18 TB SAS Enterprise Hard Drive

The Western Digital Ultrastar DC HC550 is an 18 TB internal hard drive with a SAS 12Gb/s interface, 7200 RPM spindle speed and 512 MB cache. Built on a nine-disk helium-sealed platform, it delivers a sustained transfer rate of 269 MB/s and a 2.5 million hour MTBF rating for continuous operation.

Suited for high-capacity object storage

This drive fits object storage systems that use erasure coding and need maximum density per slot. It is not suited for workloads demanding low-latency random access, single-drive desktop use, or environments that cannot accommodate a 3.5 inch SAS connection.

SAS 12Gb/s interface decides compatibility

The drive requires a backplane or controller that supports 12 Gb/s SAS signalling. Without that interface the drive cannot communicate with the host, making the SAS connection the single specification that determines whether this is the correct part.

أسئلة حول هذا المنتج

Does my server or RAID controller need a SAS 12Gb/s port for this 18TB drive?

Yes, the drive uses a SAS 12Gb/s interface and requires a compatible SAS 12Gb/s HBA, RAID controller or backplane to operate.

Will the 7.2K RPM spindle speed and 512MB cache match the throughput of my existing 7.2K RPM SAS drives?

The drive delivers a sustained transfer rate of 269MB/s and 4.16ms average latency, which is typical for 7.2K RPM enterprise SAS drives.

How can I confirm the HelioSeal platform is healthy after installation?

Check SMART attributes for reallocated sector count and temperature; the drive is rated for 2.5 million hours MTBF under normal enterprise workloads.
