Per recent PMs with (S)ATAman, he was testing with 840 and 860 prior to COVID-19 and hopes to return to that work after his recovery.
He seems to think that the EVO 860 might also be good for use AFTER a bit more R&D.
“I am using 1TB 840 EVO now, connected to 3114 in G4MDD.
The first goal - as usual - is to update the "X" driver. I do not see, why it wouldn't work in "9".
I want to finish that "X" driver ASAP, I had it working, it's something incorrect there again, looking at that.
The speeds of 3114 in G4 aren't great and it is not a surprise. The reads on a single channel top at 95 MB/Sec, the writes at 62 MB/Sec.
I have the SIM for 3114 and FCode, too - but can't work on everything the same time.
So I would say "yes", I expect it ultimately working.
The speeds of all derivates of SImage / CMD 680 PATA controller won't be great, but that's how the internal works of that controller are and besides, this is the controller with the quickest way to have a complete thing.
The PATA 680, 3112, 3512, 3114 chips are almost the same, the difference is the number of ports, the interface and hot-swap capabilities (PATA, SATA) and not much else. I noticed, some 3114 (SIIG) have Micrel regulator, they should "sleep" on the Quicksilver and D/A.”
Many thanks to (S)ATAman and well wishes from us all for his complete and speedy recovery!
(AND "hats off" to MacTron and to Torvan as well!)
