The 4TB Re Datacenter 7200 rpm SATA III 3.5" Internal HDD from WD delivers durable capacity storage for high-availability deployments. With an error tolerance of <1 in 1015, an MTBF of 2 million hours, an AFR of 0.44%, and 600,000 load/unload cycles, it helps provide durability and 24x7x365 reliability in tightly packed vibration prone multi-drive systems. In addition to its performance and robust design, its capacity of 4TB makes this drive well suited for heavy workload environments, cloud storage, RAID arrays, external storage arrays, date warehousing, and mining applications.
This WD Re Datacenter drive operates using a SATA III 6 Gb/s interface, a 64MB cache, and a rotational speed of 7200 rpm, all of which help to ensure uninterrupted data transfers with a sustained rate of up to 171 MB/s. It is also equipped with vibration protection, Dual Actuator technology, StableTrac technology, a multi-axis shock sensor, TLER technology, NoTouch Ramp Load technology, dynamic fly height technology, and dual processors. To further help ensure reliable operations, a thermal extended burn-in test is performed.
Designed for Heavy Application Workloads
This drive is designed to handle up to 550TB per year in heavy application datacenters with high workload capabilities. Up to 6 Gb/s transfer rates and sustained sequential data rates of up to 171 MB/s help deliver performance and reliability
Designed for Quality and Reliability
With up to 2 million hours MTBF, this drive delivers durability and a high level of reliability for 24x7x365 operation in demanding storage environments
Enhanced RAFF technology includes electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a performance improvement in high vibration environments
Dual Actuator Technology
Dual Actuator Technology is a head positioning system with two actuators that helps improve positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles, while the secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy (2TB and above)
In addition to being RoHS compliant, this drive is built with halogen reduced components
Self Encrypting Drive (SED) Option
The SED option provides a 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 and also the Security Feature Set which utilizes the Secure Erase Unit (SEU) enhanced mode bit. Please bear in mind that SED drives may require TCG-compliant host or controller support. SED drives may not be available in all countries
Multi-Axis Shock Sensor
The multi-axis shock sensor automatically detects subtle shock events and compensates to help protect data
RAID-Specific, Time-Limited Error Recovery (TLER)
TLER helps prevent drive fallout caused by the extended hard drive error-recovery processor common to desktop drives
NoTouch Ramp Load Technology
The recording head never touches the disk media, helping to ensure significantly less wear to the recording head and 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 increased reliability
This drive has twice the processing power to help maximize performance
