RAID (Redundant Array of Independent Disks)
For optimal performance when configuring drives as a RAID volume, Dell Technologies recommends drive models that are
identical.
NOTE: RAID is not supported on Intel Optane configurations.
RAID 0 (Striped, Performance) volumes benefit from higher performance when drives are matched because the data is split
across multiple drives: any I/O operations with block sizes larger than the stripe size splits the I/O and become constrained by
