Ideal server storage

The IBM 81Y9691 is a 1TB 2.5" internal hard drive built for server deployment. It spins at 7200 RPM and uses a Near Line SAS interface running at 6Gb/s. A hot-swap tray is included for tool-less installation.

Suited for hot-swap bays

This drive fits 2.5" hot-swap bays in compatible servers and storage arrays. It is not for laptops, desktops or external enclosures that lack SAS backplane support. Buyers needing a different interface or a non-hot-swap form factor should look elsewhere.

6Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6Gb/s SAS connection. Your system must provide a matching SAS backplane and controller for the drive to operate. Without that interface the part will not work.

Questions about this item

How does the 7200 RPM spindle speed affect performance in a server?

The 7200 RPM speed provides consistent throughput for near-line storage workloads such as backups, archives and bulk data repositories.

What does the 6Gb/s SAS interface limit in practice?

The 6Gb/s SAS link caps maximum transfer rate at six gigabits per second, which is the ceiling for sustained reads and writes on this drive.

Will the included hot-swap tray fit a standard 2.5-inch SAS bay?

Yes, the supplied tray is designed for 2.5-inch hot-swap bays that accept SAS near-line drives.
