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.

Somehow, we lost our screenshot of the 512GB model. So, all we have to present for a screenshot is the 256GB model.

 

Sequential Write

We would like to see performance ramp up a bit faster, but we are pleased to see no large dips in performance like we see from the Intel 600p.

 

Sequential Read

Here again, we would like to see performance ramp up faster. This time we are able to hit max factory sequential specifications, unlike the previous test.

 

 

 

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.

Scoring

None of the drives in our test pool can give us our 10K, but we don't expect to see 10K from value-oriented SSDs. The SBX performs as intended, easily beating Intel's 600p at all capacity points despite a 2-lane disadvantage.

 

(Anvil) Read IOPS through Queue Depth Scale

This is the random read performance we're getting at QD32, with an OS on the drive and 75% full.

The SBX doesn't run into the same wall as the 600p does at higher queue depths. Looking at the 128GB SBX, we see it outperforming the 128GB 600p by about double at higher queue depths. In-fact the 128GB SBX is outperforming the 256GB 600p across the board.

 

(Anvil) Write IOPS through Queue Scale

This is the random write performance we're getting at QD32, with an OS on the drive and 75% full.

Here again, we see performance ramping up slowly. At QD1-2 performance is almost flat. At higher queue depths, the SBX comes on strong even beating out the SX8000 and M8SeGN.
