I am trying to order a DELL server rack mounted PowerEdge R310 Chassis, Up to 4 Hot Plug Hard Drives and LCD.
RAID1 if i use, can i lose a disk and get back data?
- What happen if i have 2 disk as RAID1, and 1 failed? System keeps running? Can i then simply add a new disk and it continue? Or i need to shutdown the service and start new setup?
RAID0 if i use, and disk is damage, can i get back data?
- performance issue (not important for my case)
RAID5 seems more advanced, but expensive, which assure both can be done.
- best but i just need RAID1 features (safety)
I would like to go with RAID1 or RAID5, do i really need NAS?. Please advise.
