⟩ What are the advantages of RAID 1, 1/0, and 5. What type of RAID setup would you put your TX logs?
Transaction logs write sequentially and don't need to be read at all. The ideal is to have each on RAID 1/0 because it has much better write performance than RAID 5.
RAID 1 is also better for TX logs and costs less than 1/0 to implement. It has a tad less reliability and performance is a little worse generally speaking.
RAID 5 is best for data generally because of cost and the fact it provides great read capability.
