HGST gets closer to shipping 10TB HDD

We stopped using RAID5/6 several years ago because of rebuild time and associated performance drop. Now with these massive disks we don't even use RAID10 any more! Every disk is just paired with one mirror and that's it. (RAID1)

The plan is to move to JBOD soon and just use software to store each file on 3 random disks across 3 separate servers.

That creates a substantial window during which you could lose the second drive.

I'm sure they have their reasons (I won't pretend to know every detail about their setup) but it's not a solution I would adopt in our environment.

RAID 1 rebuild time is the same as RAID 10 but if the entire thing fails you only lose one drive's info, not the entire RAID 10 array.
