Abstract:
In evaluating the relative merits of storage vendors, one important consideration is system availability in the event of
a drive failure. And because of the potential for data loss, the time during which a drive is being rebuilt onto a hot spare
is critical. Demartek compared drive rebuild times for the (...)
