I have installed the Intel RSTe software/drivers, and I'm in the process of creating a RAID 1 array with two equal sized (8TB) drives on the a Z620. These drives are on the Intel C600+/C220+ chipset SATA RAID controller.
A few questions:
A) Is there any performance hit for running RAID 1 as set up this way?
B) If one of the volumes goes bad, what's the process to fix things?
1) Delete the RAID volume
2) Remove the bad drive
3) Replace the bad drive
4) Recreate the RAID 1 volume?
If one of the disks goes bad, will the RAID contoller continue to use the good drive until the volume is deleted and the bad drive is replaced?
Is there anything funky about these two drives in the RAID 1 array? That is, could i pull one (assuming it's good) and use it in another computer as -is. Or would i have to delete the volume first to use it?
Thanks.

Yes I've looked at that stuff.
That's why I am asking here.
That stuff is mostly very out of date (see incorrect max drive size) and don't address real world questions like actual performance etc.
Looking for an answer from someone willing to actually answer the question based on experience.

there is nothing out of date in the links i provided, the process/hardware to setup/maintain a array has not changed since they were written
and as for drive sizes, the newer drive sizes 6/8/10TB are handled the same way on the z620 as the smaller sizes with a limit on MBR "Legacy" boot drives and just about unlimited sizes on UEFI/GPT setups
you want to learn? then start reading...................................
last your questions about performance.....when asking this type of question you need to state the OS, and if 32 or 64bit the current build, the type of files being xfered (size does matter) and the filesystem used and the application being used and the drive model(s) being used without the above information no valid comparisions can be made
