Phison PS5031-E31T 2TB Technical Preview (E31T Controller)

Read Throughput

In our read-throughput test, the drive peaked at the 16MB block mark at 7,540.25MB/s, nowhere near the official maximum figure of 10,300MB/s. One thing to notice is that the performance curve of the E31T is so much smoother than any other Gen 5 drive tested here.

Although the E31T throughput test result is nowhere near the official rating, it does keep it in touch with the majority of the 10GB/s drives on this list.

Write Throughput

In the write throughput test the drive peaks at 8,339.39MB/s at the 8MB block mark before dropping back to finish the test run at 7,275.50MB/s.

That test result of 8,339.39MB/s is just 261MB/s short of the official rating but still only good enough for the last spot on the graph.
