WD Internal Hard Drives

Internal storage makes it easy to keep important documents close at hand, minimizing the amount of time that WD® internal hard drives need to retrieve files and programs. Compare hard drive models to find one for every laptop and desktop model.

Compare Space Options on WD Internal Hard Drives
Capacity is one of the most important factors in a hard drive purchase. Those who rely on cloud storage or off-site data storage don’t need as much space as those who need to have all of their files and games immediately accessible. Many mobile drives have capacities ranging from 500GB to 1TB. Smaller models start at 250GB. Some of the largest WD drives fit between 6TB and 8TB, offering a significant upgrade from many laptop and desktop internal hard drives.

WD Internal Hard Drives Offer Various Speed Choices
The internal hard drive’s processor determines how quickly it runs and how much data it can transfer. Some WD hard drive models offer dual-core processors. A single-core processor is sufficient for casual users. Users who rely on their computer for data-heavy tasks like surveillance, gaming, and multitasking benefit from the added speed of a dual-core processor. The higher a drive’s data transfer rate is, the more rapidly a computer accesses programs and documents.

Choosing the Right Interface for WD Internal Hard Drives
Hard drives communicate natively with specific bus types built into laptops and desktops. Choosing a hard drive that’s compatible with the computer’s interface ensures that the drive and computer communicate efficiently. WD internal hard drives use the SATA interface.

How Can Users Check If Their Computers Fit WD Internal Hard Drives?
The interface is an important part of compatibility, but don’t forget to check the measurements of a hard drive. A small hard drive fits into a larger slot with the help of an adapter, but there is no way to make a drive fit into a smaller storage slot. The 3.5-inch form factor is standard for desktop computers. The 3.5-inch form factor model has a width of 4 inches and a height of 5.79 inches. Drives designed for mobile devices typically have a 2.5-inch form factor. This model measures approximately 2.8 inches x 3.9 inches.

Do WD Internal Hard Drives Add to Existing Storage or Replace a Drive?
Internal drives aim to replace the hard drives that are built into laptops and desktops. With a hard drive enclosure, users convert internal hard drives to external hard drives. With this feature, internal drives are ideal for backup storage.

Are Specialized WD Internal Hard Drive Models Available?
With standard and mobile hard drives, it’s easy to choose a drive for any type of computer. Additional drive options meet specific needs, such as the need for surveillance video backup. The WD surveillance hard drive tolerates extreme temperatures to accommodate constant outdoor surveillance. Surveillance drive models support a workload that is 3 times larger than the standard desktop drive, which permits them to support up to 64 surveillance cameras simultaneously. With high-capacity drives, users store more footage and easily back up video streams.
