  ~$50/hr to transfer media at approximately one hour labor per 9-track tape
  ~$128/mo for a 10 x 10 warehouse space with climate control

Example:
    100,000 tapes stored in a 10 x 10 climate controlled warehouse

Cost to transfer media, not including cost of new media:
    = 100,000 * $50/hr * 1 hr/tape = $5,000,000

Cost to store 9 track tapes for a decade:
    = $128/month * 12 months/yr * 10 yr =   $15,360

These figures are based on advertised cost of a 10 x 10 public storage
locker at www.publicstorage.com.  I expect that GSA could cut a
significantly better deal on warehouse storage space for NASA than an
individual.

'nuff said.
