sandisk ultra 256gb usb drive 3.0 flash drive

Key features

• USB 3.0 interface (backward compatible with USB 2.0)
• Read speeds up to 150 MB/s (manufacturer rating)
• Durable metal casing
• Available in 16 GB to 1 TB capacities
• Includes password protection with SanDisk SecureAccess software

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.
