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 the slowest of the drives. For RAID 0 I/O operations where block sizes are smaller than the stripe size, whichever drive the I/O operation targets determine the performance, which increases variability and results in inconsistent latencies. This variability is pronounced for write operations, and it can be problematic for applications that are latency sensitive. One such example is any application that performs thousands of random writes per second in small block sizes. 20 Specifications of OptiPlex Micro Plus 7020

RAID (Redundant Array of Independent Disks)
For optimal performance when configuring drives as a RAID volume, Dell Technologies recommends drive models that are
identical.
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
the slowest of the drives. For RAID 0 I/O operations where block sizes are smaller than the stripe size, whichever drive the I/O
operation targets determine the performance, which increases variability and results in inconsistent latencies. This variability is
pronounced for write operations, and it can be problematic for applications that are latency sensitive. One such example is any
application that performs thousands of random writes per second in small block sizes.
