Just joined the club with a DXP2800 - a few observations and questions

Hi folks,

After collecting tons of external HDDs/SSDs I decided to bite the bullet and get a NAS. The DXP2800 was a natural choice and I've added two 12TB Seagate IronWolf drives and scavenged a 2TB NVME.

My home network is four Nest Wifi Pro routers on 1Gb wired backhaul and a central 1Gb switch. Clients are M3/M4 Macbook Pro's and M4 Mac Mini and two Wiim Ultras.

I'm quite impressed with the interface and setup. A few observations:

1. I was surprised that my MacOS APFS drives when plugged in to the NAS wouldn't properly read/write, although it would show the files. I'm transferring all of these via the network now.

2. My NVME drive has the chips on the wrong side for the thermal tape, hopefully that's OK.

3. I've been a bit disappointed by the Wifi transfer speeds, it's tediously slow to upload at around 10-20MB/s. Sadly my house and ADU aren't wired up for ethernet beside in a few places, so I've had to place a laptop by the NAS/switch to get some of the initial transfer from external drives done.

Which leads me to some questions...

1. What would you recommend to improve my connectivity? I could switch to an Eero 7 Pro/Max system but I'm not sure the current Macbooks would take full advantage given they don't support Wifi 7. Is anyone out there getting good speeds over wifi? I guess it's fine for slower transfer speeds but video editing or mass file transfer seems a no go.

2. How should I best utilize my 2TB NVME? Should I use it all as cache?

3. When I install Jellyfin it asks me for a resource path and an extension path - not sure what I should put in for these..

4. Anyone use their NAS with a Wiim for streaming flac audio?

Thanks!!
