2 TB SAS 12 Gb/s drive

This 2 TB SAS 12 Gb/s drive fits servers and storage arrays that require a 2.5 inch form factor. The 128 MB cache helps smooth mixed read and write workloads. It is built for environments that demand enterprise SAS connectivity.

Capacity and headroom

Two terabytes provide room for operating systems, databases and application data on a single spindle. The 7 200 RPM spindle delivers consistent throughput for sequential workloads. Random I/O intensive tasks will reach the mechanical limits of a single drive.

Build and connectors

The 2.5 inch SAS connector enables hot-plug backplanes and multi-path cabling in rack enclosures. A 12 Gb/s interface supports current controller generations without negotiation bottlenecks. The drive is supplied new in OEM or retail packaging that may vary.

Questions about this item

Will the SAS 12Gb/s interface work with my existing 6Gb/s SAS backplane?

Yes, the drive negotiates down to 6Gb/s on older backplanes while keeping its 7200 RPM spindle speed and 128MB cache.

How can I confirm the drive is running at full 12Gb/s after installation?

Check the controller BIOS or OS utility; it should report a negotiated link speed of 12Gb/s and show the 2TB capacity with 128MB cache active.

Does the package include a 2.5" to 3.5" mounting bracket or SAS cables?

The drive ships in OEM packaging with the XY986 unit only; brackets and SAS cables must be sourced separately.
