Kingston broke the $4 billion sales barrier in 2007, with the vendor citing strong performance in its Flash memory business as the reason behind growth.
The division's performance helped to push the company's revenues up $800 million on 2006's figures.
Speaking about the company's performance, Kingston's co-founder John Tu said: "Reaching $4.5 billion is a remarkable achievement in the history of our company. When David Sun and I started the company in 1987, we never dreamed that this level of success was possible.
"We owe it all to the hard work of our employees and their dedicated support of Kingston’s industry partners, vendors and ultimately, our customers."
"Kingston stands committed to building a high-quality product backed by outstanding customer service,” added Sun.
"This was our foundation when we started 20 years ago and it remains our hallmark today. This dedication and conviction have allowed Kingston to endure and grow, even in today’s tough market environment."
