If you see inaccuracies in our content, please report the mistake via this form. If we have made an error or published misleading information, we will correct or clarify the article. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. ZDNET's editorial team writes on behalf of you, our reader. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers. Neither ZDNET nor the author are compensated for these independent reviews.

This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Generally you want a drive that is at least twice as large as the amount of data you are. When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. Time Machine works great with external USB or Firewire hard drives. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites.

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping.
