Use the Raid 5 and create several Partitions. Raid5 has the best combination of Read/Write Speed
mail storage is about 50/50 read/write, maybe even more writing that reading, due to all the logging and deleting. RAID5 is the slowest RAID for writing, so it's the slowest RAID for mail sotrage.
RAID5 is fine for database work that is 90/10 read/write.
RAID1 is the best, fastest for mail i/o while providing 100% redundancy.
from a backup, i.e. increased down time. Raid1 has slower right times.
I've never seen RAID1 writing be slower than RAID5. what's your reference?
Which RAID makes no difference in speed if the disk system isn't stressed/congested.
