SanDisk Ultra USB 3.0 64 GB 100 MB/s SDCZ48-064G-U46

What it is and who it suits

The SanDisk Ultra USB 3.0 flash drive provides 64 GB of portable storage in a compact black casing. It is aimed at students and office workers who need to move documents, photos or videos between computers quickly. The USB 3.0 interface delivers up to 100 MB/s read speeds for everyday file transfers.

Check your setup first

Verify that your computer has a USB 3.0 Type-A port to achieve the quoted 100 MB/s performance; the drive will fall back to USB 2.0 speeds on older ports. Ensure your operating system supports exFAT or NTFS if you plan to store individual files larger than 4 GB. No drivers or external power are required for operation.

Build quality and daily use

The drive uses a sliding retractable connector that protects the USB plug when not in use, removing the need for a separate cap that can be lost. Its lightweight plastic body resists minor knocks and fits easily on a keyring or in a pocket. The black finish hides fingerprints and scratches during regular handling.
