ATTO

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.

Sequential Write

The 2TB 970 EVO exactly matches the 1TB model when writing sequential data of various file sizes. The 970 EVO delivers exceptional small file performance which is what we are looking for.

Sequential Read

The 2TB 970 EVO runs even with the 1TB model until we hit file sizes of 512KB. At 512KB and above the 1TB model delivers slightly more throughput.

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 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.

Scoring

The 2TB 970 EVO delivers a new flash-based lab record for total write score. However, we value read performance more than write performance and this is where we find the 970 EVO somewhat lacking.

(Anvil) Read IOPS through Queue Depth Scale

We are hitting 240,000 4K random read IOPS at QD32 with our system disk 75% full.

Here is where we begin to see a performance differentiation between 256Gbit flash and 512Gbit flash. The 256Gbit sporting 1TB 970 EVO performs significantly better than the 512Gbit equipped 2TB 970 Pro when reading random data.

(Anvil) Write IOPS through Queue Scale

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

There is very little difference between the 1TB and 2TB 970 EVO when writing random data. Both models perform well, but the SanDisk Extreme Pro takes the win, because of its superior performance at low queue depths.
