2.5 Gbps and 5 Gbps would actually be beneficial for me. My NAS can handle ~2 GB/s of writes (backups and whatnot) but instead, I have to wait *hours* for my desktop and my wife's desktop to back up due to the limitations of gigabit.

Speeds on a decent SAN system are insanely fast for sequential transfers. I have no idea how fast the system I work on really is (for single-user purposes) since it can max out a 40GB connection no problem (very roughly 4GB/sec max, if you're curious).
Of course that metric really doesn't make sense for most SAN arrays as they are looking at 100+ transfers going on at any given time, but I'd expect that a decent 8-drive NAS could put out ~800MB/sec == 10Gbit connection on average.

For sequential transfers, yes, but random IO (like loading games) is a lot more brutal to optimize. It's still not too bad if you set up your NAS properly with a decent amount of RAM and a good CPU/NIC, but it's definitely not much faster than a single HDD for loading games.

The main issue I'm running into is money - it's not trivial to buy 8 decent drives and I don't currently have a system with the SATA ports / Case / PSU that I can easily repurpose, so I'd need to get that too. Fortunately I have a spare Bulldozer CPU that should work well... not sure if I want to use it 24x7 though due to power.
Of course, once I do get the ~1000 together I'll need to avoid the urge to upgrade my aging Sandy Bridge-E PC...

Or you could transform that SandyBridge-E into a the corner stone of your NAS. That what I did. Even figured out how to host VM's a few years back on NAS4Free via VirtualBox.

If I've got a dumb 2.5GBit switch (assumption for this hypo) connected to the router by a 1GBit link, does not the speed of that link constrain the packet flow between ports on the switch? If packets have to hit the router to be routed through a dumb switch, why isn't the router the road block?
When y'all tell me I'm wrong, please do it in words I might understand.

EDIT: Just realized these are SFP+, which means you'd need a transceiver: https://www.amazon.com/dp/B016OYD0D4/
EDIT 2: Well hey look at this one! $250 for 2x10GbE. https://www.amazon.com/dp/B01LZMM7ZO/
