Magnetic disk-based storage for inside your computer or data center, delivering a cost-effective, reliable way to manage large data sets and content libraries.
Magnetic disk-based storage for inside your computer or data center, delivering a cost-effective, reliable way to manage large data sets and content libraries.
An internal hard drive is installed inside a desktop, laptop, server, or NAS system to store your operating system, applications, and files. It provides high-capacity, reliable storage for everything from everyday computing to managing large data sets, video surveillance footage, or shared network access. Internal drives are a cost-effective solution for long-term, always-on storage in both personal and professional environments.

Handle up to 64 single-stream HD cameras8, helping you scale faster and smarter.
Designed for public and private cloud environments, our internal HDDs for data centers help you store massive amounts of data reliably, cost effectively, and energy efficiently.
HelioSeal, which seals helium inside our hard drives, allows more disks, quieter operation, and low power usage.
The latest in HDD technology, OptiNAND adds a flash layer to offload expanded metadata, reducing DRAM need.
A breakthrough in HDD tech, eAMR enables higher areal density through increased bits per inch on HDD tracks.
Higher performance. Growing capacities. Even greater reliability. From integrating iNAND embedded flash devices to sealing drives with helium to reduce friction, our most advanced hard drives elevate traditional HDD architecture to push data storage further.
Platters: The disks inside the drive that spin and store data.
Read/Write Heads: Hover just above the platters, reading and writing data.
Actuator: Moves the read/write heads across the surface of the platters.
Spindle: Holds the platters in place and allows them to rotate.
Voice Coil Motor (VCM): Repositions the actuator with high precision and speed.
Data Connector: The port where the data cable connects the HDD to the computer.
Power Connector: Delivers power to the drive, usually from the computer.
Internal SATA HDDs:
Internal SAS HDDs:
OptiNAND is Western Digital’s proprietary technology, integrating iNAND embedded flash devices in hard drives (HDD) to create a flash-enhanced drive. With OptiNAND, an HDD’s key housekeeping functions can take advantage of the speed and capacity of iNAND, freeing up more capacity and improving the overall drive performance.

CMR:
SMR:
UltraSMR fuses hardware, controller, and read channel technologies with proprietary firmware and algorithms to significantly expand the capacity advantage that Shingled Magnetic Recording (SMR) provides over Conventional Magnetic Recording (CMR).
Collectively, these technologies enhance the capacity of an SMR drive by an additional 10%, allowing a gain of 20% over a traditional CMR drive.

Western Digital’s HelioSeal technology hermetically seals HDDs and replaces the air inside with helium, which is one-seventh the density of air. The less-dense atmosphere inside the drive allows for dramatic increases in efficiency, reliability, and capacity compared to conventional, air-filled hard drives.
eAMR technology uses an electric field to reduce the magnetic resistance of a recording medium, making it easier to write data to a hard drive disk. This technique aims to increase the storage density of HDDs, which is critical as we continue to generate more and more data.
ePMR is an evolution of traditional perpendicular magnetic recording, enhanced with electric fields. It can improve:
