Hello,
This card I have and tried it on Turris 1.0 and it’s working. You dont need to install anything.
I created manual:
Připojení miniPCIe SATA karty - IOCREST Marvell 9215 [Turris wiki] (but I also said there that you need to figure out how to power HDDs, because I didn’t look at it yet.)
There is way how to power HDD (not sure about multiple HDD) from Turris - can be found here on forum, but I think it is very dangerous.
Anyway I think that you need to figure it how you will power it.
On old forum there’s a link for MOLEX power supply, but it has only 2A. So one maybe two HDDs will handle. So you need to buy two adapters or adapter, which has atleast 5A for 4 HDD.
And I asked Emko yesterday about Turris rack resurrection I’m waiting for their reply.
