320 GB Internal Hard Disk Drives: Space for More Content

Hitachi is a reputed provider of internal hard drives and has a long history developing and producing these important computer components. In fact, the company was the first to introduce a 1 TB internal hard drive back in 2007. A 320 GB internal HDD, in particular, can add useful storage space to most computers.

What Types of Internal Hard Drives Should Users Choose?

There are several important factors to consider, including the following:

  • Type of Interface: Older computers used an interface called the IDE (or PATA) interface, but most newer computers use the SATA interface. However, SATA has evolved, so depending on the computer in question, users can choose from SATA I, II, or III drives. Another type of interface is SAS, or Serial Attached SCSI. This interface is often used in servers.
  • Hard Drive Speed: Internal hard drives feature spinning magnetic platters. The speed at which these platters spin is indicated in RPM. A drive that spins at 7200 RPM will be able to read and write data faster than one that spins at 5400 RPM.
  • Physical Size: Hard drives come in two common sizes: 3.5 inches, and 2.5 inches. Desktop drives feature the 3.5-inch form factor, while the smaller 2.5-inch size is used for laptop drives. It is possible to use a smaller drive in a desktop with adapters.

How Much Can a 320 GB HDD Store?

It is not possible to keep on adding internal hard drives indefinitely every time a user needs more storage space. Therefore, it is important to choose a hard drive that can safely store all the data a user needs to store.

  • Documents: Word processors and spreadsheet programs rarely create very large files. Assuming an average size of 2 MB for a file, a Hitachi 320 GB drive can store over 160,000 files.
  • Multimedia: Audio, video, and images are larger than other documents. One gigabyte of space can store about 200 MP3s and about half the number of quality JPEG images.

Are Solid State Drives a Better Option?

Solid state drives (SSDs) are a newer type of computer storage that use flash storage instead of magnetic platters. They offer some advantages over hard disk drives.

  • Speed: As there are no moving parts involved in SSDs, they read and write data much faster than traditional disk drives.
  • Size: As of 2018, it is easier and less costly to find traditional HDDs in large capacities.
  • Cost: The cost per GB of traditional disk drives is lower than the newer SSDs. Traditional hard drives are a good option for users who do not need the extra speed, but do appreciate the extra space.
