Overview

The SanDisk Ultra Flair SDCZ73 is a USB 3.0 flash drive rated for sequential read speeds up to 150MB/s — roughly 15 times the throughput ceiling of USB 2.0. In practical terms, that means transferring a 4GB file in under 30 seconds on a USB 3.0 port. Each drive in this two-pack provides 128GB of NAND flash storage in a capless metal enclosure that measures just a few centimeters long. The included SecureAccess software enables 128-bit AES encryption for password-protecting sensitive files directly on the drive, without requiring additional software purchases.

This two-pack configuration is well-suited for users who need multiple portable drives — one for active project files and another for backup, or separate drives for work and personal data. The all-metal body is durable enough for daily pocket or keychain carry, though the capless design means the connector stays exposed. These drives are best used for file transport, quick backups, and bootable media where read speed matters most. Users who need fast write performance for tasks like continuous video capture should look at higher-tier drives with faster NAND controllers.

Frequently Asked Questions

The Ultra Flair is rated at up to 150MB/s sequential read on USB 3.0. Write speeds are significantly lower, typically 30-40MB/s. You'll hit peak read speeds on large contiguous files; small file transfers will be slower due to NAND overhead.
Yes, the Ultra Flair works in any USB-A port. On USB 2.0 you'll be limited to roughly 30MB/s read, which is the ceiling of that bus standard. No drivers or adapters needed.
SanDisk includes SecureAccess software preloaded on the drive. It creates a 128-bit AES encrypted vault for selected files. The software runs on Windows and macOS. Note that it protects a folder within the drive, not the entire volume.
The Ultra Flair supports booting on most BIOS and UEFI systems. The metal casing helps with thermal management during sustained reads, which is useful during OS installation. Format as GPT with a FAT32 EFI partition for broadest compatibility.
