i wanna know its temps during load as thats been issue w/ gen 5 drives as you need a decent sized cooelr just to keep it from throttling

This is just the controller, not the whole drive.
And its at least a year away.

32TB client PC ssd's! Pull the other one it yodels. Who's going to drop $3-4K on a 32TB drive if it did eventuate. We can't even get affordabe 8TB drives outi=side of a few crazy sales on older drives.

While it's not as fast as this will be the E31T should give you some insight because I believe that was the first controller manufactured on a "7nm" node (definitely Phison's first). I suspect that any decent heatsink should cover E28 based drives for normal workloads, but I'd bet it will need a big heatsink and/or some form of direct airflow for write heavy/mixed long term workloads.

Its all about the controller - max storage size, speed, and TRIM. Phison needs to bump up the date as 2026 is a year away. But then that would kill competition.

That's why instead of a single PCIe 5 M.2 slot, I'd rather have 4 PCIe 3 with the same total bandwidth. PCIe 5 speeds are only useful for, as youtuber Buildzoid puts it, file copying enthusiasts. No software can really process 12 GB/s of data inflow. And the important metric - IOs at small size low queue depths is basically the same. So I'd rather have more slots that I can fill incrementally with best price/capacity SKUs, rather than splurge for a single humongous drive at 2-3 times price/GB.

The situation with PCIe lanes has been getting worse in the recent years. And it's the biggest reason why I lament the demise of the HEDT platforms. The second off-the-cpu NVMe in AM5 is a step in the right direction but the boards ar atrocious with often only having 2 PCIe slots, and the GPU one is with 4 slot spacing because everyone can afford a 4090. But I digress..

This isn't a year away. We are looking at much sooner than that. Not tomorrow, but much sooner.
