300 GB 15K SAS Server Drive
The IBM 49Y1856 is a 300 GB 3.5-inch internal hard drive spinning at 15000 RPM with a SAS 6Gb/s interface. It is supplied as a bare drive in new condition and is designed for server environments that demand high rotational speed and a serial-attached SCSI connection.
Server Builders Needing 15K SAS
This drive suits administrators upgrading or repairing SAS-based storage arrays that specifically require a 15K spindle speed and a 3.5-inch form factor. It is not for buyers who need larger capacity per spindle, for systems that only accept interfaces other than SAS, or for quiet desktop PCs where acoustic noise is a concern.
15000 RPM Spindle Speed
The single specification that decides fitment is the 15000 RPM rotational speed combined with the SAS 6Gb/s interface. The controller and backplane must support this signalling rate and the physical 3.5-inch hot-swap tray type for the drive to operate correctly.

Questions about this item
Which capacity of the IBM 49Y1856 should I choose for a server array?
The drive is offered in a single 300GB capacity, so there is no alternative version to select.
What does the 15000 RPM rating mean for real-world server performance?
The 15000 RPM spindle speed delivers low average latency and high IOPS for transaction-heavy workloads such as databases.
What does the SAS 6Gb/s interface limit in practice?
The SAS 6Gb/s interface sets the maximum bus transfer rate between the drive and the controller.
