constrained performance here is when using unbuffered I/O. To ensure that writes are fully committed to non-volatile regions of
the RAID volume, unbuffered I/O bypasses cache (for example by using the Force Unit Access bit in the NVMe protocol) and
the I/O operation will not complete until all the drives in the RAID volume have completed the request to commit the data. This
kind of IO operation completely negates any advantage of a higher performing drive in the volume.
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 different performance characteristics for certain
types of I/O operations. Thus, matching by model ensures that the RAID volumes are consisted of a homogeneous array of
drives that deliver all the benefits of a RAID volume without incurring the additional penalties when one or more drives in the
volume are lower performing.
OptiPlex 7090Micro supports RAID with more than one hard drive configuration.
