  • 1Description

The 12TB Gold 7200 rpm SATA III 3.5" Internal Datacenter HDD from WD delivers 12TB of storage capacity for high-availability servers and storage arrays. This 3.5" drive operates using a SATA III 6 Gb/s interface, a 256MB cache, and a rotational speed of 7200 rpm, all of which help to ensure a sustained rate of up to 255 MB/s. It comes armed with HelioSeal Helium technology that enables up to 26 percent lower power consumption when compared to a standard drive. With an error tolerance of <1 in 1015, an MTBF of 2.5 million hours, an AFR of 0.35%, it is well suited for small- to medium-scale enterprise environments that require a durable and reliable storage drive. In addition to the drive's performance and reliability features, Western Digital offers a 24/7 premium support line and includes Acronis True Image WD Edition cloning software.

Workload Capability
Delivering both performance and reliability to any datacenter environment, WD Gold hard drives are designed to handle workloads up to 550TB per year.
With a MTBF of up to 2.5 million hours, WD Gold hard drives deliver reliability and durability for yearly operation (24x7x365) within demanding storage environments.
Disk Utilities and Migration Tools
Acronis True Image WD Edition can clone drives as well as backup your operating system, applications, settings, and all of your data, while also having the ability to wipe any data you no longer need securely. You can quickly and easily deploy a new hard drive to your PC or laptop and automatically migrate your operating system, applications, and all of your important data.
RAID-Specific, Time-Limited Error Recovery (TLER)
Reduces the drive's fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Extended Thermal Burn-in Test
Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
Dynamic Fly Height and Dual Actuators
A head positioning system with two actuators that improves positional accuracy over the data track. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.

    WD WD121KRYZ reviews

    12TB Gold 7200 rpm SATA III 3.5" Internal Datacenter HDD is rated 4.6 out of 5 by 8.
    Rated 5 out of 5 by from It's BIG and FAST I needed a very large, fast hard drive for backing up my photo files to, so I bought the 12 TB WD Gold drive. It's big enough to hold multiple image backups of the 2 TB drive holding those files. And it's the fastest spinning platter drive I've ever seen. See the screenshot of benchmark results from CrystalDiskMark. The drive runs pretty cool, -typically at around 30 to 32 C. It is a tad noisier than, say, your typical WD Black hard drive, -you will hear some clicking from the head actuators. But I wouldn't call it the level of noise obtrusive. If you need high capacity and speed, this drive is an excellent choice.

    Rated 4 out of 5 by from Working as expected.� Runs cooler than old drives. 10 days after install. � Working as expected with no issues.� Running a few degrees cooler than the drives they are replacing.� Giving four stars instead of five because they were just installed so, no long term experience.

    Rated 5 out of 5 by from Works Great I bought this drive to store my rapidly growing number of digital images. I plugged it into my Windows 10 desktop PC, formatted it, and everything worked immediately.

    Rated 5 out of 5 by from High quality yet inexpensive I've had four drives of this model in a file server for a few months now. They work great, and thanks to the helium fill, consume lower power and thus have less heat dissipation than older drives. They are quite fast. They're built with enterprise-class hardware reliability features including the motor being secured at both top and bottom, for better vibration tolerance. They're designed to be used 24x7. I'm buying more of them.

    Rated 3 out of 5 by from WD 12 TB Gold 7200 RPM Internal Seagate HD The Fist HD that arrive was dead on arrival, luckily for the good customer service of B&H a Return Policy and a exchange was issue. Although I had to weight almost� 3 months for the exchange, For the price they charge Seagate should be more responsible for the quality of the product. I hope this one will last??? 5 Stars for B&H and 3 stars for Seagate.
