Other World Computing, or OWC, a tech company that specializes in making high-performance storage, memory, connectivity, software, and accessories, has just introduced a new SSD storage device, the OWC Express 1M2 80G Portable SSD, which is available in several capacities (1TB, 2TB, 4TB, and 8TB ). According to the specs, it’s very lightweight (9.9 ounces), compact (roughly the size of a stack of 3x5-inch index cards), easy to set up and use, and compatible with many platforms (PC, Mac, iPad Pros, Chromebooks, and Surface devices).

That makes it ideal for all types of photographers, artists, and creators, particularly if you’re traveling or on the go and need a reliable, fanless SSD: Pro photographers and videographers will be impressed with its ultra-fast, reliable storage for large RAW files and 4K/8K video editing. Content creators who work in the field (journalists, filmmakers, and audio engineers) will like that it’s a high-capacity, portable, bus-powered storage. Mobile performance enthusiasts will find the SSD invaluable, with its Thunderbolt 5/USB4 compatibility and its peak speeds above 6000MB/s. Additionally, the company says it has a solid aluminum, heatsink-like finned design that ensures silent, throttle-free heat dissipation to support real-world peak speeds of over 6000MB/s. (The OWC Express 1M2 80G is available as a 0GB enclosure.)
