Dell R640 GB/s Maximum Speed

Question

I have a Dell R640 with a 10x2.5' form factor.  I am trying to find out what is the fastest SSDs I can install are for SAS, SATA, and NVMe.   For instance, my old Dell R620 only accepted SATA 6 Gbps and SAS 12 Gbps SSDs.  What are the highest speeds in Gbps I could achieve in an R640 for SAS, SATA, and NVMe SSDs?   Thank you
