Frequently Asked Questions
Does the SSK 2TB portable SSD work with iPhone 15 and iPhone 15 Pro?
Yes. SSK lists iPhone 15 and 15 Pro compatibility. Use the included USB-C cable to connect the drive straight to the phone's USB-C port for file transfers.
Why does my 2TB SSK SSD only show about 1863GB in Windows?
Windows counts 1GB as 1024MB, while drive makers count 1GB as 1000MB. That makes the displayed size 7-10% smaller, so 2TB shows as about 1863GB in Windows. macOS usually shows the full 2TB.
Can I plug it into a computer that only has USB-A ports?
Yes. The drive comes with a USB-C cable and a USB-A adapter, so it works with older USB-A computers as well as newer USB-C laptops, tablets and phones.
Will it slow down when copying large video files?
SSK allocates 25% of the drive's currently available capacity as high-speed SLC cache to keep large transfers steady at up to 550MB/s. The cache shrinks as the drive fills, and actual speed also depends on your host device, OS and application.
How can I check the health of this external SSD?
The drive supports S.M.A.R.T. monitoring, so standard disk-health utilities can read its status. It also supports TRIM, which helps keep write speeds consistent over time. The LED light shows when the drive is active.
