WD Gold 20TB Enterprise Class Hard Drive
20TBSATA 6 Gb/s7200 RPM550 TB/yearAFR 0.35%
The WD Gold 20TB (part number WD203KRYZ) is a 3.5-inch enterprise class hard drive that spins at 7200 RPM, carries a 512 MB cache and sustains up to 285 MB/s over SATA 6 Gb/s. Western Digital rates it at 2,500,000 hours MTBF with an annualised failure rate of 0.35%, which is the reliability grade expected of datacenter and server storage rather than desktop use. Typically in stock with fast delivery across Cyprus.
Before you buy: this is a bare 3.5-inch internal drive supplied without screws, SATA cable or drive caddy. It requires a SATA 6 Gb/s port and a SATA power connector, and it is designed for a server or rack chassis with proper airflow. A drive of this class runs warmer and louder than a desktop disk and is not intended for a quiet home PC.
Best For
✓ Servers and datacenter racks
Built for continuous enterprise duty with a 550 TB per year workload rating and enterprise grade error recovery.
✓ Large RAID arrays
Rotational vibration sensors and time-limited error recovery keep the drive stable in dense multi-drive chassis.
✓ Virtualisation and database hosts
A 7200 RPM spindle with a 512 MB cache handles the mixed read and write patterns of a busy host better than a slower archive drive.
✓ Long retention backup targets
Enterprise reliability ratings make it a sound choice where the array must stay online for years without attention.
Key Features
Enterprise reliability rating
Rated at 2,500,000 hours MTBF and an annualised failure rate of 0.35%, specified for continuous 24x7 operation.
550 TB per year workload
Sized for servers that read and write constantly, roughly ten times the annual rating of a consumer desktop drive.
Rotational vibration sensors
Dual sensors measure chassis vibration and correct head position in real time, which protects throughput in a full rack.
Sustained 285 MB/s
Maximum sequential transfer rate over SATA 6 Gb/s, measured on the outer tracks.
512 MB cache
A large DRAM buffer smooths bursty write traffic before it reaches the platters.
Standard SATA 6 Gb/s
Drops into any server, workstation or NAS bay with a SATA port, with no controller or backplane change needed.

Frequently Asked Questions
Does the WD203KRYZ work in a standard PC or NAS as well as a server?
Yes. It is a normal 3.5-inch SATA 6 Gb/s drive and will run in any system with a SATA bay. Be aware that an enterprise drive is louder and warmer than a desktop or NAS drive, so it suits a rack or a well ventilated tower rather than a silent build.
Is the WD203KRYZ suitable for a RAID array?
Yes. WD Gold is designed for RAID with time-limited error recovery and rotational vibration sensors so it does not drop out of an array during a long retry. Use matched drives across the array.
What is the difference between WD Gold and WD Red Pro?
WD Gold is an enterprise datacenter drive with a higher reliability rating and is tuned for servers. WD Red Pro is tuned for NAS enclosures with NASware firmware and generally runs quieter. Both are CMR, 7200 RPM and rated to 550 TB per year.
What do I need to know before buying the WD203KRYZ?
It is a bare internal drive with no cables, screws or caddy included, and a RAID array is not a backup. Plan a separate backup copy of anything you cannot afford to lose.
Singular Expert Insight
WD Gold is the right pick when the chassis is a server rather than a desk: the value is in the reliability rating and the vibration handling, not in raw speed, and at 20TB the sequential throughput is close enough to WD Red Pro that the choice comes down to where the drive will live. If it is going into a NAS enclosure at home or in a small office, WD Red Pro is quieter for the same money. Browse our enterprise and server hard drives or, for a faster tier, our enterprise and server SSDs.
Buyer's Guide
Buy this if
You are filling a server or rack chassis and want an enterprise reliability rating with vibration handling for a large array.
Skip if
You want a quiet drive for a home NAS or desktop. WD Red Pro or WD Purple Pro will be quieter and cooler for a similar price.
Also consider
WD Red Pro for NAS enclosures, WD Purple Pro for surveillance recorders, or an enterprise SSD if latency matters more than capacity.
