Capacity and interface

The SanDisk Ultra Flair is a 256GB USB 3.0 flash drive with a silver metal casing. It suits anyone who needs portable, high-capacity storage for documents, media or backups that must move between Windows and macOS computers. The drive includes SanDisk SecureAccess software with 128-bit AES encryption and password protection for private files.

Sustained transfer behaviour

Read and write speeds are rated at up to 150MB/s for this capacity, so large files such as full-length movies can be moved in roughly 30 seconds under ideal conditions. Performance will vary with the host controller, file sizes and system load; the metal body helps dissipate heat during extended write sessions but the drive has no active cooling. Operating temperature range is 32 to 95 degrees F.

Host compatibility checklist

Verify that the target computer provides a USB 3.0 Type-A port to reach the quoted speeds; the drive will fall back to USB 2.0 on older ports. Confirm that the operating system is a supported version of Windows or macOS for the included SecureAccess software. No external power or driver installation is required. Buyers who need hardware encryption, USB Type-C connectivity or ruggedised water resistance should consider other models.

商品問答

Does the metal casing get hot when the Ultra Flair runs at 150MB/s all day?

The drive operates between 32 and 95 °F and has no moving parts, so it stays cool during sustained transfers.

What must my computer already have to reach the 150MB/s read speed on this 256GB drive?

A USB 3.0 port is required; USB 2.0 ports will fall back to slower speeds.

Will the SanDisk SecureAccess software and 128-bit AES encryption work on my older Windows 7 laptop?

The software supports Windows and macOS; check the SanDisk site for the minimum OS version needed.
