USB 3.0 1 TB External Hard Drives

External hard disk drives are a convenient way to store large amounts of files securely. A 1 TB external HDD equipped with USB 3.0 connectivity provides plenty of capacity for most applications and allows users to access it quickly.

Why External Storage?

External hard drives are a relatively inexpensive and very compact way to store large amounts of data. Their portability makes it easy to share that data with other people, even very large files that would be impractical to send over the Internet. External storage is also a very popular option for keeping backups, and a 1 TB external hard drive is large enough to back up every single file on many laptops. The standard level of storage on many laptop computers can also run out quite quickly when you are working with large files. Using an external hard drive for extra space is much more convenient than replacing the internal hard drive, which may be difficult or even impossible depending on the model.


A terabyte is a unit of disk storage capacity equivalent to 1000 megabytes. Once thought to be an unimaginably large amount of storage, many new laptop computers now come with a 1 TB hard drive. How much this storage space is in practical terms will depend on your usage. A terabyte is enough for around 17,000 hours of music. If you are saving a lot of high-resolution pictures or 4K video, though, a terabyte can vanish very quickly.

USB 3.0

USB 3.0 is a connectivity standard for computers and other electronic devices. It was first announced in 2008 to replace the previous USB 2.0 standard. The SuperSpeed USB specification delivers a maximum data transfer rate of five gigabits per second, or 625 megabytes per second. Compared to USB 2.0, which could only manage a slower 60 megabytes per second, this makes it much quicker to transfer large files from one device to another. An external USB 3.0 hard drive is much more suitable for storing high-resolution images or video than a USB 2.0 portable hard drive.

HDD or Solid State

Most external hard drives are HDDs, meaning that they use a moving arm to read and write data on a rotating magnetic disk. Solid state drives are a relatively new technology that dispenses with the moving parts, relying instead on large amounts of flash memory. The lack of moving parts allows solid state drives to achieve much higher read and write speeds. They also have the advantage in both form factor and durability. On the other hand, solid state drives are typically more expensive than their rotating-disk counterparts. This is particularly true of high-capacity models like solid state 1 TB external hard drives.
