IMO, ASRock.

Considering that they’re probably the only mobo manufacturer that officially supports using consumer AM4 CPUs on a server (see ASRock Rack), and always supported ECC ram on all AM4 motherboards - and that I haven’t had anything negative happen with any of their products so far (at work) - I personally would choose ASRock next.

Haven’t had the chance to try them for AM5 yet, sadly.

I have been using exfat since it has support for big ISOs and is compatible with Linux.

The ST400 does NOT support ext4, but I didn’t care much: I wanted a partition scheme that was accessible from both Windows and Linux.

I don’t recall ever having to change the firmware for that, nor for NTFS which I have used the very first time when testing it out.

For my use case, I am using a cheap 120G ssd on which I only keep ISOs, so I never found myself needing multiple partitions…

Edit: The documentation does say that it supports multiple partitions, but again, I never tested that out, so YMMV…

Hope this helps.

Take a look at the IODD ST400.

It’s a hardware solution to your problem: you put multiple isos on an ssd, plug your ssd into the ST400, then plug the ST400 into the computer you want to live boot from (through USB).

From the ST400 you can quickly swap the active ISO, and it acts like a virtual DVD drive to the target computer, and you’re basically ejecting and inserting a new DVD every time you do so.

You can also mount it for RW operations (ie. for inserting new ISOs without having to remove the SSD), for which it acts like a regular usb disk - but I recommend using it usually in RO mode to avoid data corruption.

It’s not that user friendly, but once you get used to it, it’s a perfect multiboot tool to have in your belt.

My reasoning for suggesting unlisted instead of private is because the recipients might not have a YouTube account, so making it unlisted means they’re certainly able to view the video.

Have you considered keeping them on YouTube but unlisted, so that they don’t show up on your profile nor in youtube searches?

Otherwise, you could create a Google Photos album, but either quality suffers, or the videos will take a lot of space.

All the other options I could suggest either call for a recurrent payment, but trust me, it gets tedious after a while (ie. VPS with Peertube or similar), or call for losing quality by a lot (ie. Whatsapp or Telegram channels/groups), or quickly become unpractical (ie. Mega, Dropbox…)

There are plenty of choices, and if you’re 100% sure you’re fine with recurring payments and having to constantly mantain a system/keep it updated and secure, then go ahead and make a VPS, but if you’d rather have it be convenient, look into additional YouTube settings or common alternatives like Vimeo.

Have you looked into Cloudflare Tunnel? It’s a turnkey solution that does exactly what you want. No idea what the cost is though.
