Need to under stand Asynchronous USB


So I just got a Marantz ND 8006 Network CD player. Im using it as a network player and CD transport  and I output digital to my NAD M51 DAC. I’m using my IPad to stream TIDAL and that works tip top. However, it’s the USB inputs that concern me. I have a choice of a front connection and a rear USB DAC connection. 

Couple questions:

1. The USB DAC input is for a Mac or PC hook up, but is there any other way to use an input like this?  Does it have to come from a computer or can a USB hard drive work with an input like this?
2. More importantly the front USB input is NOT asynchronous.  I think they make a reclocker I can put in between the USB and the unit. My question is do they make a USB hard drive with a built in reclocker with a good amount of hard drive space?

this is all new to me, so any help would be appreciated.

1) You can use a USB flash drive, iPod or other portable player.
2) Asynchronus is what you want. The DAC being fed by the input reclocks the data and this is the ideal.
