A new utility we have added to our line-up of benchmarks is the ever popular HDTune Pro. HD Tune Pro is a hard disk / SSD utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.
*NOTE*Samsung 850 Pro is 128GB model and this may reflect an unfair write speed deficit against comparable 256GB drives.
