Phison prepares an update for her SSD controller in order to exceed the 7000 MBps, both in reading and writing.

With the inclusion of PCIe 4.0 by part of AMD in a massive way in its latest chipsets, numerous SSD manufacturers have chosen to launch units that make use of the PCIe bus in version 4.0. The improvement is obvious in terms of speeds, since the bottleneck was carried by the bus part and the controllers. The first PCIe 4.0 SSDs reached 5000 MBps using the controller Phison E 18 , while a few months later Phison released another controller, the PS 5000 – E 18, which allowed reaching the 7000 MBps in some SSDs such as the GALAX Extreme Pro or the Sabrent Rocket 4 Plus.

Phison E SSD controller 18 will allow speeds of more than 7381 MBps in read and more than 7000 MBps in write

Now, from Tweaktown we can see that they have had access to a update of said controller, the Phison E 20 , through which speeds are achieved greater than 7000 MBps both in writing and in reading. Specifically we see 7381. 21 MBps in read and 7025. 86 MBps in writing , in sequential transfers (which is how the speed of SSDs is commonly evaluated).

This leak comes right after Silicon Motion announced its new PCIe 4.0 controllers, reaching the 7400 MBps read on the highest performance model. However, in writing it is somewhat below with a not inconsiderable 6800 MBps. In this way, being 7877 MBps the theoretical limit for the bus PCIe 4.0 x4 , both controllers are already close to it , and there will be no way some to overcome it since it is a physical limitation.

With 15 years ago I started to overclock my PC to pry every extra FPS I could in gaming and scratch a few milliseconds in SuperPi, while relentlessly posting about hardware on the Geeknetic forum as a user and reader. They were probably so fed up with continually reading me on the forum that I became part of the writing team, where I continue to report on the latest in technology. Astrophysics and PC games are the hobbies that, after hardware, cover most of my free time.
