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.

Spørgsmål om denne vare
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.
