I need a card that can fit two WD Black SSDs with heat sinks. The Riitop card of similar spec has the mounts too close together for both SSDs to fit. What is the space between the two connectors?

Dear, thank you very much for your inquiry. As we are not currently in the warehouse, I will measure the dimensions of the two interfaces and reply to you directly tomorrow during the day. Is that okay with you

PA21 dual M.2 NVMe adapter converts two M.2 M-Key NVMe SSDs to PCIe 4.0 X8 interface. It supports all common M.2 SSD sizes from 2230 up to 22110. Designed without built-in bifurcation module, it needs a motherboard that supports PCIe bifurcation to recognize and run both SSDs normally. Compliant with PCIe 4.0 protocol, it maintains high-speed and stable data transmission. Compact structure and simple mounting make it a great choice for multi-NVMe storage expansion, DIY hardware upgrade and idle SSD reuse.
