Would SSD improve Index Only Scan performance by a lot?

As my table has gotten bigger, it takes longer to get a single row back
when querying a row by its btree index.

Right now the database is running on a traditional HDD. SSDs have a much
faster seek time than traditional HDDs.

Would switching to an SSD improve "Index Only Scan" time greatly? by at
least 3-4 times?
