Seagate ST91000640SS Constellation 1TB 7200RPM 6Gbps SAS 2.5in internal hard drive
A 2.5in SAS hard drive holding 1000GB at 7200RPM with 64MB cache and 1.4M-hour MTBF for 24×7 enterprise use
- 1TB capacity for dense data storage
- 7200RPM spindle speed for fast sequential access
- 6Gbps SAS interface for reliable enterprise connectivity
- 64MB cache buffer to accelerate read/write operations
- 4M hours MTBF rating for 24×7 nearline reliability
Drive identity
This is a Seagate Constellation 2.5-inch SAS hard drive with a 1000GB capacity spinning at 7200RPM and a 64MB buffer. It connects through a 6Gbps SAS interface and is rated for 24×7 operation with a 1.4M-hour MTBF. The 2.5-inch form factor allows high density in space-constrained bays.
Who it suits
It suits administrators expanding nearline storage arrays or servers that require SAS connectivity and enterprise-class reliability. It is not for builds that lack a SAS backplane or controller. Buyers who need a different interface or larger single-drive capacity should look at other parts.
Deciding specification
The 6Gbps SAS interface is the single specification that determines compatibility. Verify that the host system provides a SAS port and supporting controller before purchasing.

Fragen zu diesem Artikel
What SAS controller or backplane do I need to connect this 2.5in 6Gbps SAS drive?
A SAS host-bus adapter or RAID controller with a 6Gbps SAS port and a 2.5in drive bay or backplane that accepts SAS connectors.
Will this 7200RPM SAS drive work in a server that currently uses 3Gbps SAS disks?
Yes, the drive negotiates down to 3Gbps on older backplanes while keeping its 64MB cache and 1.4M-hour MTBF rating.
How can I verify the 64MB buffer and 7200RPM speed are active after installation?
Check the drive’s SMART data or controller BIOS; both will report 7200RPM rotational speed and a 64MB cache size.
