RAID

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

Table 1. RAID (Redundant Array of Independent Disks) The table provides more details of supported RAID configurations on Precision 7865 Tower:
Type	Supported
RAID 0	Yes
RAID 1	Yes
RAID 5	Yes
RAID 10	Yes

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.
