    Western Digital has this week introduced its new 10TB datacenter-class helium-filled WD Gold hard drive. This drive, according to WD, boasts higher performance compared to its predecessor combined with lower power consumption. The new WD Gold 10 TB will be Western Digital’s flagship HDD for data-centers and will compete against hard drives of similar capacity from Seagate and HGST.

    The WD Gold 10 TB drive (WD101KRYZ) shares the hermetically-sealed 3.5” platform with the WD Gold 8 TB, which was introduced earlier this year. The new drive is based on multiple PMR (perpendicular magnetic recording) platters, features a 7200 RPM spindle speed, a double-size 256 MB DRAM cache and is based on the SATA 6 Gbps interface (right now, WD does not offer Gold HDDs with SAS interface). Just like the other WD Gold HDDs, the new 10 TB model was designed for a variety of server applications, including small to medium-scale machines, as well as rack-mount data center servers and storage enclosures. The drive is promoted as being optimized for RAID environments and supports enhanced RAFF technology that protects against vibration (by monitoring linear and rotational vibration in real time) as well as head positioning system with two actuators, which increases positional accuracy. In addition, the WD Gold 10 TB also supports time-limited error recovery technology (TLER), which prevents drive fallout caused by extended HDD error recovery processes.
