What to check before ordering

Verify that your computer has a USB 3.0 port to reach the 150MB/s read speed. The drive measures 0.5 L x 1.7 W x 0.3 H inches, so confirm it fits alongside other ports. It weighs 0.04 pounds and requires no external power or drivers.

Sustained-load behaviour

Sequential reads run at up to 150MB/s while writes reach 625MB/s under typical workloads. The metal body helps dissipate heat during long transfers, keeping performance stable. Password protection and RescuePRO software add security and recovery options for continuous use.

Questions about this item

Does the 128GB Ultra Flair drive ship with any cables or software, or must I buy them separately?

The drive itself is the only hardware in the box; it plugs straight into a USB 3.0 port. SanDisk RescuePRO and RescuePRO Deluxe recovery software are available as downloads, so no separate purchase is needed.

The listing shows only a 128GB model — are there other capacities or versions of the Ultra Flair I should consider?

This specific part number SDCZ73-128G-A46 is the 128GB capacity; other capacities exist in the Ultra Flair range but carry different part numbers.

The box says 150MB/s read — what does that actually mean when I copy files to my laptop?

The 150MB/s figure is the maximum sequential read speed over USB 3.0; real-world transfers of large files will approach that rate, while small files or mixed workloads will be slower.
