I've done lots of reading up on the topic of RAID but still can't make a fully informed decision on the best solution for me!
I have a new external hard drive dock that takes up to four drives, I have two identical 1TB drives, one other 1TB drive and a 750GB drive.
I am looking to use this box for storing all my important data (such as photos) so needs to have a fault tolerance of a minimum of one!
The box supports
BIG (Spanning or Concatenation)- No fault toleranceRAID 0 (Striped Disks)- RAID 1 (Mirrored Disks)
- RAID 10 (1+0; Striped set of Mirrored Subset)
- RAID 3 (Striped set with Dedicated Parity)
- RAID 5 (Striped Disks with Parity)
What do you think is the best? Obviously the more storage available the better, and the more speed the better and the more fault tolerance the better. Which is more important? It is an external Firewire drive, so I am thinking the speed is going to be limited by this anyway?
Many thanks!
1Isn't RAID about making your storage redundant? ... "Even if something goes wrong" is kinda incorrect-If there was corruption or an accidental file deletion on one side of the RAID 1, it'll go onto the other too. – JFW – 2010-09-26T13:02:01.787
@JFW - A RAID would pick upp a corrupt file (filesystem level corruption) but would happily allow an accidental deletion. – Nifle – 2010-09-26T13:05:37.600
