Seagate Shows Off Capacious 4TB Hard Drive for NAS Boxes

Seagate on Tuesday unveiled a new line of drives custom-built for always-on network attached storage (NAS) systems. Multiple capacities are available, including a 4TB model that's currently the industry's highest capacity available from a single NAS HDD. The new drives are intended for NAS boxes with up to five drive bays.

"Today about 50 percent of NAS arrays are sold diskless meaning that customers are challenged with identifying and installing the right storage for their system. By developing a drive like NAS HDD, we’ve taken the guesswork out of it and made it easy for customers to identify the right drive for their system," said Scott Horn, Seagate vice president of marketing. "By collaborating closely with a variety of partners who specialize in NAS systems, we’re making what was a confusing effort into a plug-and-play one."

In a five-bay NAS, home users and small-to-midsize businesses (SMBs) can enjoy up to 20TB of storage by shoving a handful of 4TB drives into the system. To put that into perspective, each 4TB drive is capable of storing 819,000 photos, 1 million songs, or almost 500 hours of high-definition video, Seagate says.

The NAS drives are equipped with 64MB of cache and a SATA 6Gbps interface. Seagate rates the maximum sustained transfer rate at 159MB/s on the 2TB model and 180MB/s on both the 3TB and 4TB models. To keep all that data safe, the drives feature improved vibration tolerance and error recovery controls.
