Enough is an understatement. 2TB is HUGE. The core DAZ Studio application is just around 1GB installed. That leaves you a ton of storage for your assets. Heck, I only have 90GBs of DAZ products installed and 212 GBs of HDRIs from Polyhaven on my PC right now.
Are you planning on hosting your files for download? Seriously, there's no need to install everything since it will just slow down DAZ Studio (eg. morphs are a pain). I have 8,000 zipped backups taking up 700GB of space in my NAS, though.
