Max drive size for G-Speed esPro?

I have 2 older G-Speed esPros that are still working nicely but I’d like replace the drives with larger capacity drives if possible. Now they have 3TB drives. What the max drive size I can use? Is there any other concerns I should be aware of?

Thanks for your help!

They will technically support pretty much any larger drive, however the largest we made the es Pro units is the 32TB unit. 4x 8TB drives. 32TB eS Pro

Hi Rydia,
can you provide the sku for a Western Digital 8 TB compatible with the GTECH G-SPEED esPro.

I’m not Rydia and not a part of WD.
