RAID

For optimal performance when configuring drives as a RAID volume, Dell recommends drive models that are identical.

Table 13. RAID (Redundant Array of Independent Disks)

Type

RAID 0

RAID 1

RAID 5

RAID 10

Precision 7865 Tower supports RAID with more than one hard drive

configuration.

Care must be taken to match not only the drive vendor, capacity, and class, but also the specific model. Drives from the same

vendor, with the same capacity, and even within the same class, can have very different performance characteristics for certain

types of IO operations. Thus, matching by model ensures that the RAID volumes are comprised of an homogeneous array of

drives that will deliver all the benefits of a RAID volume without incurring the additional penalties when one or more drives in the

volume are lower performing.
