One of the biggest differences between the controller that KIOXIA already introduced last week and the one that Phison has now introduced is the maximum achievable speed, since KIOXIA announced that its controller could handle speeds of up to 14 GB / s, while the Phison E26 is capable of reaching 16 GB / s, further extending the performance benchmark that we can achieve with the new revision of the standard.
Phison E26, the 5th generation of SSD controllers from the manufacturer arrives
Compared to the current PCIe 4.0 standard, the fifth revision of the standard will double the theoretical speed. With the E26 controller, Phison reaches the fifth generation of these chips and will be the first from the manufacturer to support PCIe 5.0, offering – according to the manufacturer – up to 16 GB / s of maximum speed (another thing is that later the manufacturers of SSD can take advantage of this ability).
According to Phison, consumers are still not close to reaching the maximum speed that PCIe 4.0 can offerBut they hope that manufacturers will prosper better thanks to the capabilities that version 5.0 can offer. They also assure that it is an excellent opportunity, because we will not see the first PCIe 5.0 SSDs until we have already verified the true potential of Intel’s Alder Lake platform (this of course is questionable, since we will not be able to know its true potential without SSD that are at the height).
In any case, the company has announced that they already have the first functional E26 chip, manufactured with a 12 nanometer lithography, and hope to have their custom solutions with this controller ready from the second half of 2022.
When will the first PCIe 5.0 SSDs arrive?
Although Alder Lake, the platform that will debut the PCI-Express 5.0 interface for the first time will arrive at the end of this year, it will not be until second half of 2022 when we will have the first SSDs that take advantage of it ready. And it is that all manufacturers (including KIOXIA, Marvell or Silicon Motion) have established 2022 for the launch of their respective controllers for PCIe 5.0 SSDs, but now Phison has been the one who has given a little more concrete data: in the second half of the year (from July to December).
This means that despite the fact that when Intel kicks off its new generation (and AMD will not take much longer, all is said), there will still be no SSD on the market that can take advantage of the enormous bandwidth that this new one gives. interface, so initially we will have to settle for the current PCIe 4.0 SSD that move around 7,000 MB / s speed.
In the second half of next year, we will begin to see the first SSDs with a PCIe 5.0 interface powered by the new generation controllers from the usual manufacturers and, sadly, for now we have no clue as to what price they will arrive at. They will undoubtedly be extremely fast SSDs considering the performance figures that they have given on the controllers, so it will not be uncommon to see devices that reach 16 GB / s as Phison promises. This means that, in all probability, they will be much more expensive than the units we have now on the market.
