As the world's first enterprise class 10TB HDD, HGST launches Ultrastar Archive Ha10 to address the emerging Active Archive segment in the capacity enterprise space. Optimized for highest capacity at the lowest TCO, the Ha10 provides unprecedented capacity leadership by harnessing two core complementary technologies— HelioSeal and host managed shingled magnetic recording (SMR) to deliver uncompromising quality and reliable performance. Ultrastar Archive drives are designed specifically for Active Archive environments and will not work as drop in replacements for traditional capacity enterprise drives. To take advantage of the capacity and predictable performance of host managed SMR benefits, customers will need to modify their end application or kernel space to interface with new command sets, and data streams must be sequentialized for writing to the drive. The investments made in software changes will also help enable future host based SMR solutions, and provide a path to future recording technologies. At the core of its design, the Ha10 leverages the proven and mature HelioSeal platform to deliver an unmatched Watt/TB power footprint, ideal for ultra dense scale out storage systems, with uncompromising product reliability, necessary for private and public cloud enterprise applications. By combining host managed SMR with HelioSeal, Ha10 offers a 25 percent increase in capacity compared to drives using perpendicular magnetic recording (PMR) technology, while delivering a highly predictable, highly reliable performance unseen in any other SMR implementation. Because host managed SMR enforces the sequentiality of all incoming data and also provides control at the host level, customers can now intelligently tier their storage from hot-to-cold while maintaining a consistent performance profile regardless of packet size, number of data streams, or workload. Active archive applications need maximum capacity, low Dollar/TB, and high data quality with consistent, reliable performance as a secondary requirement. Ha10 meets all these needs and also delivers enterprise class characteristics for bit error rate, drive speed and rotational vibration specifications.
