February 16, 20251 yr I am trying to build a new NAS and migrate my current Unraid setup to a new rig. I have some free 14Tb drives from work, but they are SAS drives. I've been doing research online and it seems many posts tell people to just go with SATA. I feel like six 14Tb SAS drives aren't cheap, so I would like to build off these drives. Can someone let me know what type of HBA card is suggested and also what cable I would need? I saw some SFF-8643 to SFF-8482 cables but I'm not sure if the SAS drives can be powered from those.
February 17, 20251 yr Author Thanks, I will get a LSI HBA as suggested but I am still a little confused as to how these drives get power. Looking at the cables provided, it doesn't look like they will fit my drives. I will not be using a backplane. Please see picture of my drive.
February 17, 20251 yr You can then plug your standard SATA power connector on the cable shown by Jorge. It seems obvious, but we had a long debug session some time ago with a user that didn't plug the power connectors.
February 17, 20251 yr Author They probably thought the HBA card was powering the drives. Sounds easy enough, thank you. Is this cable called "Mini 4 SAS 36-Pin SFF-8087 To 4 SAS 29-Pin SFF-8482 Cable Connectors with 15 Pin SATA Power"?

February 20, 20251 yr Author I bought my HBA and cable but now I realized my SAS drives are host-managed. Is there any way to make host-managed SMR SAS drives to work with Unraid?
