Best with RAID controllers or RAID-Z software

[Constantin]

The hardware RAID systems I’ve dealt with do everything - silently distribute data across multiple disks, resilver, and so on. The trouble is, as a user I’ve also had zero insight into what the array was doing, how the array is doing, and so on.

No doubt, the more enterprise-oriented hardware RAID systems likely incorporate better notification / status updates / and so on. However, none of them come close to the ability of ZFS to monitor the data continuously, detect bit-rot, and alert users to hardware issues.

Add TrueNAS with its ability to send verified snapshots to other systems, and you have a very bandwidth-efficient backup solution that is secure, safe. ZFS is but part of TrueNAS, the folk at iXSystems add a lot of value to ZFS!!!

Hardware RAID may be fast, convenient, and very simple to use, but it doesn’t even come close to ZFS in terms of reliability / data corruption prevention

Thanks a lot Constantin. I agree with you, the reliability of ZFS is great, and HW Raid can fail... but what I meant is that a dedicated HW Raid controller is not the worse thing in terms of reliability, Onboard Raids fail quite often (it happened to me on a Gigabyte MB), software Raid arrays (Linux or Windows based) can cause many problems, often corruption. I used both ZFS (on Sun Solaris servers) and HW Raid on Dell servers, and I've never had a data loss in 15 years.

And the comment you quoted above was strictly in the context of using ZFS, so all should be fine ;)

I'm sorry "mea culpa", I misinterpreted the post

Then your comment really doesn't have anything to do with this forum, does it? Particularly to revive a long-dead thread to post it?

I'm sorry if you read my other posts you'll understand. And sorry for reviving an old post
