WD_BLACK SN850X 4TB Gen 4 PCIe NVMe SSD - $374.99 at Amazon (46% off) (Cyber Monday deal)

No problem! You will have as much space as you'll ever need for the life of the PS5, I think. And I use the Sabrent as well, but with the SN850, I heard it's the hottest running SSD, so I would think the SN850X will be even hotter, so I just got a new SSD cover, the ElecGear, which according to NASCompares, outperforms the Sabrent heatsink cover in temperature tests.

8TB SSDs are fairly new to consumers. I think only one or two manufacturers even make some, and they are currently priced out of reach for the average consumer. I assume it will be this way for some time. I'm happy with 4TB + my 2TB SSD inside the enclosure.
