The 4TB version is only a Gen 3×4. It won’t reach this performance. Stay tuned for our report within the next week or so… and then maybe the 8TB after that.

I too would prefer to max out the PCIe 4.0 and have a newer controller (and NVMe version), fortunately I won’t be buying until next year.

Computex has been delayed until September 2020. So I would expect wider availability only in 2021.

Heat shouldn’t be too bad, they are dropping down from the 28nm process to 12nm. That alone should help a lot with managing power consumption. and ultimately heat. Just look at the leap in efficiency AMD got over Intel. Next-gen products just may make Gen4 SSDs a viable upgrade.

Update… Just spoke with Chris at Phison who says they were hoping around Computex which would be next month or so. It would then be a bit later as manufacturers got it up for sale.
