Fiber on fs.com is SUPER cheap, cheaper than CAT6 and OP
https://www.fs.com/products/40228.html 15m (~49' 3") for $5.90 (OS2 1350nm for single mode)
No free shipping but if you order all your transceivers and cable shipping is only $7 and pretty cheap overall. Single mode (OS2 1350nm) transceivers are about $20. You can go multimode (OM3 850nm) for slightly cheaper, ~$13-15, still good to 300 meters at 10G, fiber is pretty much the same cost, which is stupid cheap and makes most copper xBaseT look like Monster Cable nonsense.
I have the 4+1 switch, three multimode and one single mode running a NAS, two PCs, and an old Proliant server. All runs great, hit up to 700MB/s off my NAS cache drive to my main PC's NVMe drive. Even non-cached read is 160-170MB/s--the native speed of my underlying RAID/HDDs, or about 80% faster than I'd get over my old copper 1gbps network. 1gbps is choking 5400rpm HDDs.
I'm going to upgrade to the 16 port once I buy my new rack...
> RPI4 has usb3 and full gigabit network, so for NAS purposes, it's completly fine.
2x USB 3.0 ports means you're quite limited in expansion. Even this cheap motherboard supports 4x SATA connections.
The Rasp. Pi4 itself can only reach 300MB/s read/write speeds. Modern hard drives are around 200MB/s, which means you're CPU-limited (or perhaps internal bus-limited) on mirrored-drive setups. (200MB/s across 2x drives == woooops, Rasp. Pi too slow for that)
10Gbps Fiber switches are only $240 now. You can remove the network bandwidth by using DAC SFP+ ports and an Ebay'd Mellanox Connectx-3 (under $50).
---------
Actual SATA drives give you more flexibility as well as better specs. Consider this 8TB USB Drive. Do you know if its SMR or PMR? I bet you its shitty SMR and simply undocumented on the materials. SATA-drives are just better documented and labeled than USB-drives in my experience.
Why avoid SMR? Well... because it sometimes hits 10MB/s transfer speeds., that's sequential mind you. 10MB/s is slower than many people's internet connection, let alone Rasp. Pi. So if you want any degree of reasonable responsiveness, you should stick with PMR or CMR drives only.
---------
A common NAS setup would be 3x hard drives (RAID5 like, or RAIDZ, with one parity drive). You simply don't have enough USB connections for that however.
I'm with u/Ghan_04 once I expand my homelab with more servers I plan to pick up one of the two below. Mine will be for a dedicated storage network. Nothing else in the house needs 10gig.

My vote for SFP+ is something like this https://www.amazon.com/MikroTik-Desktop-Gigabit-Ethernet-CRS309-1G-8S/dp/B07NFXN4SS
Here are my 2c's worth:
10/100 to 1Gb is already a 10x increase and you can do it on a shoestring budget, your server will probably already have Gb ports (any server built in the last 12-15 will have). So just swap out your current switch, for something like this and away you go:
https://www.ebay.com/itm/TP-LINK-24-Port-Gigabit-Rack-Mount-Network-Switch-10-100-1000-Mbps-TL-SG1024/312244627212?epid=99179800&hash=item48b33ae70c:g:GoEAAOSwtBZbo6ZR
It'll be more power efficient and probably less noisey.
10/100 to 10Gb I cannot really advise here, as this is something I'm only just doing, my 10Gb cards arrived yesterday, my DAC cables should be here today. But talking to other people on Reddit, conssus was the best /cheap switch for this are the Mikrotik ones
