We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Populating HBA or MB SATA? (alien.top)

I was wondering what your approach is to using available SATA ports for your array.

I have six MB SATA ports and eight SATA available via HBA (9211-8i)

Do you recommend populating all available motherboard SATA ports first, then using an HBA for the rest of the array? Is it better to have all of the data disks if possible on the HBA first as a priority?

Do you guys recommend keeping many disks as possible on the same controller? (i.e. populating HBA first)

I use motherboard ports first and don’t install a HBA unless needed, because it consumes a lot of power and prevents cpu idle

Yep; unless you need SAS support I would recommend onboard SATA first.

OP, I have the same HBA card as you, it gets toasty even just idling, and even hotter once you throw a load onto it. I measured ~10W power use just idling (no drives attached to HBA). I almost guarantee using onboard SATA will be more power efficient.

Even better, is if you can physically remove the HBA card until you need it.
