If you really want to know I can explain, all you need to do is ask.
I'll start with simply saying that an SSD is, actully, very similar to the technology found in the old N64 or even older SNES or NES cartridges or SD cards. Unlike CD's/DVD'S or even hard drives which need to be spun and read like an old record player SSD access the information stored almost instantly. You probably remember that N64 games loaded WAY faster than PlayStation games did back in the day, that's why.
Solid State Drives are only limited by the bandwidth of the semiconductor connection, which is where NVMe comes in. A standard SATA connection is limited to about 6Gbps, a NVMe connection goes up to 32Gbps. So SATA SSD's are faster than hard drives and optical discs and NVMe SSDs are faster than SATA SSD's.
