An SSD is more than its fastest advertised read speed. The exact capacity, interface, physical format and endurance all belong in a useful comparison.
Compare the exact variant
A 1TB drive and a 4TB version of the same family can differ in cache, endurance and rated performance. A version with a heatsink is also a distinct variant.
Separate ratings from measurements
Sequential read and write figures in a datasheet are manufacturer maxima under stated conditions. They do not tell you the speed of every application or every PC.
Understand the warranty limit
A limited warranty can be bounded by both time and written data. Read the manufacturer terms alongside the TBW figure.
