Not strictly true. All SSDs have some degree of overprovisioning: physical
NAND capacity that is not exposed to the host, but is used for sparing and
other housekeeping. The difference between read-intensive and mixed-use SKUs
is often simply that a greater percentage is thus reserved.
So you can think of that 50GB as getting you longer endurance.
