HGST Internal Hard Drives

Browse the wide selection of HGST internal hard drives available at Staples® to upgrade your PC with a high-performance storage unit. This brand makes hard drives for desktop and mobile computers as well as servers, network-attached storage devices, TVs, portable media players, and vehicles. It offers them in different sizes, speeds, and capacities.

Choose the Right HGST Internal Hard Drive for Your Device
The two most common form factors for internal hard drives are 3.5 and 2.5-inch disks. The bigger 3.5-inch disk is for desktop computers and servers. While 2.5-inch hard disk drives are popular storage units for laptops, you can also find them in some desktop PCs, video game consoles, portable music players, and even enterprise storage devices. The 3.5-inch hard disk size is capable of higher storage capacities. It can house as many as 8 platters while 2.5-inch units can only hold a maximum of five platters. HGST's enterprise hard drives make use of the higher platter count of 3.5-inch disks to offer more storage capacities.

Key Features to Consider When Comparing HGST Internal Hard Drives
Besides physical size and storage capacity, you should also consider speed and ruggedness when shopping for internal hard drives. Choose a rugged unit, like the HGST Travelstar® hard drive, for your mobile devices. This 2.5-inch disk has a slim profile that allows it to fit inside thin and light laptops. It can also withstand rough handling better than a regular internal hard drive. The two factors determining the real-world speed of a hard drive are its rotational speed and interface type. The higher the spin speed of a hard disk, the faster it accesses stored data. A drive with a speed of 5400 rpm is fast enough for a personal computer. Enterprise-grade storage applications, gaming PCs, and work computers running resource-intensive applications need hard drives that can spin at 7200 rpm or faster.

What Kinds of Interfaces Do HGST Internal Hard Drives Have?
HGST drives use SATA and SAS interfaces. The SATA or Serial ATA interface offers improved performance, faster transfer rates, and reduced interference when compared to the PATA interface it replaced. SAS or Serial Attached SCSI delivers even faster data transfer speeds and is compatible with SATA. HGST offers SATA and SAS versions of its enterprise drives. Its SATA drives can achieve speeds as high as 6 Gbps while its SAS drives are capable of double that speed.

Does Cache Size Affect the Performance of HGST Internal Hard Drives?
Yes. Cache or disk buffer is a physical part of a hard drive used like RAM. It stores frequently accessed data to make retrieval faster. This section is faster than the rest of the hard disk and varies in size from 8MB to 256MB. While having more than 8MB in cache size does not produce a speed boost, it does improve the drive's overall performance.

Can You Use an HGST Internal Hard Drive as an External Storage Unit?
Yes. Some models, such as HGST's Travelstar hard drives are ideal for re-purposing as external hard drives. These slim 2.5-inch disks are also lightweight. Other qualities that make them perfect for this purpose include 32MB caches, a rotational speed of 7200 rpm, and a SATA interface that can deliver data at 6 Gbps.
