Portability: All of our external SSD recommendations are bus powered, which means they draw electricity from your computer’s USB port. Using a USB-C cable will substantially improve your external SSD’s read and write speeds. Your actual speeds will vary based on how many files you’re trying to transfer at once, or the size of the files you’re transferring.Ĭonnector: You can connect any of our external SSD picks to your computer with a USB-A cable, but most of them are also compatible with USB-C. We chose drives that support the USB 3.0 standard, which has a maximum data transfer speed of 640mbps, USB 3.1 standard, which has a maximum data transfer speed of 1,280mbps, and USB 3.2 standard, which has a maximum data transfer speed of 2,000mbps.
Read and write speed: The speed at which an external SSD and writes data is important to consider because it ultimately determines its performance. Our external SSD recommendations are available in multiple sizes, and run the gamut between 240GB and 2TB, so check how much data is on your computer’s drive before you make a final decision. A good rule to follow is to have one that’s twice the size of your computer’s internal hard drive or SSD, so it can store multiple versions of the same files, or different backups. Storage capacity: The amount of data an external SSD can hold is measured in GB (Gigabytes) or Terabytes (TB).
There are many factors to consider when choosing the right external SSD for you below are the most important ones, which we considered while we were researching this list. Second, an SSD has no moving parts, which means its far less likely to get damaged, especially when it’s moving around in a backpack or piece of luggage. This allows them to read and write data a lot faster than external hard drives can. First, they store your data on memory chips (like your phone or tablet), not a large, spinning disk. External SSDs differ from traditional external hard drives in two significant ways. That’s why we recommend keeping a local backup of your entire computer (or at least the most important files) on an external SSD. Your information can also be compromised if the cloud service you subscribe to gets hacked.
Accessing your files (or uploading new ones) requires an internet connection, and storing a lot of data requires you to pay a monthly subscription.
