Phison E12 NVMe PCIe Gen3 x4 Controller Preview

By Jon Coulter from Jun 4, 2018 @ 11:10 CDT



Version and / or Patch Used: 3.05


ATTO is a timeless benchmark used to provide manufacturers with data for marketing storage products. When evaluating ATTO performance we focus on the drive's performance curve and small-file performance.






We are able match or exceed factory sequential read/write performance specs even when we are testing as system disk 75% full.


Sequential Write




In terms of shear sequential speed, the E12 sets a new lab record. Small-file performance could be a bit better, but overall this is Tier-1 performance.


Sequential Read




The E12 trades blows with Samsung's 970 EVO for the best performance curve of the bunch. SanDisk's Extreme Pro eventually matches the E12's throughput but does so with a vastly inferior performance curve.



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.










In terms of total score, Phison's E12 delivers a new lab record for a flash-based SSD. The E12 is showing us a new level of write performance. Its write score alone is almost equivalent to the M9PeY's total score. 700K random write IOPS at QD16 is mind bending to say the least.


Looking at read scoring, we see that the E12 does better than Samsung's 970 EVO but gets edged out by the SanDisk's Extreme Pro and Plextor's M9PeY.
