Hi everyone, a colleague of mine told me that it might be not wise to use RAID5 with drives that exceed more or less 12tb. He said the stress-time put on all that are left while restoring a failed one becomes a risk that one shouldn’t take with these sizes. I’ve always used RAID5 for whatever I did when I wanted redundancy but in all honesty I never had a drive failing on me so in reality I never ‘used’ raid really.

I’m about to upgrade my 14TB Toshiba Enterprises and for space reasons I’d like to go for 24TB instead of buying more smaller drives. Also whenever I bought drives they too soon turned out too small so this time I want to really get some space for the space they take.

I would love to have a discussion about raid setups for these massive drives. If I remember right RAID5 was also created some time ago when drives used to be smaller. What’s your experience?
