Western Digital Launches 12TB Gold Hard Drive To Consumers

1 post in this topic

Western Digital has a new mechanical hard drive for your treasure trove of digital data. Utilizing fourth generation HelioSeal technology and eight PMR platters to fit 1.5TB of data per platter, the WD121KRYZ has a capacity of 12TB and features quite a few enterprise technologies to improve reliability and reduce data loss.

The WD Gold 12TB drive is an eight-platter 3.5" drive spinning at 7200RPM paired with 256 MB of cache and featuring a SATA III interface. The helium sealed hard drive uses a dual stage actuator head positioning system that and adjust the fly height of the read-write head in real time. Enterprise focused features include RAFF to monitor and correct linear and rotational vibrations and TLER to protect the integrity of a RAID array. The vibration monitoring Is overkill for a desktop PC or even a NAS, but can be useful in a datacenter environment where hundreds of drives are packed together. The time limited error recovery technology ensures that bad sectors do not cause a RAID rebuild to fail (and Allyn has a more in-depth explanation here).

The WD Gold 12TB is built for continuous operation with an annual workload rate of 550TB running 24/7 with a 5-year warranty and 2.5 million hours MTBF. The maximum sustained transfer is 255 MB/s. The digital hoarder’s dream is available for $521.99 from Western Digital which works out to $0.0435 / GB. If you do not want to wait for a Red Pro 12TB variant (there does not appear to be one available and WD only recently launched 10TB models), the Gold series drive might be a good option with a better warranty and lower error rate.
