Internal Hard Drives

Internal hard drives are core components to any PC. They are also known as “mechanical hard drives” due to the mechanical system inside each drive. The internal setup of a hard drive is composed of an actuator arm and a read/write head, a stack of several spinning platters, and a spindle. The platters spin, allowing the read/write head to move to different parts of 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.

The primary use of an internal hard drive is to permanently store data. This does not mean that the data cannot be deleted; instead, it means that unlike RAM, which acts as temporary storage, an internal hard drive hold data permanently without requiring constant power. These hard drives are also mounted on the inside of a computer system and are necessary for the installation of an operating system for a computer. Internal hard drives are also known as hard disk drives (HDD). SSDs or solid state drives are often conflated with hard disk drives, but this is incorrect. SSDs serve a similar purpose but are not the same as an HDD.

With a couple of exceptions, Internal hard drives typically measure 3.5” or 2.5” wide, which make them perfectly sized for desktop and laptop installations respectively. Some desktop PC builders will still use 2.5” hard drives for space and aesthetic reasons. While internal hard drives are usually installed inside a computer case, they can also be mounted in an external hard drive enclosure to make the hard drive a portable storage device. For the budget conscious, Internal hard drives offer the most data storage capacity for the lowest spend of all the storage options, easily providing value with TB drives.

To connect to a motherboard, internal hard drives use a number of formats, including SCSI, ATA or SATA ports. Internal hard drives require external power to operate, but will maintain the stored date even after the power is turned off.

The most popular internal hard drive manufacturers from all over the globe have partnered with Newegg, allowing Newegg to offer its customers the best selection of SATA HDDs, internal hard drives, laptop hard drives, and TB hard drive accessories. Brands include: Western Digital, Seagate, HGST, Toshiba, and more. For all of your data storage needs, Newegg’s massive selection will make sure you find the internal hard drive for your gaming, business, and personal needs.

Different users require different equipment to achieve specific goals. That’s why you may need different accessories to increase performance of your internal hard drive, prevent damage to your HDD, or add extra functionality to your HDD.

Add More Ports and Functionality: If you’re building a home server or just need to add a lot of hard drives to your computer, then a hard drive controller card is the perfect solution if you have expansion slots to spare. Also, if you need to take advantage of unique connector formats, like SCSI, you may need a controller card because your motherboard may not natively support this format.

Keep Your HDD Cool: Everyone knows that heat puts a strain on machines. That’s why machines that create a lot of heat need ways to manage the temperature. Your HDD is no different. Fortunately, hard drive coolers exist to vent heat away from your important data.Make Your HDD Portable: An internal hard drive doesn’t have to stay that way. With a hard drive enclosure, you can mount your internal hard drive inside and then use it as an external hard drive. This makes it easy to take all of your files with you wherever you go instead of having to move them to a USB drive. So convenient!

Just because all hard drives store data does not mean they are all the same. Users’ needs are very specific, so HDD manufacturers have made specialized hard drives to address those needs. File servers can benefit from specialized server drives more than they can from gaming specialized drives and vice versa. Make sure you choose the drive that best matches your specific use case.

Also, make sure the internal hard drive is physically compatible with your system. Obviously, a 3.5” hard drive will not fit inside a laptop, which is designed to accommodate 2.5” hard drives. The inverse, however, is true and you can install a laptop hard drive in your desktop, using the proper adapters if your case doesn’t accommodate smaller sized drives natively. Just make sure that your motherboard has matching connectors as the HDD you purchase.

Finally, make sure the internal hard drive has enough storage capacity for your purposes. There’s nothing worse than running out of storage space when you need it most. For large amounts of data, consider buying multiple large 1TB internal hard drives.

Can I replace a hard drive?

A hard drive replacement is any storage drive that replaces another storage drive that may have malfunctioned, failed, or is obsolete. All hard drives will eventually fail. That failure is predicted by the mean time between failures (MTBF) that hard drives are rated by. When the hard drive approaches that measurement, it is a good idea to purchase a replacement hard drive.
