Durable capacity storage for high-availability deployments WD Re datacenter hard drives offer up to 4 TB capacities & are available with SAS or SATA interface. With the highest error tolerance & MTBF of any capacity-optimized drive, WD Re delivers the durability & 24x 7x 365 reliability required in tightly packed vibration prone multi-drive systems. The combination of high-capacity, peak performance & robust design make WD Re drives ideal for heavy workload environments, cloud storage, RAID arrays, external storage arrays, data warehousing & mining applications. Product Benefits Industry’s highest capacity nearline drive
- Massive capacities up to 4 TB suit even the most demanding datacentre or cloud storage needs. Designed for heavy application Workloads - Designed to handle up to 550 TB per year in any heavy application datacenter with the highest workload capabilities of any WD 3.5 hard drive. Up to 6 Gb/s transfer rates & sustained sequential data rates of up to 182 MB/s, deliver performance & reliability to any datacentre environment. Designed for quality & reliability With up to 1.4 million hour MTBF, this high performance drive delivers durability & the highest level of reliability for 24x 7x 365 operation in the most demanding storage environments. Vibration Protection
- Enhanced RAFF Technology
Includes:: sophisticated electronics to monitor the drive & correct both linear & rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives. Dual actuator technology
- A head positioning system with two actuators that improves positional accuracy over the data track (s). 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. (2 TB & above) Environmentally responsible
- In addition to being Ro HS compliant, these drives are built with halogen reduced components. Self Encrypting Drive (SED) option
- Optional secure model for encrypting drives – Utilizing an AES 256 bit encryption engine for Crypto erase capability, WD supports both industry standard commands of the Sanitize Feature Set & also the Security Feature Set which utilizes the Secure Erase Unit (SEU) enhanced mode bit.* Stable Trac
- The motor shaft is secured at both ends to reduce system-induced vibration & stabilize platters for accurate tracking during read & write operations. (2 TB & above) Multi-axis shock sensor
- Automatically detects the subtlest shock events & compensates to protect the data. * SED drives may require TCG-compliant host or controller support. SED drives may not be available in all countries. RAID-specific, time-limited error recovery (TLER) - Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. No Touch ramp load technology
- The recording head never touches the disk media ensuring significantly less wear to the recording head & media as well as better drive protection in transit. Thermal extended burn-in test - Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation. Dynamic fly height technology - Each read-write head’s fly height is adjusted in real time for optimum reliability. Dual processor
