• The price of large external hard drives is affordable. You can find an 8TB external hard drive at the online store for $149.76.
• External hard drives are very reliable. Generally, an external hard drive can be used for 3 to 5 years.
• External hard drives are portable and can take everywhere.
• External hard drives are separate from your computer. Computer issues like system crash won’t threaten the files from your phone if you back up them to the external hard drive.

So, external hard drives are the top ideal device to hold files from your phone.
