They are currently stored on an eMMC card using an Orange Pi 5 Plus. I get the following speed in read and writes to the card. Would that speed it up that much using ram disk instead of the eMMC card.
/dev/mmcblk0p1:
Timing cached reads: 2398 MB in 2.00 seconds = 1200.31 MB/sec
Timing buffered disk reads: 716 MB in 3.01 seconds = 238.21 MB/sec
