    SSD drives are faster and have no moving parts, however are more expensive for the same size as standard drives (magnetic rotating platter).

    That being said,

    External USB drives are typically not of the SSD type due to the higher costs and smaller sizes that are availible.

    Common SSD sizes are 128 and 256 Gigabyte. They are often used internally in ultralight laptops or as a boot drive in a high performance system due to their faster access times.

    External drives usually are mounted in a USB case, and can be in 3.5 (standard) or 2.5" (laptop) sizes. Most sold today are 1 TB (1000 GB) or larger and are relatively inexpensive.

    You can buy a 2 Terabyte external drive for around $100 http://www.amazon.com/gp/product/B00CGUMS48/ref=as...

    Contrast that with a 256 MB SSD drive which runs around $170. http://www.amazon.com/gp/product/B008M9U3CG/ref=as...

    Good Luck.

    They *can* be the same thing.

    SSD means Solid State Drive. Older drives used moving parts/pieces to read/write data akin to an old school vinyl record and record player. Solid State drives have no moving parts and are based off flash memory (think USB Thumb Drive type of storage).

    An external drive is nothing more than a 2.5" (or 1.8") laptop hard drive put into an enclosure that turns it into a USB external drive instead of being an internal hard drive. It COULD be a Solid State Drive but it COULD also be the "old school" platter disks. Look at the specifications of the device you're looking at. It should specify the type of disk.

    SSD is Solid state Drive, means instead of the regular platter inside the HDD, ssd's will have flash memory inside. means there's no moving parts inside.

    external hdd's are the hdd's which are located outside the computer connected thru USB or another connectivity port., this external hdd can have a regular hdd or ssd inside

    Yes. SSD stands for:

    Sempi Solutrodon Deimante... that's Latin for memory outside device... or external harddrive. The French thought that External Hard Drive sounded too American and wanted a more European name, hence the SSD.
