Phison is working on a new controller intended for next-generation solid-state drives using the high-speed PCI Express 4.0 interface. A key feature of this innovation will be the support for higher data transfer speeds of up to 6500 MB/s.
Earlier this year, Phison showcased its PS5016 controller designed for next-generation solid-state drives capable of connecting via four PCIe 4.0 lanes. This controller enabled the creation of solid-state drives with an impressive read speed of 5000 MB/s. Similar innovations were exhibited at the recent Computex 2019 by many manufacturers, including , and others.
During Computex 2019, Phison's CEO, Pua Khein-Seng, stated that "the best is yet to come." He meant that faster controllers for drives with the PCIe 4.0 interface are on the horizon. He promised that in the first quarter of 2020, Phison plans to release a controller capable of providing data transmission speeds of 6500 MB/s. This is nearly twice the speed of most high-performance M.2 NVMe solid-state drives with PCIe 3.0 x4.
It is worth noting that the theoretical maximum bandwidth of four PCIe 4.0 lanes is 8 GB/s. However, such speeds are not achievable in practice, just as the theoretical 4 GB/s is unattainable with the PCIe 3.0 x4 interface. The fastest PCIe 3.0 x4 drives, like the Samsung 970 Pro, reach up to 3500 MB/s. Therefore, we can assume that devices with the new PCIe interface will achieve approximately double that speed, around 7000 MB/s.
Thus, the upcoming Phison controller with its 6500 MB/s will be quite close to maximum performance levels. It is also noteworthy that Phison is currently a leader in adopting the new PCIe 4.0 standard. Samsung has yet to make any announcements regarding plans for drives with PCIe 4.0, while Micron has promised to release SSDs with the new interface by the end of this year.
