This is a pattern, the PS3 and PS4 both had end-user accessible bays which contain a 2.5" HDD. Any drive can be formatted even from blank using the console's safe mode.

> the XboX overpriced and proprietary SSD cartridges

This is also a pattern. The original Xbox and Xbox One had internal hard drives that were not end-user serviceable. The Xbox 360 used 2.5" HDDs in cases. The original 360 drives had a special port on the cases, for whatever reason. The 360 S/E drives used regular SATA connections, it's plainly obvious looking at one that the connector is just the edge of a 2.5" HDD.

Same with the PS2 as well, all you needed was the network adapter and you can pop in a standard 3.5” IDE hard drive. You can even get a 3rd party boot disc to copy/load games off the hard drive to improve load times.
