OWC Guardian: External SSD offers hardware encryption and touchscreen

The manufacturer OWC (a.k.a. Other World Computing) has introduced a rather unusual external SSD called the Guardian. This device targets users who prefer or require particularly high data security and strong encryption. More specifically, it features 256-bit AES encryption supported by a dedicated coprocessor, which is supposed to prevent slowdowns.

Because this encryption takes place at the hardware level, no software is necessary and the SSD works with different operating systems. A color touchscreen can be used to type the code or passphrase with 6 to 30 characters. Since fingerprints could compromise these codes, the layout of digits and letters is randomized each time, and both the user and administrator can define individual passwords.

The OWC Guardian SSD measures 4.76 x 2.99 x 0.63 inches and can be automatically locked after a certain period of time, and all data can be erased after a certain number of incorrect unlock attempts. Additionally, there is a read-only mode, which can be practical when connecting the gadget to unknown devices with an unverified security status. For instance, this can prevent malware from spreading to the SSD.

Moreover, the Guardian supports single and double-sided M.2 SSDs with up to 1,250 MB/s via USB 3.2 Gen 2. The smallest model has a 1TB SSD and costs $220, while the 4TB version is priced at $530. Alternatives are also available on Amazon, such as the Samsung T7 Shield.
