I'm under the impression that SD memory is a non-volatile memory
& so is SSD.
However are SD memory's throughput / performance comparable
to that of SSD since SD card's IO did not involve any mechanical
movements / spinning ?
Or is SD's throughput limited by the built of the SD slot in our laptops
just like USB 1.1 & USB 2.0 & USB 3.0 are limited due to the design
of the USB ports ?
