The difference between 5 and 3.5 watts doesn’t sound like much (especially next to 350 watt CPUs and GPUs), but it is actually a big difference for SSDs. Even the fastest PCIe 5.0 SSDs using Phison E26 controllers max out at 12 or 13 watts, and that’s enough to require an active cooler. Shaving an extra 1.5 watts off could make passive cooling more feasible for top-end PCIe 5.0 drives, though a good passive cooler would likely still be required. Slower 12GB/s and 10GB/s SSDs might even run just fine under motherboard-included heatsinks if they can get under 10 watts with the SM2508.

Unfortunately, Silicon Motion said we could only expect SM2508-powered SSDs in 2025. That’s at least a full year from now, and considering 14GB/s SSDs using Phison’s upcoming controller might even come out before 2023 is over, the SM2508 could be really late to the party. Of course, if Phison hasn’t improved power consumption by then, Silicon Motion might still have a decent advantage. After all, it’s almost universally agreed that active cooling for SSDs isn’t all that desirable.
