Expert Tips

•Over-provisioning extra 10% kan fordoble drive lifespan
•Test drives under production-like workload før deployment
•Stagger drive purchases for firmware diversity (failure isolation)
•Always buy 10-20% spare capacity for hot-spares
•Monitor 99.9% latency, ikke kun average - tail latency kritisk
•Firmware updates i staging først, derefter rolling production
•Document baseline performance for troubleshooting reference
•Use vendor management tools - bedre end generic SMART
•Power loss protection er non-negotiable for databases
•Plan replacement ved 80% wear level, ikke 100%
