Match the drive to the system
Enterprise hard drives commonly use SAS or SATA interfaces, and the distinction matters: the drive must work with the controller, backplane, and storage environment in the system. Include the server or array model when you know it, along with the controller or backplane details if the configuration is specialized. A part number from an existing drive is often the clearest reference.
Capacity, size, and sector format
State the required capacity and physical form factor, such as 2.5-inch or 3.5-inch, when specified by the chassis. Also note the sector format or logical block size required by your environment, for example 512-byte sectors or 4Kn. Similar-looking drives can differ in interface, sector format, firmware behavior, and intended workload, so these details help narrow the match.

For one replacement drive, include the exact model or part number and the quantity needed. For a larger requirement, list each capacity and interface separately, identify acceptable equivalents if you have them, and describe any system compatibility constraints.
