In thinking about what kind of storage to buy to start working as a DIT, I've come across many articles such as this one:
which explain why RAID 5 is extremely dangerous with modern large capacity drives. Basically the bit error rate is so high on common drives (1 in 1015) that in the event of a drive failure, you are very likely to have an error during rebuild. I'd like to hear from working DIT's on here, what do you think about this? Does everyone use RAID 10? Or for the same money, use RAID 5 with SAS drives with a better error rate (1 in 1017)?
