Portable SSDs and Flash Drives: Keep Your Files Safe

A laptop can fail, phones get stolen, and a single missing file can ruin your week. Portable storage is an inexpensive way to protect what matters.

Flash drives

Flash drives are small and useful for moving documents, school assignments and printing. Our SanDisk range includes Cruzer Blade, Cruzer Fit, Cruzer Glide, Ultra Flair, Ultra Luxe and a USB Type-C drive.

Cruzer models are basic and affordable. Ultra Flair and Ultra Luxe tend to be faster for bigger files. The Type-C drive connects directly to USB-C laptops, tablets and phones.

Flash drives can be slow for large transfers, and they are not designed for use as primary storage.

Portable SSDs

Portable SSDs are much faster and more durable. The SanDisk Portable SSD (E-30), Extreme Portable SSD V2 and Extreme PRO Portable SSD V2 are designed for different levels of performance. Extreme-class drives are popular with photographers and video creators.

Check that your computer has a fast enough port to use the drive's full speed.

How much capacity?

• Documents and school work: 64GB to 128GB flash drive.
• Photos and general backup: 500GB to 1TB.
• Video creators: 2TB and up.

The 3-2-1 backup rule

Keep 3 copies of important data, on 2 different types of storage, with 1 copy stored somewhere else, such as the cloud or another location.

Even a simple version is better than nothing. Keep your thesis, business records and family photos in more than one place.

Avoid fake drives

Fake flash drives may claim large capacities but silently lose files once a low limit is reached. Be suspicious of implausibly cheap high-capacity drives. Buy from a reliable seller, and test by copying and reopening files.

Protect your data

Use encryption if a drive stores sensitive information. Windows BitLocker and macOS FileVault-style encrypted disk formats can help. Remember your password, because data may be unrecoverable without it.

Scan shared flash drives for malware before opening files, especially in cyber cafés or at school.

Safe removal

Use the eject option before unplugging. Removing a drive during a transfer can corrupt files.
