Overview

The SSK Portable SSD makes its case on portability and speed. At 36.6 grams with a footprint of 2.6 by 1.5 by 0.5 inches, it is small enough to disappear into a jacket pocket, yet it carries a full terabyte and a 10Gbps USB 3.2 Gen2 interface rated for reads up to 1050MB/s and writes up to 1000MB/s. It suits photographers, videographers, and anyone shuttling large files between machines. A standout detail is mobile capture: with power draw under 2.4 watts, SSK says the drive can record 4K60Hz ProRes HDR video directly from a compatible iPhone.

Construction centers on a 2mm aluminum alloy case that doubles as a heat sink, with SSK listing a peak case temperature of 105.58°F. An LED signals activity, and the bundle includes both USB-C and USB-A cables for cross-platform use across computers, tablets, and phones. Behind the scenes, SLC caching sets aside roughly a quarter of available space as a fast buffer to keep large transfers smooth, while S.M.A.R.T. diagnostics and adaptive TRIM manage data blocks in the background. Buyers should note the Windows capacity readout of about 931GB, a binary-math quirk rather than a shortfall in physical storage.

Frequently Asked Questions

That is a binary calculation difference, not lost storage. Windows counts in binary while the capacity is rated in decimal, so macOS may show the full 1TB even though the physical storage is identical.
Yes. SSK states it supports 4K60Hz ProRes HDR capture from a compatible iPhone, helped by power draw under 2.4 watts that lets it run off the phone without external power.
It includes both a USB-C and a USB-A cable, both rated for USB 3.2 Gen2. That lets you connect to newer USB-C laptops and phones as well as older USB-A ports without buying anything extra.
It holds a steady 10Gbps for transfers within the SLC cache, which is about 25% of current available capacity. Copies larger than that buffer may slow once the high-speed cache is used up.
SSK lists a peak case temperature of 105.58°F and uses a 2mm aluminum alloy case for heat dissipation. The metal body is designed to spread heat and keep performance reliable during demanding transfers.
Very. It weighs just 36.6 grams and measures 2.6 by 1.5 by 0.5 inches, so it fits easily in a pocket or small bag while still holding a full terabyte of data.
