Buying Guide
Speed That Matches Your Workflow
Both SSK drives boast read speeds up to 1050 MB/s and write speeds up to 1000 MB/s, thanks to USB 3.2 Gen 2. This means you can transfer large files in seconds, edit 4K video directly from the drive, and load games without waiting. The SLC caching technology ensures consistent performance even during heavy transfers, so you won’t hit a slowdown wall.
Capacity Choices: 250GB vs. 500GB
The 250GB version is ideal for documents, a few games, and daily backups. The 500GB version gives you more room for high-resolution photos, video projects, and a growing library. Both handle the same blazing speeds, so the choice comes down to your storage needs. For everyday portability, the smaller capacity is lighter on the wallet; for heavier workloads, the larger drive is a smart investment.
Portability and Build Quality
At just 36.6 grams and barely larger than a credit card, these SSDs slip into any pocket or bag. The 2mm aluminum alloy case dissipates heat efficiently, keeping the drive cool even during extended use. The included USB-C and USB-A cables make it compatible with modern laptops, smartphones, and even your iPhone for 4K ProRes video capture.
