Samsung 860 Pro 1TB SATA III SSD Review

TweakTown Rating: 98%Manufacturer: Samsung



Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. With ATTO, we are looking at maximum sequential performance with compressible data as well as the performance curve.




Compressible sequential read/write transfers max out at 563/532 MB/s. Both figures meet or exceed factory specs. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity.


Sequential Write




The 860 Pro gives us what we are looking for. A nice smooth performance curve that ramps up quickly. The 860 Pro's performance curve is identical to the 850 Pro 2TB.


Sequential Read




We are looking for a nice smooth performance curve and good small-file performance. The 860 Pro gives us what we are looking for and again follows identically the performance curve of our 2TB 850 Pro.




Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4K QD16. With Anvil's, we are focused on the total score.




We consider 10K IOPS at QD1 random read a milestone that very few SSDs are capable of delivering. Only the best can do it. The 860 Pro's factory spec sheet gives a figure of up to 11K random read IOPS at 4K QD1 - we are hitting 12.6K which is a huge improvement over the 850 Pro. This is where performance matters most and is hardest to achieve, especially without an SLC buffer.






Anvil's scoring typically provides us with a good indication of a drive's overall synthetic performance. Whenever we get a score of over 5,000 we take notice. The 860 Pro sets a new lab record for SATA SSDs by delivering an astounding score of 5,877.


(Anvil) Read IOPS through Queue Depth Scale




With a partition on the drive and 75% full, we are not able to hit factory max random read specs. Close enough though. If we had a higher capacity model, we believe we could hit 100K IOPS under these same conditions.




Intel's 545s delivers better random read performance at QD1-QD2. At QD4 and higher, the 860 Pro eviscerates the competing drives in our test pool. Here we can see the huge improvement in random read performance the 860 Pro has over the 850 Series.


(Anvil) Write IOPS through Queue Scale




With a partition on the drive and 75% full, we are not quite able to hit factory max random write specs. Close enough though. If we had a higher capacity model, we believe we could hit 90K IOPS under these same conditions.




The 860 Pro delivers the best performance curve for a SATA SSD that we've seen to date. Once again, we see a significant improvement over the 850 Series.
