Q: How hot will this get since this is basically a external ssd with no type of cooling fan?... I have the 2Tb and it does get a bit warm while gaming long sessions on my XBox X... which then I switch to PS5 Pro or my new Nintendo Switch2

A: This is an internal card, not external. There's a slot on the back which integrates this card as a secondary internal storage. The hardware casing acts as a heatspreader. No fan is necessary

Q: How many games can this new 4tb ssd storage expansion card hold for xbox series x?

A: That Honestly depends on the game, as the sizes can vary by a LOT. If you assume the average AAA title is 60 Gigabytes, then you can fit around 60+ games or so (minus around 400 gigs or so used for the swap file)

    Storage monster

    If you’re tired of deleting games to clear space this thing helps. At least until GTA 6 drops.
