    Hey People

    I'm currently looking at setting up a raid. I am pretty new to raiding so I was wondering for reliability is it better to go with onboard raid or using a dedi raid card?

    Thanks

    Neither. Unless you're in a corporation or CPU bound, then you're better off using software raid

    What purpose are you looking at? Is this for dedicated storage (NAS, etc), or just for a bit of extra workstation reliability?

    Data integrity more then anything. It's for when I back stuff up. Speed isn't really an issue but fast the better I guess

    No hardware raid card will do block-level checksums to ensure data integrity, use software raid and scrub regularly.

    Where are you backing up from/to?


    An example of Software RAID - my "NAS" is an unRAID box with N-2 redundancy formatted to BTRFS (for checksumming only), which backs up to my games PC using Windows dynamic drives (mirrored / RAID1).

    Regardless of whether I used hardware RAID cards or even a different method of software RAID, the redundancy is for convenience only such that I don't have to resync a heap of data in the event of a drive failure at either end. Data integrity is covered via the NAS file-system, and the method of copying/verifying data between machines.

    Well currently I'm looking at weather it's viable because I got given a HP ML110 G6 with a P212 raid array card and was wondering if it really worth keeping it or pulling it out and putting it in the dustbin. If they arn't useful I will probably just turf it unless there are another use for them.

    If you have another HBA or enough SATA ports for your drives then i would turf it and use software raid. On the other hand if the ML110 is going to be used as a backup server and you would have to buy another HBA to replace it, then I would use it with the server.

    It's an old card but with a BBU you can get good performance out of mechanical drives, way better than anything software/onboard RAID can achieve.

    It will hold SSDs back though.
