Manufacturer description
The SSK Portable SSD 1TB is a pocket-sized external solid state drive built for people who move large files fast. Over the USB 3.2 Gen2 10Gbps interface it reads up to 1050MB/s and writes up to 1000MB/s, so a folder of 4K footage lands in the time a spinning drive would still be spinning up. SSK ships both USB-C and USB-A cables in the box, which means the same drive plugs into a MacBook, a Windows desktop, an Android tablet, or an iPhone 15/16/17 Pro without an adapter hunt. That iPhone compatibility is the standout: at under 2.4 watts draw, it records 4K60Hz ProRes HDR straight off the…

Frequently Asked Questions
Why does my 1TB SSK drive only show 931GB?
That is the binary versus decimal calculation difference, not missing storage. Windows reports about 931GB while macOS shows the full 1TB. The physical capacity is identical either way.
Can I record ProRes video straight to this from an iPhone?
Yes. SSK rates it for 4K60Hz ProRes HDR capture on iPhone 15, 16, and 17 Pro models, drawing under 2.4 watts so it runs off the phone without a powered hub.
Do I need to buy a separate cable for my older laptop?
No. Both a USB-C and a USB-A cable are included, each rated for USB 3.2 Gen2, so it connects to newer and older machines out of the box.
Will the speed hold up during a very large file transfer?
Sustained 10Gbps applies to transfers that fit inside the SLC cache, which is 25% of currently available capacity. Transfers larger than that cache window will slow down.
Does it get hot enough to worry about?
SSK measures a case peak of 105.58F. The 2mm aluminum alloy shell acts as the heatsink, and there is no internal fan, so it stays silent.
