The new Phison PS5028-E28 is a Gen5 SSD controller unveiled at CES 2025, with the new flagship Gen5 SSD controller made on the TSMC 6nm process node, with capacities of up to a huge 32TB, and read and write speeds of up to 14.5GB/sec, with up to 4200 MT/s flash transfer rate.

Phison says its new Gen5 SSD controller has random read and write performance of up to 3000K IOPS, with power consumption of just 8.5W average. Phison explains the PS5028-E28 as the "world's fastest consumer SSD with up to 14.5GB/sec sequential read and write performance. Synchronous random performance at 3M IOPS read and write. 8.5W average power consumption, no heatsink required".

Now, Phison says that no heatsink is required but at least admits that the heatsink is not required, but recommended for workstation and sustained loads. If you're gaming on the new Phison PS5028-E28 Gen5 SSD, then a heatsink wouldn't be required, but if you're pumping 14.5GB/sec for hours and hours under sustained workstation-style loads? Yeah, you'll need a heatsink.
