HD Tune Pro - Sequential Performance
Version and / or Patch Used: 5.50
After measuring sequential read performance with a 64KB block size, we see that the 850 EVO is right on the heels of the 850 Pro 1TB model. Most of the drives perform really well in the large block size sequential test; the Corsair Neutron XT is the exception, but performs much better with 128KB blocks.
Write performance separates mainstream SSDs from the top performers. At the 1TB capacity, most drives manage to deliver very high sequential write performance thanks to the increased parallelization writing to more than one NAND die at a time. Again, the 850 EVO is right on the heels of the 850 Pro, and is faster than the 840 EVO.
HD Tach - Sequential Write Performance after Random Writes
Version and / or Patch Used: 126.96.36.199
Here we see sequential reads and writes at the 128KB block size after a reasonable number of sequential and random writes to the 850 EVO 1TB SSD. The write performance doesn't take any large dips in write performance like we see with some products.
