CES 2019 - Phison lifted the veil on the company's next-generation high-performance NVMe SSD controller at CES. The upcoming PS5016-E16 controller is the first to take advantage of PCI Express 4.0 bandwidth that we hope will come to market around the March timeframe.
The E16 is the logical successor to Phison's PS5012-E12 currently shipping in products like the MyDigitalSSD BPX Pro and Corsair Force MP510. The new controller doubles the interface bandwidth by using four lanes, but with faster 4th generation PCIe technology. The controller also ushers in 4th generation low-density parity check error correction from Phison.
Phison claims 4,000 MB/s sequential reads and 4,100 MB/s sequential write speeds. Phison's CES demo already shows speeds in excess of those advertised. We may see even higher performance with retail products and some minor specification changes. At the time of writing Phison states the E12 supports flash speeds of up to 800 MT/s but next generation memory from Toshiba sports a faster bus interface speed. The faster memory would lead to higher throughput performance and lower latencies.
