About the ST22000NM001E
ST22000NM001E is Seagate's ultra-high-capacity 22TB 7200 RPM SATA 6Gb/s enterprise hard drive in the Exos X22 series.

It is designed for massive hyperscale data centers and object storage pools requiring maximum petabyte density per rack unit.
Compatibility
Compatible with 3.5-inch LFF enterprise drive bays in modern server platforms and dense storage disk shelves. Connects to SATA 6Gb/s host ports, SAS/SATA HBAs, or hardware RAID controllers. Verify that host HBA firmware supports 22TB drive capacities.
How to identify a genuine unit
The label bears Seagate Exos X22 branding, model ST22000NM001E, part number 3AP103-002, and 22TB capacity with 512MB cache notation. In Linux, smartctl, and MegaRAID storage utilities, the drive identifies as ST22000NM001E with official Seagate firmware and standard 512e sector format.
Buying used
At 22TB, verify that SMART attributes show zero bad sectors and that helium pressure is 100 percent. Confirm that power-on hours and load/unload cycles are reasonable for the asking price. Ensure the seller includes a return warranty and packages the drive in protective anti-static clam shells.
