Enterprise 4 TB SAS 12Gb/s drive

The Seagate ST4000NM0065 is a 3.5-inch internal hard drive built for enterprise storage arrays and servers. It delivers 4 TB of capacity on a 12Gb/s SAS interface with a 7200 RPM spindle and 128 MB cache. Conventional magnetic recording technology ensures consistent performance in dense, multi-drive environments.

Replaces lower-capacity nearline SAS drives

This model upgrades from smaller enterprise SAS drives when bulk-data workloads demand higher density per slot. The 550 TB per year workload rating supports 24×7 operation at ten times the endurance of desktop-class drives. Advanced write caching algorithms boost efficiency for random read and write patterns.

Verify SAS backplane and 12Gb/s controller support

Confirm your chassis accepts 3.5-inch drives with a 26.10 mm height and standard SAS power and data connectors. A 12Gb/s SAS HBA or RAID controller is required to utilise the full interface speed. The 512n sector format simplifies integration into existing RAID sets without 512e or 4Kn translation overhead.

Pitanja o ovom artiklu

Will the 26.10 mm height and 101.85 mm width fit a standard 3.5-inch drive bay?

Yes, the drive meets the 3.5-inch form-factor maximums of 26.10 mm height and 101.85 mm width, so it fits any standard bay and tray.

How do I connect the 12 Gb/s SAS interface, and what is the common mistake?

Attach a SAS 12 Gb/s cable to the drive's SAS port and a compatible controller; the frequent error is using a SATA-only backplane or controller that cannot negotiate the 12 Gb/s link.

When should I plan to replace this drive under a 550 TB-per-year workload?

The drive is engineered for 550 TB per year; divide your actual annual writes by 550 to estimate the service interval, then replace before that limit is reached.
