TweakTown Rating: 99%Manufacturer: Western Digital


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.



Both drives on both platforms are able to attain factory max sequential performance specifications despite this test running at only QD4.

Sequential Write


Both drives on both platforms come out of the gate swinging hard; delivering the best sequential write performance we've seen to date from a consumer SSD. New lab record.

Sequential Read


Maximum sequential performance is very good; however, we would like to see a better performance curve.

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.





In terms of total score, both drives on both platforms set new lab records for flash-based consumer SSDs. However, Samsung's 960 Pro still retains the crown for overall synthetic read performance.

(Anvil) Read IOPS through Queue Depth Scale



Only the 960 Pro is able to deliver better random read performance at QD32.


The Plextor M9PeY and the Samsung 960 Pro both deliver a better performance curve than we are getting from our test subjects.

(Anvil) Write IOPS through Queue Scale



Random write IOPS at QD32 with a partition on the drives easily surpasses factory specs which are given at QD256.


Overall, both of our test subjects are delivering the best random write performance we've seen from any consumer flash-based SSDs. New Lab record.
