Super Slim, Super Lightweight The brand new NH92 Portable Hard Disk Drive is distinguished by its ultrathin body, which measures only 12 mm thick and fits perfectly in any handbag. And at just 152g, the NH92 is hardly noticeable – the perfect companion to take along, anytime and wherever you go. A Feat of Exquisite Engineering The Nobility Series NH92 impresses with its slim design, its eye-catching sleek and durable aluminum case and smooth texture.
