Konfl1kt Posted July 17, 2022 Share #1 Posted July 17, 2022 Hi, I want to buy a RAID Controller for my NAS (MB AORUS Z370M-ITX/AC). I want to build RAID 6 and my MB doesn't support it. What should I know about RAID Controllers and XPenology? Which one will work? Thanks a lot! Quote Link to comment Share on other sites More sharing options...
Konfl1kt Posted July 17, 2022 Author Share #2 Posted July 17, 2022 I am considering ADAPTEC ASR-7805. What do you think about this one? Quote Link to comment Share on other sites More sharing options...
Konfl1kt Posted July 17, 2022 Author Share #3 Posted July 17, 2022 Can I have RAID 6 on my MB (software RAID) if my MB doesn't support RAID6? Quote Link to comment Share on other sites More sharing options...
flyride Posted July 17, 2022 Share #4 Posted July 17, 2022 The point of DSM is to provide RAID via software. It adds many features that "hardware" RAID cannot provide, such as self-healing with integration with btrfs, and RAID modes that are not possible with hardware, such as RAIDF1. So you should be looking for AHCI-compliant controllers to connect your disks. Some HBAs can do this (aka "IT" mode). Simple SATA controllers can do it as well.

(I mean drivers, as I understand not every controller will work because of that) Will ASR-7805 work? Also, still not clear for me (I am sorry for my ignorance) can my MB handle software RAID 6 if integrated controller doesn't support it? My MB has 6 SATA ports.

flyride Posted July 18, 2022 Share #6 Posted July 18, 2022 It isn't a matter of software RAID working with the motherboard. The OS is providing the RAID. You don't want the controllers, or the BIOS to be doing it. A motherboard with 6 AHCI compliant ports is a good base for DSM. If you add additional ports with an AHCI-compliant controller, no drivers are required. The ASR-7805 will likely require drivers as it is a host bus adapter. HBAs are usually quite a bit more expensive than plain AHCI SATA controllers. Look for @IG-88's threads on good AHCI controller options for something to start with, unless you really need 24 ports or whatever you will get from an HBA. 1 Quote Link to comment Share on other sites More sharing options...
Konfl1kt Posted July 18, 2022 Author Share #7 Posted July 18, 2022 Thanks a lot. If my motherboard can handle it by itself, I am more than happy. Quote Link to comment Share on other sites More sharing options...
