Hi all,
I'm building a new physical system with 14 x SSDs in RAID10.
It's been a while since I fiddled with SSDs in a corporate setup, and I guess the tech has moved quickly.
Originally, when SSDs were new, "over-provisioning" was a big thing - where 10-20% of the disk (or virtual disk in this case) is left unpartitioned to allow the system/controller to use the space for moving data blocks around (AFAIK).
So, is this approach still required and practiced? Do I still need to do it on business-grade hardware?
The OS will be RHEL and the filesystem will be Ext4.
Thank you!
Elliot
