I need some help for a cheap lowpower NAS i am about to build.
Since my chosen mainboard doesn’t have enough SATA ports, i was looking for ways to add more.
The common advise I‘ve come across, is to use an HBA card like LSI SAS 9200-8e or similiar instead of cheaper SATA expansion cards like this
But when I was researching mainboards I also came across recommendations for boards like this which provides 6 sata ports.
The mainboard and the sata card use similiar chips (ASM1166 and ASM1064) to provide the additional ports. Is there any difference there? Why is the mainboard often recommended but the card is not? Does it really make a difference if the chip is on the board vs on an expansion card?
Edit: thank you all for the replies, very helpful!


I don’t have hands on experience with this, but I can say that once you move into addon cards the chance for hotswap from drive bays goes up. Hotplug is a feature that many of the on board and lesser data chips don’t support well.
