Pretty much, but it depends a lot on the vendor and how much you spent on the drive. A lot of the assumptions about enterprise SSDs is that they’re powered pretty much all the time, but are left in a low power state when not in use. So, data can still be refreshed on a timer, as long as it happens within the power budget.

There are several layers of data integrity that are increasingly expensive to run. Once the drive tries to read something that requires recovery, it marks that block as requiring a refresh and rewrites it in the background.
