I’m somewhere in the vicinity of 600GB. Most are FLAC and ALAC but I have quite a few that were imported before I realized that there was an ALAC option for importing.
In terms of physical media, 17" by 18.5" by 43" for 13,525.5 cubic inches or 7.83 cubic feet or 0.221 cubic meters. I haven’t bought physical discs for years, and have maybe 700 still around.
LOL, I have about 15-20 linear feet of vinyl, still. I do have about 30 shellac 78s and Edison Diamond Disks. And a pretty good Edisonola stored in the attic. Works well, but needs a grille. Has extra tone arm extensions, both the diamond and two Victrola adapters that use the steel needles. I was lying about wax tubes.
Well, I just started a Roon trial a couple of days ago, so I just happen to have handy statistics on the main e-collection:
2,708 albums (2,491 unique, per my count)
1,292 artists
40,639 tracks
1.38 TB
95% FLACs and I’m replacing the MP3s when I can
Before COVID interfered, I had a monthly budget of $20 to spend on visitations to Goodwill stores etc looking for more music to acquire. Use-it-or-lose-it to force me to do it regularly. I think I should go out tomorrow, and re-start that habit.
I’m in a similar area. My classical flac library is about 0.5tb and my non-classical is about 4.5tb. Mostly CD rips, but with a few hi-res downloads too.
Roughly 400 CDs, 1000 records, 50ish music DVDs, & at last count about 8000 digital files most of which pre-date streaming services by a decade or more (honestly I mostly stopped bothering to rip, buy, or download digital files with the advent of lossless streaming)
