HD Tune Pro - Write Tests
As with the Read Test, the Areca controller gives us a difficult time with the max and burst speeds since the controller has a cache module installed. Looking at the average and minimum speeds, we see that the MasterDrive MX is a little slower than the Samsung SATA-II on write speed.
The small dip in performance that accounted for the minimum speed really hurt the average score. Starting at the 19 MB mark and continuing through to the 28 MB mark you can see the dip. The bad thing is that it happens four times in the drives write cycle. The Super Talent MasterDrive MX uses MLC, a memory type known to have slower write cycles than SLC, the memory that the Samsung SATA-II drives uses. More on this in the conclusion.
