PERC H330 or Windows Storage Space on Raid 5
Hi Experts,
I'm trying to build a raid 5 array for our file server using the following:
1. Dell Poweredege R530 - server
2. Windows Server 2016 - OS
3. 3x 4TB SAS - Hard Drives
4. PERC H330 mini - embedded raid controller of dell server
But in my inquiries from diff. forums, I get these ideas:
1. There's a risk in Raid 5 using large disk, like rebuilding array takes times and probability of failing another disk during the rebuild is more likely to happen.
2. And raid controller without cache is not wise to use in a parity raid.
Since the PERC H330 is an entry-level raid card which does not have the cache. Is it more wise to use software raid in this situation or stick to using the built in raid controller?
Should I go building the Raid 5 array with 4TB disk?
What's should be the best option for this?
Thanks.

You haven't listed the disks you are going to boot the OS from, you can't boot from software RAID as the drivers that it needs to understand RAID aren't loaded until it has booted. Booting from software mirror only works because it can read everything off the primary mirror so boots without the drivers loaded.

Since they would be using DFS replication I wouldn't worry too much about RAID 5, it will cover you for bad sectors and if a disk fails just wipe the data and resync from the other server. The question remains as to whether you have separate disks to boot from.

Sorry I forgot to mention this.
The OS will use a separate raid 1 sas drive using the H330 controller. The raid 5 is only for the file storage.

DFS Replication for that much data will be _interesting_. Getting it to re-sync after a RAID 5 failure would take a long time.
I still say get another 4 TB drive and make RAID 10. You can then ditch the RAID 1 boot drive.
Better yet, make it a VM host, and make your file server a VM. I would still do RAID 10.
