@quad@akko.quad.moe My (limited) understanding is the difference between SAS and SATA is mostly just protocol/signalling. I wouldn't be surprised if that exact backplane is also used on another product with SAS support. The backplane on my server (Silverstone CS380) supports both interchangeably, and for each bay the backplane has 2 ports labelled SATA and SAS, but only the SATA port needs to be connected, even for SAS usage, since that's the primary channel. The SAS port is the secondary channel for SAS 12G.
