Hello, I'm looking for some advice on the best configuration to add more storage to my server.
I have a HPE ML110, P440ar controller, with 4LFF, 2 bays are available.
Is it better to fill the 2 bays with 4TB drives and put them in RAID1?
Or should I buy another 4LFF cage, and then buy 3 x 4TB and put it in RAID5?
From what I understand, RAID5 benefits from parity - does this parity come into effect even when reading from disk (thus almost eliminating errors?). Or is it only used when a drive fails and has to be replaced?
Cost isn't an issue (it's about 250$ for the cage and 125$ more for the extra 4tb hdd), it's worth spending some more if it saves me from a day or two of reconfiguring things a few years from now.
Thanks for your help in advance!
