I have a question. I read on this page of yours - https://nascompares.com/2019/10/07/thunderbolt-3-vs-40gbe-nas-in-2019 - that the DS3617xs can support 40GBE. Do you supply those cards? I can't seem to find much information for 40GBE, only 10GBE. Thanks in advance! I have tested this card on Qnap h
