    VessRAID 1740s, 1840s Product Manual RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple physical drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive.

  • Page 233: Raid 1 - Mirror

    Chapter 8: Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of physical drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner.

    Chapter 8: Technology Background RAID 5 – Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives. Generally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level.

    Chapter 8: Technology Background RAID 10 – Mirror / Stripe Mirror/Stripe combines both of the RAID 0 and RAID 1 logical drive types. RAID 10 is similar though not identical to RAID 0+1. It can increase performance by reading and writing data in parallel while protecting data with duplication. The data on one drive pair is mirrored together, then striped over a second drive pair.
