Understood. The internal eUFS is a good choice. If I recall correctly, eUFS and UFS Card can share the same controller, thus lowering the cost and complexity. If the Switch revision is to adopt the eUFS, simultaneously replacing the microSD Card with UFS Card could actually be advantageous.The UFS storage I'm talking about would be the internal storage. Yes I fully expect microsd card slot on the device, they will likely use internal storage for any games that require high speed storage, microsd cards can be used for anything else.
Phison can produce UFS Cards (see below) but I don't know if they have any OEM clients. What's more, according to Thraktor any eUFS manufacturers can pivot to UFS Card easily. So if Nintendo wants to release Switch-branded UFS Cards, they should be able to contract a partner to produce them at a reasonable cost.There's also UFS Card 3.0. However, I believe Samsung's the only company currently designing and manufacturing UFS cards. So unless Nintendo decides to aggressively adopt UFS cards as an external storage option for DLSS model* exclusive games and contact other companies (e.g. Kioxia, etc.) to manufacture UFS cards, I don't expect UFS cards to really drop in price, at least as quickly as SD/microSD cards.
By the way, the Orin X made its first public appearance through Zhiji Motors (a.k.a. IM Motors): "NVIDIA Orin X chip adopts brand-new NVIDIA GPU and 12-core ARM CPU, made of 7nm process, single-chip computing capacity is up to 254 TOPS per second. It is at the top level among the current mass-produced automotive-grade AI chips. It is reported that the single-chip computing power of this chip is about 10 times that of Mobileye's latest EyeQ5 and 3.5 times that of Tesla's HW3.0."
