Storage
This section lists the storage options on your Alienware m16 R1.
Your Alienware m16 R1 supports the following storage configuration:
● Two M.2 2230 and two M.2 2280 solid-state drive slots, for computers shipped with NVIDIA GeForce RTX 4080/4090
graphics card
● Two M.2 2280 solid-state drive slots, for computers shipped with NVIDIA GeForce RTX 4050/4060/4070 graphics card
The primary drive of your Alienware m16 R1 varies with the storage configuration. The primary drive of your computer is the M.2
2280 drive where the operating system is installed.

RAID (Redundant Array of Independent Disks)
For optimal performance when configuring drives as a RAID volume, Dell 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 IO operations with block sizes larger than the stripe size will split the IO and become constrained by the
slowest of the drives. For RAID 0 IO operations where block sizes are smaller than the stripe size, whichever drive the IO operation
targets will determine the performance, which increases variability and results in inconsistent latencies. This variability is particularly
pronounced for write operations and it can be problematic for applications that are latency sensitive. One such example of this is any
application that performs thousands of random writes per second in very small block sizes.
RAID 1 (Mirrored, Data Protection) volumes benefit from higher performance when drives are matched because the data is mirrored
across multiple drives: all IO operations must be performed identically to both drives, thus variations in drive performance when the
models are different, results in the IO operations completing only as fast as the slowest drive. While this does not suffer the variable
latency issue in small random IO operations as with RAID 0 across heterogeneous drives, the impact is nonetheless large because the
higher performing drive becomes limited in all IO types. One of the worst examples of constrained performance here is when using
unbuffered IO. To ensure writes are fully committed to non-volatile regions of the RAID volume, unbuffered IO bypasses cache (for
