I am building a NAS in RAID 1 (Mirror) mode. Should I buy 2 of the same drive from the same manufacturer? or does it not matter so much?

I've heard just in general. The resilvering process is hard on all the remaining drives for an extended period of time.

    So you're saying I should be running RAIDz2 instead of RAIDz1? You're probably right. 😂

    I made that switch a few years ago for that reason.

    That said, as the saying goes, RAID is not a backup, it should never be the thing that stands between you having and losing all your data. RAID is effectively just one really dependable hard drive, but it's still a single point of failure.
