Hello,
I have a PC with 2 sas cards with support up to 16 hhds combined, then the regular controller on the motherboard has 6 sata ports. All are configured to do standard "single jbod" configuration, like all motherboards come with as standard where each port represent one drive.
What i wonder about UnRaid is, can i configure more then one array of drives? Lets say i have 8 drives in one array, with 1 cache ssd and one parity drive, then i have another array with 4 drives and another cache ssd + parity drive, is this possible?
What can i do if unraid somehow fails, what kind of failsafes are there? I do not trust raid at all because so many things can go wrong, especially dangerous is controller card corruption starting to write corrupt data to an entire array causing corruption and mass loss of data. I prefer having my drives as single installs and then just mirror all the data of each drive to another drive based on a schedule, obviously having double the amount of drives is very expensive.
What kind of encryption is offered? Obviously some of my data is private, what kind of encryption is offered by unraid, or is unraid simply just the underlaying layer and i'll have to create containers with something like truecrypt/veracrypt on top of that?
Can i use different size drives in a raid array using unraid? One of the biggest reasons i haven't purchased a expensive nas is because i cannot utilize all the mixes drives i already own, i have drives spanning from 12tb to 4tb and anywhere inbetween, being able to utilize these drives would be a plus. Perhaps i can create an array for all my 4tb, then an array for all my 8tb, then one for my 12tb etc, or is it even possible to use mixed drives in an array?
Thanks in advance, looking forward to testing out unraid.
