It could seem onerous to fathom however a lot sooner stable state drives (SSDs) are on the horizon, with sequential learn and write speeds on tempo to double over at this time’s quickest options. In a quick demonstration posted to YouTube, Phison confirmed off an engineering pattern SSD ripping off reads simply shy of 12.5GB/s and writes exceeding 10GB/s.
Looking again, the primary spherical of PCIe 4.0 SSDs that arrived available on the market settled in with prime speeds of round 5GB/s. Then as time went on, Phison and different controller makers launched new chips that pushed speeds into 7GB/s territory, with at this time’s quickest drives exceeding that threshold by a couple of hundred megabytes per second.
The PCIe 4.0 bus helps speeds of round 2GB/s (barely much less). Modern M.2 type issue SSDs have largely adopted an NVMe x4 interface (there might be slower SATA fashions as nicely), with a theoretical ceiling of seven.88GB/s over PCIe 4.0. We’re already near that higher restrict with drives like Adata’s XPG S70 Blade pushing 7.4GB/s reads.
Enter PCIe 5.0 and next-gen SSD controllers just like the PS5026-E26. Here’s a have a look at it in motion…

In the brief 42-second video, Phison exhibits off its PS5026-E26 controller mated to an pre-production SSD geared up with 1TB of 3D triple-level cell (TLC) NAND flash reminiscence from Micron. It begins with a closeup of the drive connected to a board that is put in in a PCIe 5.0 slot, after which pivots to a sped-up benchmark run in CrystalDiskMark.
Here’s the way it fared…
The 1TB drive topped out with a 12,457MB/s sequential learn pace and 10,023MB/s sequential write efficiency, or round 12.5GB/s and 10GB/s, respectively. Those speeds will not be fairly double that of at this time’s prime performing SSDs, however they’re considerably sooner.
In the video, Phison notes that its controller and drives are constructed round them are “compatible with two leading chipset platforms.” We can take that to imply Intel’s Alder Lake and AMD’s upcoming Zen 4 platforms, each of which embrace PCIe 5.0. To that finish, Phison not too long ago introduced a strategic collaboration with AMD and Micron to flesh out a PCIe 5 ecosystem of appropriate merchandise.
“We are pleased to announce our cooperative effort with Micron and AMD to advance the technological development of PCIe Gen5 storage offerings, as this validates Phison’s commitment to upholding customer-centric values,” mentioned Leo Huang, Sr. Director, Product Marketing, Phison. “The E26 controller enables gamers to compete at the highest level and helps content creators to maximize the overall system performance to increase productivity.”
The gaming angle is a bit of overzealous in the meanwhile, as builders will not be but taking full benefit of the uncooked pace efficiency at their disposal. However, there are efforts to push builders in that course. Both fashionable era game consoles—Xbox Series X|S and PlayStation 5—make use of high-speed PCIe 4.0 storage, and Microsoft’s DirectStorage API for Windows offers a path to raised make the most of speedy storage.
Even although it’ll take a while, it is nonetheless good to see corporations pushing the envelope, provided that storage was as soon as a efficiency bottleneck (earlier than the arrival of SSDs).
