I'm attempting to record WAV audio with a Teensy 4 with Audio Board D (SGL5000).

Can the writing speed of the SD port incorporated in the Audio Board be improved, if I solder a 23LC1024 RAM? I just ordered the chip so maybe a bit late to ask

I've read bad things about the SPI SD Card writing speed, which worries me because I need to record two channels simultaneously. But the size of the T4 bundle is really convenient for my application.
