Product Identity

This is a refurbished IBM 900GB 10000 RPM SAS hard drive in a 2.5-inch hot-swap tray. It is built for server storage arrays that require a 6Gb/s SAS connection. The drive carries manufacturer part numbers 81Y9651 and 81Y9650. It is listed as compatible with the IBM System x3650 M3 server.

Fit and Alternatives

This drive suits administrators replacing a failed disk in a compatible SAS bay or expanding an existing 6Gb/s array. Buyers who need a larger single volume or a different interface should look elsewhere. The hot-swap tray is included, so no separate caddy is required for supported bays. It is not intended for consumer desktop PCs lacking SAS backplanes.

Deciding Specification

The interface is SAS 6Gb/s, which determines whether the drive will communicate with your controller or backplane. Verify that your system accepts 2.5-inch SAS hot-swap drives before purchase. The 10000 RPM spindle speed and 900GB capacity are fixed characteristics of this model.

Questions about this item

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

The SAS 6Gb/s link tops out at 6 gigabits per second, so sustained throughput cannot exceed that bandwidth ceiling.

What does the 2.5-inch hot-swap tray need to fit?

The drive with its tray fits a standard 2.5-inch SFF hot-swap bay in compatible IBM System x3650 M3 servers.

How is the hot-swap drive installed, and what step is often missed?

Slide the tray into the bay until the latch clicks; the step people miss is not pushing far enough to fully seat the SAS connector.
