Frequently Asked Questions
Will this SSK drive work with an older iPhone that has a Lightning port?
No. The drive only supports USB-A and USB-C connections and is explicitly incompatible with Lightning ports, though it does list compatibility with USB-C iPhones in the 15, 16, and 17 lines.
Do I need to install any software before using the SSK dual drive?
No software is required. The drive is plug-and-play and ships preformatted as exFAT, so it reads and writes on Windows, macOS, Linux, and Android right out of the package.
How fast is the SSK 256GB drive compared to a regular flash drive?
SSK rates it at up to 550MB/s read and 500MB/s write, which it describes as roughly ten times faster than a traditional USB 3.0 flash drive, though actual speed depends on your host device and port.
Can I use this drive with both my Type-C phone and my older USB-A laptop?
Yes. That is the core design. It has a USB-C connector and a USB-A 3.2 connector on one body, so it moves files between modern phones and USB-A computers without needing an adapter.
Is the 256GB SSK drive durable enough for daily carry?
It uses a high-grade zinc alloy shell rated for shock resistance and heat dissipation, plus a double-head protective cover that shields both connectors while the drive is in a bag or pocket.
Will the drive still work if I plug it into an older USB 3.0 or 2.0 port?
Yes, it is backward-compatible with USB 3.0 and 2.0 ports, but those slower interfaces will cap transfer speeds below the drive's rated 550MB/s ceiling.
