You can build a working 10-gigabit home network for around $200 by combining a budget 5-port 10GbE switch with Cat6a cabling and affordable PCIe NICs. The result saturates NVMe-backed NAS transfers at roughly 1,100 MB/s - about ten times faster than gigabit Ethernet - without enterprise-grade hardware or specialized wiring. Most of the savings come from buying NICs secondhand and sticking with unmanaged switches.
When Gigabit Becomes the Bottleneck
Gigabit Ethernet tops out at around 112 MB/s of real throughput. A basic NVMe SSD reads at 3,500 MB/s or more. That means your network is roughly 30 times slower than your storage - and for anyone running a NAS, this gap shows up fast.
