The GoFlex for Mac ultra-portable drive makes it easy to store, transport and back up all of your fles. Bundled with the most popular interfaces and up to 1.5TB of storage, the drive is HFS+ formatted which makes it fully compatible with Time Machine software. Use the included plug-and-play FireWire 800 or USB 2.0 interface or upgrade to USB 3.0 or powered eSATA by pairing the drive with the appropriate GoFlex upgrade cables. Take advantage of the drive's versatile design to upgrade to the fastest interfaces available. Pair the drive with the additional GoFlex storage system products and access your content on your TV, over your network or on-the-go. Install the downloadable HFS+ driver on the PC to use the drive interchangeably between the two without having to format. This is the perfect solution for primarily Mac computer users who still regularly utilize a PC. The drive's durable soft-touch metallic finish not only helps resist fingerprints, it also blends in perfectly with Apple products.
