Any of them can produce= a bad drive. ++ All the consumer drive manufacturers are in a super-price-conscious market. For the most part their drives work as advertised, and basically all of them have made a model with an abysmal failure rate at some point. I think Backblaze still publishes their stats and I don't think any manufacturer stood out when it comes to these cheaper consumer drives. The enterprise stuff probably is more reliable, but for HDD I don't think it is worth it - just use RAID. I've personally been trying to shift towards solid state. Granted, it is about double the price of large 5400RPM drives, but the performance is incomparable. I've also been moving more towards used enterprise drives with PLP/etc and where I can find the drive endurance info on the ebay listing. You can typically pay about $50/TB for an enterprise SSD - either SATA or NVMe. You'll pay a bit more if you want a high capacity drive (U.2 16+TB or whatever). That's in part because I've been shifting to Ceph which is pretty IOPS-sensitive. However, it is nice that when I add/replace a drive the cluster rebuilds in an hour at most with kinda shocking network IO. I'll use cheap consumer SATA/M.2 SSDs for OS drives that are easily reimaged. I'll use higher performance M.2 for gaming rigs (mostly read-oriented), and back it up. Be aware that the consumer write benchmarks only work for short bursts and fall to a fraction of the advertisement for sustained writes - the enterprise write benchmarks reflect sustained writes and you can run at that speed until the drive dies. --=20 Rich
