Pros and cons

Pros

  • The 128GB capacity suits carrying a sizeable collection of files on one small drive.
  • The swivel cover avoids a separate cap, while the key-ring attachment can make the drive easier to keep with keys or a lanyard.
  • The stated read and write rates give buyers separate speed claims to compare with their transfer needs.

Cons

  • The stated maximum write speed is lower than the stated read speed, which may make large file transfers less convenient than reading files.
  • The listed connector is USB Type-A, so devices without a compatible port may need a suitable adapter.

What to know before buying

Listing details to confirm

The title claims speeds up to 80MB/s, while the details give the read rate as 80 Megabytes Per Second and write rate as 25 MB per second. Customer feedback on speed and reliability is mixed, including reports of very slow transfers and a drive locking after one save. The speeds are listing claims, not independent measurements, so this is a better fit for routine file carrying than for buyers who need predictable transfer performance.

Who is it for?

A good fit for

  • People wanting a compact 128GB drive for documents, photos, music or other files.
  • Buyers with a USB Type-A port who want a swivel-cover design and key-ring attachment.
  • Everyday file storage where the stated speed claims are adequate and consistent performance is not a critical requirement.

Less suited to

  • Buyers seeking USB-C connectivity without an adapter.
  • People who need assured fast transfers or dependable performance for critical files, given mixed customer feedback on speed and reliability.
