Installed the PNY XLR8 CS3040 1TB M.2 NVMe Gen4 (on sale $156.99). Heatsink I purchased separately from Amazon. Don't purchase the version that comes with heatsink because it's too big.

Edit: read speed 5636.468 MB/s

Also transferring games back to PS5's built-in HD was slower. Faster transferring to NVME

Anyways if you are low on cash the NVME works. Link: https://www.amazon.com/PNY-CS3040-Internal-Solid-State/dp/B08KGXVXGM/ref=mp_s_a_1_3?dchild=1&keywords=PNY+XLR8+CS3040+1TB+M.2+NVMe+Gen4&qid=1627759703&sr=8-3

Now for the heatsink I went with this one for $9.99;

I will let everyone know if there are any problems that arise.

Wow good work, I'm sure it'll help out others. 👍

And just so you know I'm using the PNY CS3040 and it works great. No problems, fast. I played WZ for an hour or two and left PS5 on for a couple hours idle and no overheating. It wakes from sleep mode with no problems.

But yeah, works good. Read speed was 5636.468 MB/s

Here is heatsink that I used: https://www.amazon.com/gp/aw/d/B086W5762H?psc=1&ref=ppx_pop_mob_b_asin_title
