Phison launches the first ever SSD controller to have built-in AI processing, along with some monstrous random data performance figures
May 20, 2025
It probably won't appear in any gaming PC. Well, not yet, at least.
When it comes to the world of PC gaming, a new SSD controller chip is unlikely to garner many headlines, as it's normally the solid state drives they're used in that are more newsworthy. But at this year's Computex event, SSD specialist Phison announced a new controller that is faster and more power efficient than the competition, and even has integrated AI processing to speed up…well…AI processing.
The controller in question is the rather unassumingly titled E28, and it's already picked up an award at Computex for its innovation. Manufactured on TSMC's N6 process node, Phison says the E28 sports random read/write rates of 2,600K and 3,000K IOPS, respectively.
To put those figures into perspective, the best gaming SSD, the new WD Black SN7100, only goes up to 760K and 1,200K IOPS in each case.
Even compared to Phison E31T, its best consumer-grade SSD controller, the figures are still mighty. That little chip, shown above in the Corsair MP700 Elite, can reach random read/write rates of 1,500K and 2,200 IOPS. The E28 makes it look positively slow.
Phison also claims that the E28 controller uses 15% less power than other 6 nm SSD controllers, although it doesn't specify which others it's comparing the new chip to. Either way, less power means less heat, and that's good news all around when it comes to ultra-fast storage.
