Frequently Asked Questions

How fast is the SanDisk 1TB Extreme Portable SSD?

SanDisk rates it at up to 1050MB/s read and 1000MB/s write based on internal testing. Real speeds depend on your host device and cable, and 1MB is counted as 1,000,000 bytes.

Is this SSD waterproof and drop-proof?

It carries an IP65 rating for water and dust resistance and is qualified for drops of up to 3 meters. That is an upgrade from the earlier IP55 and 2-meter ratings on prior versions.

What port does it use, and will it work with my laptop?

It connects over USB-C on a USB 3.2 Gen 2 interface. Any USB-C host works, though older or slower ports will cap throughput below the 1050MB/s figure. Check the listing for included cable details.

Can I password protect the files on this drive?

Yes. The drive includes password protection backed by 256-bit AES hardware encryption, so contents stay locked without the password. The SanDisk Memory Zone app also handles file management and freeing up space.

Why does the listing say Old Model, and is it still worth buying?

It refers to an earlier revision of the Extreme Portable line with updated firmware and macOS Monterey support. It holds a 4.6 out of 5 rating from more than 91,000 buyers, so the platform is well proven.
