https://eshop.macsales.com/preorder/OWC-Aura-SSD-for-Mac-Pro/ Seems the Aura is the only 2TB SSD option right now, but its for the new Mac Pro. (1) Is there some PCI card adapter that can use the new Mac Pro SSD memory stick format? (2) and, most importantly, would such a PCI adapter card be able to boot an old Mac Pro with the new mac pro SSD stick in it? I seem to remember some folks found one, but some quick searches didn't reveal it. (3) Has anyone tried this with an early aura card? Seems like it would make a decent upgrade.
