  • An HBA (host bus adapter) is a SAS controller (or rather, has a SAS controller chip on it). You mostly just want to make sure that your host (the server) has enough physical PCIe lanes to use the whole card, otherwise you’ll get bottlenecked there. You also want to check whether you’ve got 6G SAS or 12G SAS capability. If your drives only support 6 gig, for example, there’s zero point in buying a 12G SAS card, which is actually nice because 6G cards are a lot cheaper. You do want to make sure you actually need an HBA and not a RAID controller though - they’re easily confused. Not sure if I actually answered anything there but I write SAS firmware and use HBAs all the time, so feel free to ask me more and I’ll try to piece together a coherent answer.









  • My friend frequents goodwill and one time, he came home super excited to show me the Husky mini socket set he bought. He excitedly told me “oh it was only $35!”, assuming he had gotten a great deal… that same socket set was also $35 brand new at Home Depot. It’s almost predatory because people just assume goodwill has better prices. That said… my friend should’ve been smart enough to double check that before buying it, lol
