|External Storage||USB 3.2 HDD Support||USB 3.2 HDD Support||USB 3.2 HDD Support|
|Optical Drive||4K UHD Blu-ray Drive||4K UHD Blu-ray Drive||4K UHD Blu-ray Drive|
|Performance Target||4K at 60fps - up to 120fps||4K at 30fps - up to 60fps||1080p at 30fps up to 60fps|
- the die size is much smaller than expected, which means the console might be less horrifically expensive than presumed.
- the SSD has a huge IO throughput, meaning that less data will need to be stored in RAM
- the SSD looks like a memory card, which makes it easily swappable, but probably also very expensive.
- You can place the Series X horizontally, makeing it look even less visually appealing.
