The different types of storage systems in the market vary by what type of interface the storage device may have. The following summarizes the different types of storage devices there are out in there in the market.
Portable Storage Devices
These are usually pocket drives that you can carry with you that are meant to be used with laptops. These usually come with either a Firewire or USB 2.0 interface. Sometimes they also come in combination interfaces. Most of these types of drives are usually bus-powered (meaning they draw power from your computer and don't require an external power supply). Most modern mini-drives are made this way these days. They are also small enough that they can fit in your shirt pocket (or at least theoretically). Most pocket drives usually range around the 320 to 640GB storage although they are getting large with the advent of technology.
Desktop Storage Devices
These storage drives can have a mutlitude of interfaces: eSATA,Firewire or USB or all three. These drives usually can be placed near a desktop computer without having to worry about interference and usually require external power. These drives are usually designed for massive amounts of storage as these days, they tend to start around 500GB and up. In fact they can range up to 3TB and up as they are designed to store large amounts of data.
Network Storage Devices
These drives are usually LAN based, meaning they are equipped with an Ethernet Ports. These drives usually won't have the same initial storage capacity as Desktop Versions, but may come in different versions where you can add multiple drives to create either Consolidated Storage Drives or as RAID Drives. These types of drives are great for sharing data over a network as any computer on a network can use these types of drives.
