October 26, 20232 yr Hello. I'm looking to upgrade my nas, adding more disks. What should I use to get more SATA ports? A SAS card like this 03X3834 EXPANDER CARDS 16 PORT 6GBPS SAS SATA EXPANDER FOR HBA CARDS SAS2008 SAS2308 - AliExpress or a card like this TISHRIC PCIE SATA 4X 1X to 2/8/10 Ports SATA 3.0 PCI E Controller pci Express Multiplier Expansion Card 6Gbps Add On Card Riser - AliExpress ?
October 26, 20232 yr Hi @blue8lucian, you should start here : Note that Expanders are not controllers and are only working similarly as a network switch. You would need to connect it to a SAS controler. As for the SATA card, it's hard to judge without a link, but more than 4 SATA connectors on a single PCIe lane generally means one or several port multiplers and that is not recommended. More details in the thread above.
