Frequently Asked Questions

Why does my SSK 2TB SSD show only about 1863GB on Windows?

Windows counts 1GB as 1024MB, while SSD makers count 1GB as 1000MB. Because of that, the 2TB drive appears as roughly 1863GB on Windows, about 7% to 10% lower. macOS typically shows the full 2TB. No storage is missing.

Will I actually get 2000MB/s transfer speeds?

The 2000MB/s rating needs a USB 3.2 Gen2x2 (20Gbps) port and the included USB-C cable. With the included USB-A cable, the link is limited to 10Gbps. Speeds also depend on the SLC cache, which uses 25% of the drive's currently available capacity.

Does this SSD work with iPhone 15 and MacBook?

Yes. SSK lists iPhone 15, MacBook and MacBook Pro, laptops and OTG-capable phones as compatible. It connects over USB-C, and an included USB-A cable covers older computers.

Which cables come with the SSK portable SSD?

The drive ships with two cables: a 20Gbps USB-C cable for USB 3.2 Gen2x2 hosts and a 10Gbps USB-A cable for computers with standard USB-A ports.

How can I monitor the drive's health and keep it running fast?

The drive supports S.M.A.R.T. monitoring, so you can check its health with a compatible disk utility. It also supports TRIM, which helps keep write speeds consistent and extends drive life. For warranty coverage, check the current product listing.
