## AI overview

The article documents an attempt to add 25 Gbps Ethernet to a Mac Studio over Thunderbolt. It covers adapter cost, testing transfers to a NAS, throughput limits, and overheating in a passively cooled 25GbE enclosure.

## Source excerpt

I've been using the built-in 10 Gigabit Ethernet on my Mac Studio for a few years. It works fine: I can edit 4K video straight off my NAS over the network, and run backups at around 1 GB/sec. But... I want more. I upgraded my rack and my NAS to 25 GbE a couple years ago, and wanted to upgrade my main workstation, too.
