About the ST16000NM002G
ST16000NM002G is Seagate's enterprise 16TB 7200 RPM dual-port SAS 12Gb/s 3.5-inch hard drive in the Exos X16 product line. Built on a 9-disk helium platform, it delivers sustained transfer speeds up to 261 MB/s with dual-port SAS multi-path redundancy and 2.5 million hours MTBF. It is engineered for mission-critical enterprise SAN storage arrays, high-availability clustered file systems, and enterprise shared disk shelves.
Compatibility
Requires 3.5-inch drive bays connected to a 12Gb/s or 6Gb/s SAS host bus adapter, RAID controller, or SAS expander. It CANNOT connect to SATA-only controllers. Supported in enterprise SAN arrays and dual-controller server backplanes from Dell, HPE, Lenovo, and NetApp. Supports FastFormat 512e and 4Kn sector sizing.
How to identify a genuine unit
The drive displays an Exos X16 label with model ST16000NM002G, part number 2KK203-002, and 12Gb/s SAS interface branding. In StorCLI or MegaRAID software, it reports as a dual-port SAS enterprise drive with Seagate signed firmware. OEM variants carry vendor part stickers.
Buying used
Inspect SCSI defect logs and verify whether the drive was formatted with proprietary 520-byte sectors by an OEM SAN vendor (such as EMC or NetApp). Standard servers require reformatting to 512-byte sectors using Linux sg_format. Verify that both physical SAS ports establish link cleanly.
