Overview
The MZ1L21T9HCLS-00A07 is the 1.92 TB M.2 22110 build of the Samsung PM9A3 Gen4 enterprise SSD. It exists because boot volumes have grown: container runtimes, hypervisor images and system logs routinely need more than a terabyte, and a mirrored pair of M.2 devices is still the cheapest way to get redundant OS storage without spending two front drive bays.
At 1.92 TB the drive also has enough write bandwidth headroom to double as a local scratch or logging volume, with 1,000K IOPS random read and 3,100 MB/s sequential write at a 1 DWPD five-year rating.
Note the 22110 length requirement - the enterprise M.2 slot on current server motherboards is laid out for 110 mm modules.
Key Benefits
1.92 TB in M.2 22110: mirrored OS volumes without spending drive bays. 1,000K IOPS read: doubles as local scratch or log storage. 3.5 PBW: published endurance at 1 DWPD over five years. OCP 1.0 compliant: hyperscale boot-drive specification.
Applications
Mirrored server boot devices, hypervisor system volumes, container image and runtime storage, local logging and scratch volumes, and edge deployments with M.2-only storage.
