Jeez you're buring through so much of the drive's lifespan just checking the damn thing. If a failed drive will cause problems worthy of this amount of burn-in time you need a more robust setup.

I run all used ebay drives. Except for a glance at the smart data before addng them to the array I don't test them at all. Just keep an extra drive or two on hand as spares. Life's easier when you plan for failure instead of fighting it.
