Capacity and interface

The IBM 18R1086 18R1085 is a 1.2TB enterprise hard drive with a 2.5 inch form factor and a SAS 6Gb/s interface. It spins at 10000 RPM and includes a 64MB cache for demanding workloads.

Enterprise workloads

This drive suits servers and storage arrays that require sustained throughput and low latency for transactional databases or virtualisation. It is not for systems that lack a SAS backplane or HBA, nor for builds where a 3.5 inch bay is the only option.

10000 RPM spindle speed

The 10000 RPM spindle speed is the specification that determines whether this drive meets the random I/O performance target of the deployment. Verify that the host controller supports SAS 6Gb/s before ordering.

Questions about this item

Will the 2.5 inch form factor fit my server drive bay?

The 2.5 inch form factor fits standard 2.5 inch SAS drive bays and hot-swap trays used in enterprise servers and storage arrays.

How is the bare drive installed, and what step is often missed?

Mount the bare drive into a compatible 2.5 inch SAS tray or caddy, connect the SAS data and power connector, then configure the drive in the RAID controller BIOS before use.

When should I plan to replace this 10000 RPM enterprise drive?

Replace the drive when SMART attributes report reallocated sectors, excessive seek errors, or when the RAID controller flags a predictive failure alert.
