That's a myth about RAIDs and hard drives in general. I've built and
maintained many many RAIDs over the years (with several of them running
for years) and never have experienced a noticeable increase in drive
failures or drives failing closer together, etc. Nor have I ever had a
vendor even suggest such a procedure. Hard drives basically fail regularly
and randomly over the entire life of the RAID. Even when EMC installs
their big $500K frames, they don't add drives bit by bit or even from
different manufacturing runs.
