RAID-10 Initialization - Technical Explaination?

[ice-d]

I am initializing my NAS RAID-10 with:

10 x 20 TB drives. In the foreground.

Can anyone point me to or explain exactly what gets done on on the disks?

 

My guess is that stuff is written to drive and zeroed out.

 

Due to this taking multiple days/week to finish, I was hoping to get a technical explanation of RAID-10 initialization. It seems like there is more going on than just zero'ing out the drives.

I have looked online, and nobody has written anything technical about RAID initialization as it seems like some of it may be proprietary; there are notes though for the high-level concepts of what each RAID-X does.

 

Thanks ahead of time!

Its probably just doing a zero of the drive. typically there is a option to skip this and just write the header data on the drive which takes less than a minute. This can also check for errors, but I don't think that's a huge issue normally.
