18 TB Enterprise SATA Drive

The Western Digital P37677-001 is an 18 TB 3.5-inch hard drive built for enterprise servers, storage arrays and workstation computers. It runs at 7200 RPM on a SATA 6.0 Gb/s interface with a 512 MB cache and CMR recording technology. The helium-sealed design supports sustained high-throughput workloads in compatible Gen8 and Gen9 ProLiant systems.

Suited For Bulk Storage Arrays

This drive suits administrators expanding Gen8 ProLiant DL, ML, BL or SL servers and HPE D3600 or D3700 storage arrays. It is not for builders who need a second card or buyers who want more storage in a laptop form factor. The 3.5-inch tray limits installation to bays that accept that specific chassis.

Sustained Transfer Up To 269 MB/s

Under continuous load the drive delivers a sustained data transfer rate up to 269 MB/s thanks to its 7.2K RPM spindle and helium platform. CMR technology keeps write performance consistent during long backup or analytics jobs. Power Disable on Pin 3 allows host-controlled power cycling without removing the tray.

商品問答

What SATA host controller or backplane do I need to run this 3.5" 18 TB drive at 6.0 Gb/s?

Any standard SATA 6.0 Gb/s controller or backplane with a 3.5" bay and SATA power connector will run the drive at full speed.

Will this helium-sealed 7200 RPM CMR drive work in my older Gen8 ProLiant DL380p or ML350e alongside existing 3.5" SATA drives?

Yes — it fits the same Gen8 3.5" tray, uses the same SATA 6.0 Gb/s interface and 512e format, so it mixes with earlier SATA drives in those servers.

How can I verify the drive is delivering its rated 269 MB/s sustained transfer rate after installation?

Run a sequential read/write benchmark (for example CrystalDiskMark or fio) on the raw device; sustained throughput should approach 269 MB/s on a 6.0 Gb/s link.
