What should I check before buying an external SSD for my Mac?

\n

Short answer: Check the connection matches your Mac's ports and comes with a good cable, enough capacity with room to grow, sustained (not just headline) speed, how it handles heat, warranty and brand, and bus power for laptops.

\n

Match the drive to your Mac and how you'll use it:

\n
  • Connection — USB-C or Thunderbolt that your Mac's ports support at full speed, with a good cable included.
  • Capacity — enough for what you'll move now plus room to grow; drives slow down when nearly full.
  • Sustained speed — reviews of large-file copies tell you more than the headline figure.
  • Heat — metal cases that shed heat cope better with long copies.
  • Warranty and brand — a reputable maker and seller.
  • Power — bus-powered for laptops, so it works from the cable alone.
\n

For Storage Studio, an SSD is recommended for anything you'll run or open daily — see what kind of drive to use and how big it should be.
