I have been looking into RAID. I have found out that there is RAID0 and RAID1. Which is better?
it depends whether you are concerned more about performance or protecting your data, generally RAID0 is striped, which means the array reads of writes from one HDD and the next piece of info is read of written to the other HDD this effectively doubles the performance, & generally RAID1 is mirrored, which create a mirror image of the HDD this config uses standard performance, but neither RAID 0 or 1 use any kind of fault tolerance, so, if a HDD dies so does your array
Alright, I back everything up onto an external, so probably RAID0, huh. Whcih would you prefer?
neither 0 or 1 because you can get better performance out of a stripped RAID setup but neither RAID 0 or 1 have any fault tolerance (parity drive) so if 1 HDD fails you lose the array personally i'd prefer RAID 2, 3, 4 or 5 with at least 1 or more fault tolerance disks
Alright, so have looked into it some more and RAID5 doesn't look so bad. Say I have it in RAID5 and one of the 3 drives fails, I replace it and how do I get the lost information back? Does it just do it for me or do I have to do something?
Separate names with a comma.
