My current VMware has 4 HDD running in RAID-5, with one datastore on the VM server.
I will add 4 more HDD to the server. Just wonder whether there is any difference in performance if
1. configure 4 new HDDs with separate RAID5 with a new datastore
2. extend the current RAID with "4 HDDs" and extended the size of the existing datastore.
Any comment ? Tks
