Aurender N100 internal hard drive or USB external drive?


I own one of the rare breeds of Aurender N100 variants that did NOT come from the factory with any internal hard drive storage, it is the same as the N100H in every other aspect.
Right now I have a 4tb WD HDD connected in the rear of it by USB which is fully accessible from the Conductor app.

I guess two questions really....

1/ Would I truly notice any difference in SQ if I went ahead and installed an internal hard drive vs my present usage of an external USB hard drive.

2/ If I went ahead and installed an internal hard drive, what model of hard drive is fully compatible with the N100, or does it really not matter? Or are there levels of HDD drives? Is SSD better than HDD? Are there levels of SSD?

Guess thats more than two questions but you get my quandary.
Seriously this stuff keeps me awake at night.........

That is strange.  I replaced the 1TB HDD in my Sony HAPZ1ES with a 2TB SSD and heard no difference in sound quality.  

Hi rcb3n474! I'm not a computer master but good enought to disamble a computer and putting back together knowing what am I doing! My problem is I'm not very familiar with linux. You said it was very difficult to make it work! Can you explain what was your way to make it? Did you clone the hdds? And what kind of partitions did you used? I intend to buy a second hand n100h but 2terra it is not enough to me so I need to know how difficult is to change to a larger hdd! Thank you!

Buy the Samsung EVO 4TB SSD. Put it into the tray at the rear and using the Aurender app format it. Then plug in your HDD with your stored music and copy it to the SSD using the Aurender app. Easy. 10%+ improvement in SQ.

Does the folder structure on the donor hard drive have to be a specific one before copying onto the internal drive?

Aurender is very vague on this in their user manuals.
