If everything went fine during production you’re probably right. But there have definitely been batches of hard disks with production flaws which caused all drives from that batch to fail in a similar way.
Comment on Can I use two different drives?
duncesplayed@lemmy.one 6 months agoTo the best of my knowledge, this “drives from the same batch fail at around the same time” folk wisdom has never been demonstrated in statistical studies. But, I mean, it’s certainly not going to do any harm.

I know it’s only what I’ve experienced but I’ve been on a 2 weeks of hell from emc drives failing at the same time because dell didn’t change up serials. Had 20 raid drives all start failing within a few days of each other and all were consecutive serials.

It may, performance-wise, but usually not enough to matter for a small self-hosting servers.

I wouldn’t mix 5400 rpm drives with 7200 rpm drives, but if the rpm & sizes are the same, there won’t be any measurable performance loss.
