What this drive is and who it suits

The SSK 512 GB USB 3.2 Gen 2 portable SSD combines a USB-C connector and a USB-A 3.2 connector in one zinc-alloy body. It delivers up to 550 MB/s read and 520 MB/s write speeds for moving large files between phones, tablets, laptops, desktops, smart TVs and consoles such as PS4 and PS5. The drive arrives formatted exFAT for immediate plug-and-play use on Windows, macOS, Linux and Android devices.

Check your host ports before ordering

Full 550 MB/s read and 500 MB/s write performance requires a USB 3.2 Gen 2 port on the host device. Connecting to a USB 3.0 or USB 3.1 Gen 1 port limits transfer speed to 450 MB/s. The USB-C connector fits iPhone 15 and later models with USB-C; it will not work with Lightning-port iPhones or iPads. No driver or software installation is needed on any supported platform.

What the dual-connector design changes

Having both USB-C and USB-A on the same stick removes the need for separate adapters or cables when moving data between newer USB-C devices and legacy USB-A ports. The exFAT format means the 512 GB capacity — shown as roughly 476 GB on Windows because of 1024 MB versus 1000 MB counting — is instantly readable and writable across Windows, macOS, Linux and Android without reformatting. The metal casing adds drop and abrasion resistance while helping dissipate heat during sustained transfers.

Questions about this item

What comes with the 512 GB dual USB-C / USB-A drive and do I need any extra cables?

The drive itself has both a USB-C and a USB-A 3.2 connector built in, so it plugs directly into either port without any separate cable or adapter.

How do I decide between the listed speed figures for this 512 GB model?

The drive is rated for up to 550 MB/s read and 520 MB/s write over USB 3.2 Gen 2; if you connect it to a USB 3.0 or 3.1 Gen 1 port the speed will be limited to 450 MB/s.

What does the 550 MB/s headline figure mean when I copy files to my Windows PC?

On Windows the 512 GB drive shows about 476 GB usable space, and real-world transfers will reach the rated speeds only when the host port supports USB 3.2 Gen 2; otherwise they top out at 450 MB/s.
