Phison’s next-gen PCIe 5 SSD controller is nearly twice as fast as the best PCIe 4 drives at 13.5 GB/s


One of many first PCIe 5.0 SSD controllers is already hitting 13GB/s within the labs, making the long run shiny for critically fast transfers. Phison, the makers of the E26 controller that is behind these numbers, already has samples with motherboard producers in preparation for the large rollout later this 12 months. Throw within the promise of cheaper SSDs, and Microsoft’s DirectStorage, and 2022 may effectively be the 12 months that SSDs take gaming to the following degree.

If you happen to’re down together with your NVMe SSD controllers, Phison should not want a lot of an introduction. Its E16 controller single-handedly kick-started the entire PCIe 4.0 storage push with the discharge of the AMD Zen 2 again in 2019. This E16 controller might be present in just about all of the first-gen PCIe 4.0 drives. This was adopted by its E18 controller firstly of 2021 that just about dominated the marketplace for the whole 12 months and may be discovered within the likes of the FireCuda 530, Sabrent Rocket 4 Plus, and the Corsair MP600 Professional XT.

Phison is clearly seeking to proceed this spectacular run with its E26 controller. Its full title is the PS5026-E26 and it’s designed to begin the ball rolling with PCIe 5.0 SSDs, which till now have been notably absent from the desktop enviornment, regardless of Intel’s Alder Lake supporting the usual. The headline-grabbing promote for PCIe 5.0 when it comes to storage is that it doubles the accessible throughput of the interface, as much as a theoretical most of 128GT/s, or 16GB/s. 

Phison E26 performance is looking good.

Actual-world efficiency is at all times much less, however Phison is already claiming some spectacular numbers in testing, with CrystalDiskMark displaying a learn of 13,815MB/s and writes of 12,727MB/s. For comparability, the E18-powered Seagate FireCuda 530 manages reads of seven,300MB/s and writes of seven,000MB/s. Fairly the development then. Phison says it has handed the {hardware} part, having taped out on the finish of 2020 in truth, and is now onto constructing firmware and tuning efficiency. The very fact early samples are with motherboard producers is an efficient signal although.

It is nonetheless very early days for PCIe 5.0 after all, and a few could really feel that PCIe 4.0 nonetheless hasn’t fairly delivered on its promise for remodeling gaming. There are a few causes for this, with value being an apparent issue—PCIe 4.0 are notably dearer than PCIe 3.0 drives—plus not each platform help PCIe 4.0, and the necessity for requirements to totally unlock the efficiency of provide. There’s not a lot Phison can do in regards to the final two, however with regards to pricing it does have one other controller on the way in which that might assist there. 

Phison E21T is a budget PCIe 4.0 controller

The PS5021-E21T is a PCIe 4.0 controller providing sequential reads and writes of as much as 4,800MB/s and 4,500MB/s respectively. The fascinating factor right here although is that this can be a DRAM-less providing, which ought to make for some budget-friendly drives. Samsung already has a DRAM-less drive within the type of the Samsung 980 (the non-Professional providing), and the worth of that drive makes it a tempting providing, although that is restricted to PCIe 3.0 efficiency.
