We know : tkaiser is a regular in the chat and a mod in OMV - so hes got personal interest in the matter and insight. Useful and valuable posts - good thing you shared them on here.

Should I be saying "Is that you luke" as the SoC force is with that one.

Been reading TKaiser comments for a while and much appreciated.

and if he doesn't use the word 'crap' in one sentence with the name of your product, then you probably did something right

eMMC Interface
 Compatible with standard iNAND interface
 Compatible with eMMC specification 4.41, 4.51, 5.0 and 5.1
 Support block size from 1 to 65535Bytes
 Support three data bus width: 1-bit, 4-bit or 8-bit
 Support up to HS200; but not support CMD Queue and HS400

With a 200Mhz clock & 8 bit data bus the interface should be capable of a theoretical throughput of 200 MB/s

But what HS200 is and how its employed on the ROCK64 ??! I am not worthy

If we are getting the same speed as SD purely because of the cost of the sourced eMMC in the store then it doesn't make a lot of sense if for a few bucks more you can more than double SD throughput?

HS200 is basically the spec for running eMMC at 200Mhz (and therefore theoretical 200MB/s output, as you mentioned).

The eMMC that came with the preproduction Rock64s comes close to saturating its bus. It is the same chip family (Foresee NCEMBSF9) that comes in the Pinebooks. I think it is still what is for sale on the Pine store, though I could be wrong.
