I am trying to find a solution to create a 4MBit NVRAM module (FRAM or SRAM, doesn't matter) with a standard PC with Windows.
I want to store up to 1MB of data in less than 1 second with 50-100 write commands.
Unfortunately, the USB has a high latency and so I need up to 3-4ms for each write access.
So my question is: is there a faster way to send the data to a NVRAM module than USB? I was thinking with a PCIe interface, but probably I need some signed drivers to do it over PCIe. I can't find any modules with NVRAM on the web.
