How many solid-state disk read speed is appropriate, how many solid-state disk read speed can be achieved

What is the appropriate reading speed of SSD hard disk?
The continuous reading of SSD hard disk is generally around 500MB/s, and the continuous reading speed is generally around 500MB/s. For the same SSD, the larger the capacity, the faster it will be.

For example: two SSDs of the same brand with the same main control, one is 128G and the other is 256G. Both SSDs use hard disk chips with a single-chip capacity of 16G, so a 128G SSD requires 128/16=8 front-end chips, and a 256G SSD requires 256/16=16 front-end chips. Coincidentally, the read and write speed of SSD is very fast. When it is reading and writing, it is equivalent to reading and writing multiple read and write chips at the same time. Obviously, the 256G product with 16 bezel chips can read and write at the same time compared to the bezel chip, so the speed is faster than the 128G product with only 8 bezel chips
How much can the read speed of SSD hard disk reach?
At present, the reading speed of SSD hard disks is generally 500MB/S, and the fastest is 1000-1500MB/S. Of course, there are SSD hard disks with a maximum reading speed of 7000MB/s, but the price is relatively high.
