I've read here that I can't mix SAS and SATA2 drives on the same controller – is that really true? I understand I shouldn't mix on the same channel, but the same card!?
For example, when I plug my 6-drive backplane (IBM x3650-7979) via SFF-8087 cable connector into an Adaptec 2405. Spinning 2 SAS drives (Ch.1), and 4 SATA2 drives (Ch.2+3) – Would it work?
Best Answer
Yes. This works fine and is not an uncommon arrangement. You may want to look into using nearline or midline SAS drives instead of SATA for future installations, though. These days, there are fewer reasons to use SATA disks given the high-capacity SAS options available.
