Does anyone have any technical information on the SU-EM5804 cards available from AliExpress, eBay and Amazon and many others.
I am interested in what chipset they use, how much heat they generate, how noisy the fan is and whether the card would be suitable to host four ASM1166 nvme to 6 port SATA cards.
Based on the description this uses a bridge that allows one Gen3 x8 to four Gen3 x4. When combined with the ASM1166 it ought to give up to 24 SATA ports that should be fast enough for (today’s) mechanical 3.5" HDDs.
Any experiences with these? The pricing varies wildly from from ~$30 to over $400, for what looks like exactly the same product.
P.S.: I’d want to use this with Linux.
