Hello all, I am very, very new to the storage realm.
I need to set up a RAID array for someone who has (4) 3 TB drives. I recently replaced a drive in the array and now it is coming up with punctured array errors and double fault errors. Based on the documentation I have read so far, I think I need to blow away the array at the controller level and restore the data from backup.
While I have the opportunity to do so, I am wondering if I should go with a different RAID level while I re-initialize the array and start from scratch. I always hear things about RAID 5 being terrible but I am not sure why people say that. Is there a better solution I should be going with in your opinion or experience? Why or why not?
Also, what causes a punctured array or double faults? Is there a way to prevent this in the future?
Thank you, responses are greatly appreciated.
Increased performance is a big consideration. This user will be storing a lot of big data files so read/write performance is high up on the list. Daily backups are taken.
