Just for your information:
The Vita Memory Cards can only be written to so many times before they break (same with all flash storage). Using the Memory Card as game storage now may stop you from using the Memory Card when you need it - like if your vita needs to be reformatted or if you want to change storage location software.
Nobody is making memory cards anymore. The memory card is required for Vita 1000 Jailbreaking.
A 64 GB Vita Memory card costs over $100USD. 1TB MicroSD card costs just over $100USD. It's cheaper just to make ux0 larger.
