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 exceeding factory specs by a significant amount when reading sequential data. We are getting 1000 MB/s when writing sequential data, which is 100MB/s slower than factory specs.

 

Sequential Write

Phison sees the E8 as competing directly with Intel's 600p and Western Digital's Black series NVMe SSDs. It is easy to see that the E8 has the upper hand when writing sequential data, even though the E8 is a 2-lane SSD. It is important to keep in mind that the competing NVMe drives in our test pool have the advantage of two extra PCIe lanes.

 

Sequential Read

We would like to see sequential read performance ramp up a bit quicker, but it is still better than we are seeing from the 4-lane WD Black. The E8 overtakes the SX8000 at 32KB transfers and delivers a far superior performance curve from there on up. Here we see the E8 delivering roughly 3x the performance of SATA.

 

 

 

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.

Scoring

The E8 doesn't give us our 10K, but that marker was established with 4-lane NVMe SSDs in mind. Digging a bit deeper we see the E8 outperforming the 600p and the WD Black which is accomplishing Phison's goal.

 

(Anvil) Read IOPS through Queue Depth Scale

With a partition on the drive and 75% full this is what we are getting at QD32.

The E8 is beating the SX8000 and 600p across the board and is also able to surpass the WD Black at queues above 32.

 

(Anvil) Write IOPS through Queue Scale

200K IOPS at 75% full is pretty impressive.

QD1 is where performance matters most and we find the E8 beating all but the M8SeY at QD1. At mid-range queues, the E8 falls behind, but comes on strong and leads the test pool at QD32 and higher.
