Which manufacturer of server HDDs is suitable for RAID 1?

Question

Hard disks

There was a need to create software RAID 1 for the server. Which server HDD manufacturer is the most popular in terms of fault tolerance and efficiency?
And another question - which is better, software or hardware RAID?

Answer 1

Any.
Better hardware if performance is important. Software is better if reliability is important.

Answer 2

I would prefer HGST (Hitachi) or their OEM drives for big vendors.
In general, all server disks ("high-speed") are more reliable and durable than "retail" ones. However, when they fail, they most often die tightly with large-scale cuts.
So do not forget about backups, because. the probability of recovering data from dead disks will be low.
