Internal Hard Drives & Storage

An internal hard drive is any storage drive that can permanently hold data on a computer as opposed to temporary storage, like RAM, and is mounted on the inside of a computer system. The technical name for hard drives is hard disk drives (HDD). SSDs or solid state drives are often included when discussing internal hard drives because SSDs serve a similar purpose. Internal hard drives are necessary for the installation of an operating system for a computer.

The dimensions of an internal hard drive are typically 3.5” or 2.5” wide, which make them perfectly sized for desktop and laptop installations respectively, though many desktop PC builders will still use 2.5” hard drives for space and aesthetic reasons. While internal hard drives are intended to mounted inside a computer case, they can also be mounted in a hard drive enclosure to become an external hard drive. Internal hard drives can hold the most data for the least expense of all the storage options, reaching upper limits of multiple terabytes.

Internal hard drives can also be called “mechanical hard drives” due to the physical mechanism inside the drive. To illustrate, the internal setup comprises a stack of several spinning platters, a spindle, an actuator arm and a read/write head. The read/write head moves around the platters to either read/write data using electromagnetism to either change polarity in sections of the platter when writing or to sense polarity when reading.

Finally, internal hard drives connect to a motherboard via a number of formats, including SCSI, ATA or SATA ports. Internal hard drives require external power to operate.

The best internal hard drive manufacturers from around the world have partnered with Newegg, allowing Newegg to offer its customers the widest selection of internal HDDs, 1TB hard drives, laptop hard drives, and hard drive accessories. Brands include: Western Digital, Seagate, HGST, Toshiba, and more. If you’re looking for storage capacity, speed or both for your desktop PC or laptop, Newegg has exactly what you want.

Depending on your needs, you may need different accessories to maximize the performance of your internal hard drive, prevent the degradation of your HDD, or expand the functionality of your internal hard disk drive.

Hard Drive Cooler: Heat always degrades performance of any machine; internal hard drives are affected the same way. However, internal hard drives are especially important because they hold your important data. Internal hard drive coolers come in the form of fans and heatsinks.

Controller: Depending on how old your system is and your particular use case, you may not have enough internal hard drive connectors on your motherboard. For those times, a controller may need to be installed into an expansion slot to create more ports. Controller cards can also add other connector formats to your system, like SCSI.

Hard Drive Enclosure: Need to take your internal hard drive with you and be able to use it without installing it? A hard drive enclosure is the perfect solution. Don’t settle for half measures with a USB stick. Take all of your data!

Compatibility is the top concern when selecting an internal hard drive for your system. Make sure your internal hard drive physically fits inside your system. An internal 3.5” HDD will not fit inside a laptop; you will need a 2.5” laptop hard drive. You will also need to make sure that the hard drive has compatible connectors for your system, like SATA, ATA or SCSI.

Next, make sure the internal hard drive has enough storage capacity. Obviously, smaller files like documents don’t need much room, but larger files, like videos, need a lot of room. For large files, consider buying large 1TB internal hard drives. You may even need multiple hard drives.

Lastly, examine your particular use case for your hard drives. Today’s hard drives are sophisticated enough to specialize in different tasks, such as gaming, file serving, media storage and more. For the best experience, get the hard drive type that matches your needs.

What is a hard drive?

A hard drive is any storage drive that has never had any data written to it before. New internal hard drives typically come in a sealed electrostatic bag to prevent any electrostatic discharge from damaging the hard drive. New external hard drives are usually installed in some kind of housing that protects the drive from damage, so these models are usually shipped in consumer packaging.

What companies are hard drive manufacturers?

Hard drive manufacturers are from various parts of the world. They include: Western Digital, Seagate, HGST, Toshiba, ASUS, IBM, Fujitsu, DELL, Samsung, SuperMicro and more. Fortunately, all of the popular internal hard drive manufacturers have partnered with Newegg, offering their customers the widest selection of hard drives for every type of use case.

What is a TB hard drive?

A TB hard drive is any storage drive that has at least a one terabyte storage capacity. A terabyte (TB) is currently the highest unit of measurements for single consumer-grade hard drives. Internal TB hard drives are commonly used for storing large media files, installing video games on, saving surveillance video, serving files, and more. Due to the recent affordability of TB drives ever since SSDs have begun dropping in price, TB drives have become a staple in any computer’s build and the minimum considered capacity for storage drives by most PC builders.
