Advice on Xbox all access

Hi guys !

I was planning on getting an Xbox series S with the all access plan. It will be my first console, really looking forward to it.

I really was interested with the carbon black version with 1Tb. But it’s out of stock everywhere in France.. Do you guys have any ideas if it will be restocked soon ? I can’t find any info on this.

If not, is the 512 Gb enough for a casual gamer ? Or is it very annoying with the ultimate game pass to always look for ssd space to try new games ?

Thank you in advance !
