Ultrastar SSD1600MM 800GB SAS drive

The HGST Ultrastar SSD1600MM HUSMM1680ASS200 is a 2.5 inch enterprise SSD with an 800GB capacity and a 12Gb/s SAS interface. It uses MLC NAND flash to deliver up to 130,000 random read IOPS and up to 10,000 random write IOPS. The drive carries a 2,000,000 hour MTBF rating and includes advanced power loss data management technology.

Suited for write-heavy tier-0 workloads

This SSD targets ultra-high performance tier-0 enterprise storage, online transaction processing, database analytics and high performance computing environments. It also fits space and power constrained servers and video pre- and post-production workflows. Buyers needing higher capacity per drive or a different interface protocol should evaluate alternative models.

12Gb/s SAS interface for host connectivity

The single specification that determines compatibility is the 12Gb/s SAS interface, which requires a matching controller or backplane in the host system. Without a SAS 12Gb/s connection the drive cannot operate at its rated throughput or integrate into the intended enterprise storage infrastructure.

Questions about this item

Will the 15mm height fit my 2.5-inch drive bay?

The drive measures 15mm tall, 70.1mm wide and 100.6mm deep, so it fits standard 2.5-inch bays that accept 15mm drives.

How do I connect the SAS 12Gb/s interface, and what step is often missed?

Insert the drive into a SAS backplane or cable, then configure the controller to enable 12Gb/s link speed; the step often missed is setting the correct link rate in the controller BIOS.

When should I plan to replace the drive based on its endurance rating?

The MLC NAND is rated for 2,000,000 hours MTBF; monitor SMART wear indicators and replace when the media-wear metric approaches the rated limit.
