June 11, 20242 yr I'm running two Supermicro 8-Port SAS/SATA Card - (AOC-SASLP-MV8) for a 15 HDD bay Unraid server at the moment. I want to put a GPU in the PCIEx16 slot so I only have room for one of these cards. I've got 11 HDDs right now so I'm using 8 ports on the SAS card plus 3 SATA ports on the motherboard. I an probably continue like this for a few years, to be honest. I'm thinking about how best to go forward. I only really use about 2-3 drives at any given time. So my options are to look around for two 8 port SAS HBA thats PCIE x1 (if it exists) or a 16 port SAS HBA on PCIE x4 or x8. Gen 3 PCIE x1 seems to have a max throughput of 1GB/s which should? be fine for 2-3 drives at full R/W speeds. I doubt there would be a quality chipset or if this even exists. Any suggestions are welcome. I'm not sure that running through the 3 SATA ports on the motherboard + 8 ports on the current expansion card is a good config.

June 11, 20242 yr Author It is enough for now assuming the 3 onboard SATA ports + 8 through the expansion card are stable (so far they are) but I'm trying to plan for the future and/or have the most stable system running. I've got 2 more empty ports on the motherboard as well.
June 11, 20242 yr Don't see the point in buying one now if you don't plan to need for years, but you can get a 16 port x8 LSI HBA:
