WD Red Pro 20 TB CMR NAS drive
The WD Red Pro WD201KFGX is a 20 TB 3.5-inch internal hard drive built for multi-bay NAS enclosures. It spins at 7200 RPM with a 512 MB cache and uses conventional magnetic recording on a SATA 6.0 Gb/s interface. The drive is rated for up to 300 TB per year workload and includes NASware 3.0 firmware for RAID optimisation.
Suits 24-bay RAID arrays.
This drive targets commercial and enterprise NAS systems that run 24/7 in RAID configurations of up to 24 bays. Its vibration sensors and dual-plane balance control are calibrated for dense, multi-drive chassis. Builders assembling a single-drive workstation or a portable USB enclosure will not benefit from these enterprise-grade features.
300 TB yearly workload rating decides fit
The 300 TB per year workload rate is the key specification that determines whether this drive matches the intended environment. Systems that continuously write and rewrite large datasets across many bays need this endurance ceiling; lighter workloads do not require it.

商品問答
Will this 20TB SATA drive work in my older 4-bay NAS that only supports drives up to 10TB?
The drive uses the standard SATA 6.0Gb/s interface, so it connects physically, but the NAS firmware must support 20TB volumes; check the manufacturer's compatibility list for your specific model.
How can I verify the 7200 RPM mechanism and 512MB cache are performing correctly after installation?
Run the NAS vendor's built-in SMART test or Western Digital's Data Lifeguard Diagnostic; both report spindle speed, cache size and health attributes to confirm the drive matches its specifications.
Does the retail box include mounting screws or a SATA cable, or do I need to buy them separately?
The drive ships as a bare 3.5-inch unit; mounting screws and SATA data/power cables are not included and must be sourced from your NAS chassis or purchased separately.
