If you don’t like bog standard Debian, you might really like Debian Testing.
It allows you to get decently new packages; I’d say typical lag is one week to a couple months depending on the popularity and/or complexity of the project.
I’ve been using it on my desktop for over three years just fine. It’s been quite stable while still getting new software versions in a mostly timely fashion.
Do note though that Testing means Testing; it’s not really concerned with being a rolling release distro, but with preparing for the next release, so there’s a few quirks:
- Sometimes, a package you’re using gets removed while its dependencies undergo a transition, forcing you to use the Flatpak.
- When a new stable release starts to get close (usually 6 months), they’ll start what’s called freezes, where they let in progressively less changes until release, after which things start speeding up again.
- As a general annoyance of anything rolling release-esque, software behavior may change over time, meaning a previously good config can suddenly break, and you have to fix it.
Personally, I’ve grown tired of Debian Testing and rolling release in general; while I still using Testing on my desktop, I’ve thrown Debian Stable on most things I’ve owned since then, and if I really need a newer version of software, I’ll just install the Flatpak or use a container.

Also, I feel like I’ve had good luck with k3b, though mainly for CDs.
As for drives, as others have said, USB ones tend to be janky; go for an internal. I like my LG WH16NS40 Blu-Ray drive.
If it’s a desktop, it should be easy to hook up with SATA, though if you have a newer case, you might need to dangle a cable out the side like I do.
If you have a laptop, though, you’ll probably need a USB adapter, though there might be a hack using an M.2 slot to hook up an SATA PCI-E card.
