IBM 45W7731 450GB 10000RPM SAS 2.5" internal hard drive

Server storage drive

This 450 GB SAS hard drive spins at 10000 RPM in a 2.5 inch form factor and ships with an included cradle for direct installation in compatible server bays. The interface and rotational speed suit environments that demand consistent throughput for transactional workloads. New condition means the unit has not been previously deployed.

Enterprise SAS workloads

Database administrators and storage architects running RAID arrays or high-availability clusters will find the capacity and spindle speed match typical tier-one requirements. Buyers who need a consumer desktop drive or a silent media archive should look elsewhere because this unit is built for continuous server duty and SAS connectivity.

SAS interface requirement

The drive communicates exclusively over a SAS bus, so the host system must provide a SAS backplane or controller with the correct cabling. Without that interface the drive cannot be used, making the SAS connection the single specification that decides compatibility.
