Be careful, most cheap NVMe drives have low endurance. Llike, not "Oh, you're just hand wringing about nothing," endurance ratings but an actually and relevantly low number of terabytes that can be written before the drive becomes failure-prone. They also usually lack a DRAM cache, so certain operations can be as slow as a mechanical hard drive, thereby negating the major advantage of opting for solid-state storage.
If you're running a database server or something with lots of writing and data you don't want to lose, I can see the concern.
But a drive for gaming is the best possible use case for a lower endurance drive. Even a poor drive can write the whole thing 200 times. I doubt many people would even get close to that.
I completely agree, Microsoft shouldn’t have been greedy and used proprietary storage. Sony did it the right way by allowing you to add your own which lets you find a good deal.
Which is ironic since Sony spent two decades trying to make Memory Sticks, UMDs, and MiniDiscs happen. I think they've finally learned their lesson on proprietary storage.
PS5 will also support up to 8TB of additional storage. Series X maxes out at 2TB.
