From what I've read, drives can reliably reduce speed only to about
50%, so speed-matching is a very limited thing. Collocation and
concerted reclamation of serial media need to be in effect to keep
restorals as efficient as possible. Reclamation is usually thought
of as a means of supplying the scratch pool, but its value as a
restoral performance aid needs to also be kept in mind.
