What customers say about "Key Specs"
Seagate Fast SSD Portable External Solid State Drive for PC and Mac
  • I haven't owned the SSD for long, but so far it's been great. Surprisingly fast, small footprint and well worth the price.
  • I'm not easily impressed but this SSD drive copies files to my laptop at 460 Mb/s through a Thunderbolt 3 port.
  • The Seagate SSD is a bit faster than its WD counterpart in giving you alphabetical listings by title , artist, etc, and it doesn't heat up like the WD.
  • This is the first SSD external drive and it is great. Small, lite, and opens and runs files, apps, so much faster than my HDD.
