Seagate Exos 2x14 + G-Raid

I have a Thunderbolt 3 G-Raid with two 4TB Ultrastars. I ordered two 14TB Seagate Expansions from Costco on Black Friday to shuck and upgrade the G-Raid.

I was expecting Ironwolf Pro or Exos x14 but am seeing some of the recently shucked drives are actually Exos 2x14.

Does anyone have experience using 2x SATA drives in a G-Raid enclosure?

I’ve read SAS drives will appear as half or separate drives but couldn’t find much about SATA.

Am I the Guinea pig? Should I back out before I start?
