Very slow Android USB file transfer

I’ve been used to my old phones that always had MicroSD card slot. So I’d remove the cards & put them in a card reader and transfer the data off to a PC/NAS. would get 30MB/s transfers. Now I got this new Pixel phone with Internal SD only… & it’s a dog trying to transfer any data off… especially in the Android/Data folder. Takes hours & hours… & fails a lot. Any pointers/tips ? Thanks.
