ZimaBlade Thunderbolt PCIe cards

I have zimaBlade. I installed ZimaOS (1.3.2) to get better Raid and user management for NAS access. so far everything work great. I use portable SSD for work on the Go (Samsung T5, T7 and T9, Crucial T9 pro) is there a recommended Thunderbolt PCIe cards for zimablade?.
I would like to use it for:
1- connect external SSD for data transfer to the Sata drives connected to my ZimaBlade(2x16 TB HHD).
2- Direct connection to the computer (Thunderbolt PC Direct) in ZimaOS 1.3.2. which should be faster for my work flow.

The PCIe speed on ZimaBlade may not fully match the maximum speeds of high-end Thunderbolt cards.

If your main use case is to connect external SSDs (like your Samsung T5, T7, and T9) for data transfer to the SATA drives (2x16 TB HDDs), you can consider a PCIe to Type-C expansion card. While the actual speed may be limited to around 1500 MB/s, it’s a more budget-friendly option and will work well for your needs.
