Built for demanding storage workloads
This drive is designed for workloads of up to 550TB per year. That makes it suitable for server environments handling substantial data activity. Check that your planned workload sits within this limit.
Its rated mean time between failures is 2.5 million hours. This figure is a reliability measure, not a promise of a particular service life. It can help when assessing drives for continuous-use storage systems.
SAS connection and physical fit
The 12 Gbit/s SAS interface requires a compatible SAS host connection. It is not a SATA drive, so confirm your system supports SAS before ordering. The 3.5-inch form factor is 147mm deep, 101.8mm wide and 26.1mm high.
Typical power consumption is 8.46W, falling to 4.74W when idle. Allow for this when planning system power and cooling.
Check your system before ordering
- Confirm your controller and host system support SAS drives.
- Check that your system has a suitable 3.5-inch bay and clearance for the drive’s dimensions.
