1 TB SAS drive for servers
This 1 TB SAS hard drive spins at 7200 RPM and uses a 6.0 GB/sec interface. It is built for server and storage units that require hot-plug capability. The drive ships with a hotswap tray attached for direct installation.
Suits arrays needing hot-plug SAS drives
Administrators expanding SAS-based arrays with 2.5 inch bays will find this drive compatible. Systems limited to SATA-only controllers cannot use this drive. Buyers who need larger capacities should look at other models.
6.0 GB/sec SAS interface
The drive connects through a 6.0 GB/sec SAS interface, which determines host-controller compatibility. Verify that your backplane or controller supports this speed before purchase.

Fragen zu diesem Artikel
Should I choose the 1 TB capacity or a larger version of this Constellation.2 drive?
Only the 1 TB capacity is offered for the ST91000640SS model, so no larger version of this exact drive exists.
What does the 6.0 GB/sec transfer rate mean once the drive is installed in a server?
The 6.0 GB/sec SAS interface sets the maximum link speed; real-world throughput will be lower and depends on the controller and workload.
Is the SAS interface on this drive compatible with standard SATA controllers?
No, the ST91000640SS uses a native SAS interface and requires a SAS HBA or RAID controller; it will not work on a SATA-only port.
