SanDisk Ultra 16GB USB 3.0 Flash Drive

The SanDisk Ultra SDCZ48-016G-A46 is a 16 GB USB 3.0 flash drive built for everyday file transport. It delivers read speeds up to 80 MB/s so documents, photos and videos move quickly between devices. The compact sliding design protects the connector without a separate cap. SanDisk SecureAccess software is included for password-protected file encryption.

Users needing simple portable storage up to 16 GB

This drive suits students and office workers who carry presentations, spreadsheets or media libraries between computers. The USB 3.0 interface works with USB 2.0 ports at reduced speed. Buyers who need larger capacities or sustained write performance for operating-system boot media should consider other options. The five-year limited warranty covers manufacturing defects.

Maximum read speed of 80 MB/s

The headline specification is the 80 MB/s maximum read speed, which determines how fast you can open or copy files from the drive. Write speeds are lower and vary with file type and host controller. If your workflow depends on rapid sequential writes, verify that the actual write performance meets your requirements before purchase.

Questions about this item

What real-world read speed does the USB 3.0 interface cap at for this drive?

The USB 3.0 interface on this SanDisk Ultra delivers up to 80 MB/s maximum read speed in practice.

Will the 56.8 mm x 21.3 mm x 10.8 mm body fit side-by-side with other ports on a crowded laptop?

At 2.24 inches long and 0.84 inches wide, the slim profile leaves room for adjacent USB sockets on most laptops.

How do I install the included SanDisk SecureAccess software, and what step do people miss?

Plug the drive in, open the SanDiskSecureAccess_V3_win.exe file on the drive, create a vault password, then drag files into the vault window — skipping the password step leaves files unprotected.
