Enterprise SSD for tier‑0 storage

The HGST Ultrastar SSD1600MR HUSMR1616ASS205 is a 2.5 inch enterprise SSD with 1.6TB capacity and a SAS 12Gb/s interface. It uses MLC NAND and targets ultra‑high performance tier‑0 read endurance workloads such as OLTP, video production, cloud computing and high performance computing environments.

Sustained performance and efficiency

Random read reaches up to 130,000 IOPS and random write up to 30,000 IOPS at 4KB block size. Active power draw is 2.2W, delivering best IOPS per watt for reduced total cost of ownership. Advanced power loss data management protects in‑flight data and the drive operates from 0°C to 60°C with shock resistance of 1000G at 0.5ms and 500G at 2ms.

Compatibility and form factor check

Verify that your server or storage array accepts a 2.5 inch SAS drive with a 15mm z‑height and supports the SAS 12Gb/s protocol. The unit measures 70.1mm wide by 100.6mm deep and weighs 187g. Self‑encrypting variants conform to TCG Enterprise specification, so confirm whether your infrastructure requires or supports hardware encryption.
