Western Digital Ultrastar DC HC650 20TB Host-Managed SMR HDD

Ultrastar DC HC650: choose capacity and interface

Specialist host-managed SMR storage for compatible data-center systems and sequential workloads.

• Capacity / interface options in this listing: 20TB SATA; 20TB SAS
• Form factor: 3.5-inch internal HDD
• Interface: SATA 6Gb/s or SAS 12Gb/s; select the required option
• Recording: Host-managed SMR — requires compatible host software
• Spindle speed: 7200 RPM
• Cache: 512MB
• Manufacturer specification: 5-year limited warranty; regional eligibility and supply-channel coverage must be confirmed for the quoted unit

Compatibility check required: This is not a drop-in replacement for a conventional NAS or desktop HDD. Host-managed SMR needs a storage stack that supports zoned/sequential writes.

Business pricing & supply confirmation

Enquiry only. These options are manufacturer-documented specifications, not a claim of local stock.
