You might be misremembering reality - yes, the original xbox shipped with a normal drive, but the X360 had a proprietary drive in a custom enclosure, but actually the most popular model didn't come with any drive at all - just a proprietary memory card. Then the Xbox One has a regular sata drive, but I wouldn't call it "user replaceable" - it's very hard to access and requires a complete disassembly of the console, while on PS3 and PS4 all you needed to do was remove one screw and the drive would come out. The same seems to be true on PS5 again.
