/s when writing sequential data across the LBA range. This is a 100 MB/s improvement over the M500 in the same test, but 27 MB/s slower than Crucial's M550.



HD Tach - Sequential Write Performance after Random Writes


Version and / or Patch Used:




After a reasonable number of random reads and writes, we ran HD Tach to view any issues with write performance fall off. The MX100 256GB does well in a majority of the tests, but towards the end, very clearly we see where the dirty flash is.
