Samsung 970 Pro 1TB M.2 NVMe PCIe SSD Review

TweakTown Rating: 100%Manufacturer: Samsung



Version and / or Patch Used: 3.05


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. When evaluating ATTO performance we focus on the drive's performance curve.




We are able to attain factory max sequential performance specifications despite this test running at only QD4.


Sequential Write




This is a hard one to call, but we will give the win to the 970 EVO because it ramps up a little faster than the 970 Pro.


Sequential Read




The 970 Pro 1TB delivers the best sequential read performance curve for any flash-based SSD we've ever tested. Most vertical performance curve, great small file performance and highest throughput are delivered by the 970 Pro. Lab record.



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. When evaluating performance with Anvils, we focus on total score. When evaluating NVMe SSDs we are typically looking for a minimum total score of over 10K. We place a greater importance on read performance than write performance.








One benchmark, three lab records for a flash-based SSD. The read score is the most impressive ever for a flash-based SSD. The 970 Pro takes the Anvil's performance crown from the drive it is replacing. Lab record.


(Anvil) Read IOPS through Queue Depth Scale




We are hitting 350,000 4K random read IOPS at QD32 with our system disk 75% full.




As we've stated over and over, the most performance important metric for consumers is random read and the 970 Pro serves it up far better than any flash-based SSD in the world. Lab record.


(Anvil) Write IOPS through Queue Scale




At QD32 with a partition on our drive and 75% full we are able to easily surpasses factory specs which are given at QD128.




This is lab record for highest IOPS. However, we value low queue depth random performance more than high queue depth performance. Even though this is the best performance curve we've seen from a Samsung SSD, it's not as good as we are getting from SanDisk's Extreme Pro.
