So the new Sonnet M.2 4×4 PCIe Card – 4 NVMe SSDs promises concurrent data transfers/read and write speeds up to 12,000 MB/sec – I’m having a moment of blindness: If the architecture of a new mac supports 6000 MB/sec transfer speeds, how is what Sonnet claiming possible? They also claim speeds up to 6,000 MB/sec on 2012 macs with 3ghz architecture. I have a gap in my understanding can some one fill this in – Thanks in advance.

I have the Sonnet M.2 4X4 Silent SSD PCIe Card with 2 x Samsung 970 EVO Plus 2TB in a 2019 Mac Pro.
Top speeds average around 5200 across the board.
Not sure how to his the advertised mark.

So here’s sonnets response to my question about speeds – :
OWC connects 8 lanes to the PCIe slot (24-lane PCIe bridge chip). Sonnet connects 16 lanes to the PCIe slot (32 lane PCIe 3 bridge chip). If you are using a RAID 0 of 4 SSDs, The Sonnet is nominally twice as fast.
And by twice as fast I said I’d achieved 5700 with the OWC M2 – is it remotely possible they’re confused?
