Phison S11 SSD Preview: Toshiba BiCS TLC & Micron 3D MLC

Version and / or Patch Used: 5.0.2


CrystalDiskMark is disk benchmark software that allows us to benchmark sequential and 4K random performance with accuracy.






Like we saw with Anvil's, the BiCS-powered drive delivers superior read performance, and the Micron-powered drive superior write performance. The BiCS-powered drive delivers a milestone 42 MB/s 4K read performance. This is a milestone for Phison because this is the first time any Phison SATA SSD has been able to exceed 10K 4K QD1 read IOPS or even get close. It's incredible performance for a DRAM-less two-channel SSD.


The 4K write performance of the BiCS-powered drive is being held back by a whopping 50% by Windows 10 as we will see when we switch to Server 2008 for our Maxed Out Performance (MOP) testing. This is likely due to a bug in the ES firmware. The Micron-powered drive doesn't suffer the same drastic 4K write performance drop with Windows 10 as does the BiCS-powered drive.

AS SSD determines the performance of SSDs. The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read/write performance of the SSD.






AS SSD is a demanding test, and both drives handle it well. We feel that a score of 1,000 plus separates high performing SSDs from low performing SSDs. Both drives deliver a score of over 1,000 points. The BiCS-powered version handily outperforms the Micron-powered drive with a blistering score of over 1,100 points.
