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. Richard Sims
