Reliability With a MTBF of up to 2.0 million hours, WD Gold hard drives deliver reliability & durability for yearly operation (24x 7x 365) within demanding storage environments. Disk Utilities & Migration Tools Acronis True Image WD Edition can clone drives as well as backup your operating system, applications, settings, & all of your data, while also having the ability to wipe any data you no longer need securely. You can quickly & easily deploy a new hard drive to your PC or laptop & automatically migrate your operating system, applications, & 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 & 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. It comes armed with Helio Seal Helium technology that enables up to 26 percent lower power consumption when compared to a standard drive. With an error tolerance of
