HGST Ultrastar SN100 goes NVMe


Storage vendor HGST has delivered on its promise of NVMe compliance for the Ultrastar SN100 PCIe SSDs.

Western Digital subsidiary HGST announced its Ultrastar SN100 PCIe SSDs last September.

At the time, the company said it would be releasing NVMe-compatible extensions that will allow improved interaction between software and SSDs, giving up to twice the performance and endurance.

That has come to pass, and HGST is now shipping NVMe compliant Ultrastar SN100 series PCIe SSDs, initially in the half-height, half-length format (1.6TB, 3.2TB), with the hot-swappable 2.5in small form factor models (800GB, 1.6TB, 3,2TB) to follow in May.

The drives are said to perform at up to 310,000 random mixed read/write IOPS (70/30, 4KB), up to 160,000 random write IOPS (4KB), and up to 743,000 random read IOPS (4KB). Sequential read and write throughput is 3,000 MBps and 1,600 MBps.

This is said to translate to MySQL performance improvements of up to 60%.

The Ultrastar SN100 series works with the standard NVMe drivers for server operating systems, and use a standard interface (PCIe Gen 3 x4) for compatibility with a broad range of servers. This makes them as easy to deploy as traditional storage devices, HGST said.

"With our new Ultrastar SN100 Series, HGST is helping today's data center professionals meet one of their most important and difficult storage challenges: deliver extremely high application performance in a cost-effective manner," said HGST flash platforms group senior vice president and general manager Mike Gustafson.

"By standardising the deployment process with NVMe, IT organisations can now realise unprecedented gains in terms of application performance, server consolidation, and simplified setup and management in Linux, Windows and virtualised environments.

"This milestone is important as it allows customers to easily implement high-capacity PCIe SSDs at scale in a variety of data centre environments."
