SanDisk Flash Drives

Reliable USB Flash Storage from 8 GB to 2 TB

SanDisk USB flash drives deliver dependable portable storage from basic USB 2.0 thumb drives to high-speed USB 3.2 Gen 1 models, with capacities from 8 GB to 2 TB across the Ultra, Extreme, Cruzer, Dual Drive, and iXpand product families. The lineup sits within the broader Western Digital family of hard drives, SSDs, and memory cards, and you can compare across all portable storage in the complete storage category.

SanDisk Flash Drives for Every Use Case

• IT deployments and bootable installers — SanDisk Ultra Fit and Ultra Flair drives in 8 GB to 32 GB provide fast, reliable media for Windows, Linux, and firmware deployment across device fleets
• Professional file transfers — the Extreme Go pushes read speeds up to 400 MB/s and the Extreme PRO reaches 420 MB/s reads and 380 MB/s writes, rivaling some portable SSDs for moving large project files between workstations
• Cross-device compatibility — Dual Drive models with both USB-C and USB-A connectors transfer files between modern laptops, tablets, and phones without adapters or dongles
• iPhone and iPad backup — iXpand drives with Lightning or USB-C connectors back up photos and videos directly from iOS devices, freeing up phone storage without cloud subscriptions
• Bulk deployments and giveaways — Cruzer Blade and Cruzer Glide USB 2.0 drives offer the lowest cost per unit for bulk orders where basic file storage is the only requirement

Choosing the Right SanDisk Flash Drive

SanDisk organizes its flash drive lineup by speed tier and connectivity. The Ultra family covers everyday USB 3.0 use from 100 to 150 MB/s reads. The Extreme line targets professionals who move large files regularly at up to 420 MB/s. The Cruzer series offers budget USB 2.0 options for small documents and firmware. The Dual Drive and iXpand lines add multi-connector flexibility for cross-device workflows.

Speed Tiers

USB 2.0 drives like the Cruzer Blade cap out around 15 to 20 MB/s, fine for small documents and firmware files but slow for multi-gigabyte transfers. USB 3.0 and 3.1 drives in the Ultra family jump to 100 to 150 MB/s reads. The Extreme Go and Extreme PRO push into 400+ MB/s territory, making them practical alternatives to portable SSDs for transferring large photo sets, video projects, and database backups.

USB-C vs. USB-A Connectivity

If you work across devices with different port types, a Dual Drive eliminates the need for adapters. The USB-C end connects to modern laptops, tablets, and phones, while the USB-A end works with older desktops and docking stations. For iPhone users, the iXpand line provides direct Lightning or USB-C connectivity alongside a standard USB-A plug.
