In the following paragraphs, we explain what each criterion means.

Most external SSDs have a capacity of between 500 GB and 2 TB.

If you're deciding between two sizes, go for the one with the higher capacity. This gives you the option of backing up more data at a later date.

Read and write speed

Most SSDs have read and write speeds of 390 Mb/s and 550 Mb/s respectively.

The advantage here is definitely the faster working and saving of data. Notebooks and computers with built-in SSDs start up much faster.

The same observations apply to external SSD hard drives.


The enclosure not only has an optical meaning, but also says a lot about the security of your data. You can find external SSD hard drives with a metal housing or a plastic housing.

In the event of a fall, the hard drive should be protected so that no data is lost. Ideally, your hard disk should have a rubber casing to cushion the physical impact on the hard disk.


In contrast to previous storage media with a high capacity, an external SSD is space-saving. With a maximum size of 15 cm x 12 cm x 8 cm, it can be transported easily and carefree.


Connection is possible via the classic USB port. However, some external SSD hard drives offer the option of wireless connection, which means a WLAN connection is sufficient to save the data on your hard drive or to ensure an automatic upload to Dropbox.

Network storage

By connecting to a WLAN router, you can access the data on your hard drive through your smartphone. This means that you can download images from your hard drive to your smartphone at any time.

Special features

Have you always wanted to record films on TV to watch them again later? An external SSD hard drive can help you with this, because it can take over the function of a video recorder on your Smart TV.
