Are you finding a limit of space in your hard drive on your home or office computer. Maybe you want to share files between home and office but don’t want to carry a work computer home with you everyday. Some people need a simple way to back up their files from their computer. There are a million different reasons to need some type of external memory and knowing which type to purchase means knowing what you need to do with it.
If you are looking for a way to back up your own computer or share files throughout your home network then a network attached hard-drive may be for you. These large capacity devices will connect to your home or office network allowing any computer in the network to access the drive.
There are also hard drives that connect to your computer through USB connections. These devices can range in size form mega-bites to hundreds of gigabytes. These can be very portable and very low cost. This type of device in the 1 gigabyte to 2 gigabyte size can easily be shared and passed between people.
Another type of external memory is small, often used in cameras, SD and other small memory chips. These memory cards can be as large as 32 gigabytes and are very small. These chips are more expensive but as the memory space on them grows they become more possible to store large amounts of data. Many computers now have drives that these memory chips can be plugged and played, very easily.
Another possible option, although not a device you carry around is to back your information on an internet based service. All of these options are available and it is up to you based on your budget and need for mobility.
