Personally I never reached a point where I had to use any kind of storage software. All you need is a good external storage and a little bit of organization.
If anyone is serious about data storage I would honestly choose external SSDs or an enclosure that supports SSDs. I’ve had terrible experiences with hard drives failing over the years or clicking and corrupting my data.
The Llama 3.1 models are probably the best all-rounders, with the Llama 3.1 8B version being the most popular.
