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 560/535 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.
Both SSDs perform almost identically which is to be expected because they are identical hardware configurations. Any deviation from one another is by chance more than anything else. At a 64KB or larger transfer size, both drives are running at the top of the pack. Compared to the planar-flash based WD Blue, the new 3D model delivers significantly better sequential write performance.
We are looking for a nice smooth performance curve and good small-file performance. Both drives give us what we are looking for.
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, and both drives have no problem doing so.
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. Both the Ultra 3D and the Blue 3D give us something to take notice of - and then some. Of the drives in our test pool, only the 850 EVO does better. The scoring of both of our test subjects would be significantly higher if the sequential read performance was better. This seems to be an anomaly with Anvil's benchmark.
(Anvil) Read IOPS through Queue Depth Scale
With a partition on the drives and 75% full, neither the Blue 3D or the Ultra 3D are able to hit factory max random read specs. Close enough though.
Intel's 545s delivers better random read performance at low queue depths. Overall though, both the Ultra 3D and the Blue 3D deliver stellar performance that is as good or better than any of the SSDs in our test pool.
(Anvil) Write IOPS through Queue Scale
We are able to hit factory max random write specs (84K IOPS at QD32) even when the drives are 75% full.
The Blue 3D and Ultra 3D both deliver a huge performance increase over their planar sibling; the WD Blue. In terms of performance against the contenders in our test pool, the Blue 3D and the Ultra 3D deliver middle of the road random write performance.
