OCuLink to SAS cables - Needing help understanding them

[Analogue Blacksheep]

Currently looking at some OCuLink (SFF-8611) -host- to SAS (SFF-8643) -device- cables to potentially use in an adapter. The adapter will be housing a Samsung 970 Pro which has a max sequential read speed of 3,500 MB/s and a max sequential write speed of 2,700 MB/s. More info on the drive here...

I plan on using it as a scratch disk which means I need high speeds and good endurance.

However trying to find a cable for this has proven to be rather confusing...

This cable has a maximum data transfer rate of 8GBPS,
This Delock cable has 32GBS per second speed,
while on this Supermicro one doesn't mention data speeds, but rather says OCuLink x4.

I'm not sure would work here?

What cable would be the best to work with the 970 Pro with no speed loss?

3500 megaBYTE per seconds is 28 gigaBITs per second. 32 gigaBITs per second is the speed of FOUR PCI Express links. I wouldn't that ebay thing although eight gigaBYTEs is exactly 32 gigaBITs per second so it could work but hey it's from China so even if theoretically works, do you really want a cable like that made from the finest chinesium?

I forgot about the difference between gigabytes and gigabits. I've ordered the Supermicro cable.
