Upgrade Storage

Moving from spinning disk to SSD or NVMe storage provides the largest single performance improvement — often 10-50x faster I/O. Consider NVMe for boot drives and high-IOPS workloads.

Upgrade Networking

Stepping up from 1GbE to 10GbE or 25GbE eliminates network bottlenecks for VM migration, iSCSI storage traffic, and backup windows. Most modern workloads benefit from at least 10GbE.
