Enterprise 6 TB SAS drive

The Seagate ST6000NM0195 is a new 3.5-inch enterprise hard drive with a 6 TB capacity, 7200 RPM spindle speed and a 12 Gb/s SAS interface using 512e formatting. It includes a 256 MB cache and conventional magnetic recording technology designed for continuous operation in bulk-data applications. The bare drive measures 147 mm long, 101.85 mm wide and 26.10 mm high.

Suits RAID arrays and replicated servers.

This drive fits replicated and RAID multi-drive storage servers that accept a 12 Gb/s SAS connection and 512e sector format. It is built for 24x7 workloads up to 550 TB per year and handles rotational vibration in dense chassis. Systems without a SAS controller or backplane, or those requiring a SATA-only drive, cannot use this model.

12 Gb/s SAS interface with 512e format

The single specification that decides compatibility is the 12 Gb/s SAS interface combined with 512e sector formatting. Your host bus adapter, RAID controller or server backplane must support this exact interface and sector size. Average latency is 4.16 ms and the drive delivers up to 100 percent random-write improvement over the prior generation through advanced write caching algorithms.

Questions about this item

What does the 12Gb/s SAS interface cap in practice?

The 12Gb/s SAS link caps sustained throughput at the controller's maximum lane speed, so sequential reads and writes cannot exceed that bus limit even though the drive spins at 7200 RPM with a 256MB cache.

What physical clearance does the 3.5-inch form factor need to fit or mount?

The drive measures 147.00mm long, 101.85mm wide and 26.10mm high, so the bay or caddy must provide at least those dimensions plus standard side-mount screw clearance.

How is the 512e SAS drive installed, and what step do people get wrong?

Connect the SAS data and power cables, then set the controller to 512e emulation mode; the common mistake is leaving the controller in 512n or 4Kn mode, which prevents the drive from being recognised.
