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.

We are able not able match factory sequential read/write performance on either capacity point when the drive is 75% full. Keep in mind that factory sequential speeds are measured at QD32, we are running this test at QD4.

 

Sequential Write

The performance curve looks really good when writing sequential data in burst mode. The 1TB model manages to outperform Samsung's mighty 960 Pro 2TB. The 512GB model does the same to Samsung's 960 EVO 1TB. Challenging Samsung's finest right out of the gate is indeed impressive.

 

Sequential Read

Sequential read performance ramps up slowly. Not as slowly as the Intel 750, but slower than we would like to see. However, as you will see this is one of the few faults we can find with the M9Pe.

 

 

 

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 the 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

In terms of total score, the M9Pe shreds everything except for the 960 Pro and EVO. Now when we dig a bit deeper and look at the all-important read score, both drives are outperforming the 960 EVO by a considerable margin.

 

(Anvil) Read IOPS through Queue Depth Scale

Random performance is much more important than sequential performance for a system disk. Low queue depth random performance is more important than high queue depth performance. With those two previous statements in mind, the results of this test are quite impressive. The M9Pe is beating the 960 Pro when reading buffered random data at low queue depths.

Random write performance is middle of the road when data is on the drive. However, it is reaching elite status at QD16 and higher.
