With a 35% MTBF improvement
over standard desktop drives, the
WD Red drive is designed and
manufactured to be a more reliable

Applications

WD Red NAS hard drives are recommended for use in home and small office 1-5 bay NAS systems. For systems that use more than 5 bays or are rack mount
solutions, please consider WD enterprise hard drives.*
*WD hard drives are designed and tested for use in specific applications and environments. This ensures that your hard drive is compatible with and functions properly in your application. Our
hard drives are warranted against defects in materials and workmanship in the system for which they were designed. Use in systems other than for what the hard drive was designed could
result in compatibility problems that affect proper function, unrelated to material and/or workmanship defects. For best results, be sure to select the appropriate product for your application
by consulting our product spec sheets on our website at www.wd.com or by calling our customer support line where we would be happy to help you through the selection process.
