Real-world performance
Read speed: ~120–150 MB/s
Write speed: Usually 20–60 MB/s, depending on the capacity and file size.
During long transfers of large files, the drive can become quite warm, and write speeds may drop due to thermal throttling.
Pros
Fast file copying for documents, photos, and movies.
Compact and sturdy metal design.
Good value for everyday backups and portable storage.
Cons
Gets hot during extended use.
Sustained write speeds are much lower than read speeds, so it’s not ideal for frequent large file transfers or running operating systems from the drive.

If you’re planning to buy one, tell me the capacity you’re considering (32 GB, 64 GB, 128 GB, 256 GB, etc.), and I can advise whether it’s a good choice for your specific use case.
