RAID - Two Arrays for Server? Array 1 for Windows Host and Array 2 for VMs and Data?

This is what we do.

Option 3.
Hypervisor on satadom or small SSD drive.
Performance storage array with SSDs. Raid 1 or 10.
Capacity storage array with 3.5" HDDs. Raid 1 or 10.

Each VMs gets the kind of storage it needs.

RAID1 is default for the arrays.

RAID10 is only used when the capacity is needed (always as few drives as possible).

Right now I'm prepping a RAID 1 array 2x16TB that will go into one of our hosts.
md4 : active raid1 sdm[1] sdl[0]
      15625748288 blocks super 1.2 [2/2] [UU]
      [>....................]  resync =  0.6% (99811008/15625748288) finish=1322.2min speed=195699K/sec
We'll see how long it takes. Supposedly around 23 hours.

Same here.

So you've moved to SSD with RAID 1 or RAID 10, no more RAID 5?
