RAID 10 – M
IRRoR
+ S
tRIPe
Stripe combines both of the RAID 1 and RAID 0 logical drive types. RAID 10 can increase performance
by reading and writing data in parallel or striping, and duplicating the data, or mirroring.
PROMISE implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe
over a second pair of disk drives. Some applications refer to this method as RAID 0+1.
Advantages
Disadvantages
• High Read data transaction rate
• Medium Write data transaction rate
• Good aggregate transfer rate
• Safest RAID level, except for RAID 60
• High disk overhead – equivalent of two
drives used for parity
• Slightly lower performance than RAID 5
Recommended Applications for RAID 6:
• Accounting and Financial
• Database servers
• Any application requiring very high availability
PROMISE RAID 10 starts with a data stripe, then mirrors it
