Phison E7 NVMe PCIe FW 2.1 SSD Performance Preview

By: Jon Coulter | SSDs in Storage | Posted: Sep 12, 2016 12:00 pm

NOTE: All benchmark screenshots are empty secondary volumes. We are not providing any comparison charts for this test because write transfer rates have substantially increased with Windows 10 Anniversary Edition. This increase in write transfer rates is due to a relaxing of Windows power mode switching in Anniversary Edition. This is something that has plagued Windows since the introduction of Windows 8. We are very happy to see the issue remedied with Windows 10 Anniversary Edition.



DiskBench - Directory Copy


Version and / or Patch Used:


We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) composed primarily of incompressible sequential and random data as it's transferred from our 1TB Toshiba RD400 PCIe NVME SSD to our test drive. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive's read transfer rate. Our system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.




Write Transfer Rates






Write transfer rates are double what we were getting with Windows 10 build 10586. This is what we get from Windows 7 and Server 2008 R2 - as it should be. We verified this with Samsung's SM961, and we went from a 624 MB/s transfer rate to 1188 MB/s. We will be making new write transfer rate charts for Windows Anniversary Edition as best as we can considering we do not have all of the drives on our charts in the lab any longer.



Read Transfer Rate






The E7's with 2.1 firmware deliver blistering fast read transfers. Although not charted, the E7's are second only to the RD400 and SM961 in read transfer performance.
