Loading Models from External Storage; How Fast is Fast Enough?

[CallMeAl1973]

I'm toying with the idea of purchasing an external SSD and attempting to run models from there. Curious how much of a performance hit I could expect to take? I'm currently running models from internal storage, an NVME SSD, and typically get around 1.5 tokens per second using 30B models.
My machine has a USB 3.2 Gen 2 Type-C port, but I doubt any budget SSDs will come anywhere close to taking full advantage of that. I was considering something like this:

I'm sure i'll take theoretical performance hit, but I'mcurious approximately how much of one, and would it be noticeable?
Thanks,

I do it and there is no impact at performance, just the initial load of the model to ram that is slower.

Awesome. Thanks! What sort of external drive are you using?

A common SanDisk USB 3.0 pendrive.
