What this match tells you
One point for each wish that is confirmed by the documented specification. Unknown is shown separately and never counts as a match. Extra capacity above your wish earns no bonus. Every wish counts equally. These are example wishes you can change.
A specification match, not a test score. The specification match does not measure sustained write speed, heat or reliability.
