It's the same drive, but AFAIK these drives actually contain 4x 1GB SSD's. The PCIe slot is more than capable of handling the data for the libraries and for audio. I ran a BlackMagic read/write test and on the 3GB I reach speeds of more than 5GB read/write and on the 1GB audio more than 2.5GB read/write.

What exact OWC 4TB card? This one:
https://eshop.macsales.com/item/OWC/SSDACL4M204T?
The issue with that card is it's stuffing four PCIe 3 x 4 lane M.2 cards into 8 total PCIe 3 lanes. So half the raw PCIe bandwidth on paper, although you'll see a lot less than that decrease for typical use. And all this is so much faster than what most folks are used to it may not be worth worrying about.
OTOH if you really want to build the fastest possible SSD storage with four M.2 drives you need a x16 lane card. Like this one
https://www.sonnettech.com/product/m...pcie-card.html. And my personal bias would be to go with Samsung M.2 SSDs. Including if you really want to squeeze most write performance and wear life then the the 970 Pro, but for most folks the 970 Evo is fine (and cheaper per GB and available in larger sizes).
These computers are great... but the new crop of PCIe 4 M.2 cards are arriving and they are fast, I've been lucky enough to play with them on some AMD servers. And the PCIe 6 standard is being worked on for 2021... isn't the technology treadmill wonderful
