Ultra High Speed Data Acquisition mathod need advice!!

[seokgi]

Hello?
I have a question.
I am trying to make a device that generates 16-bit analog data about 120,000 times per second, and the data is generated for about 2.5 seconds.
I want to transfer the data generated here to a PC using MicroSD memory or serial communication. To store the data, I think I need an MCU (Only PIC Family) with fast internal RAM. If not, I think I will have to attach RAM externally. What MCU can store high-speed data?

If I have to attach RAM externally, what model of RAM and how should I attach it?

Does FC10 support this?

I would like to hear your advice.

Thank you.
