Description
Drive Feature
The Western Digital Ultrastar DC HC550 18TB 7.2K RPM SAS-12GBPS 512MB Enterprise Hard Drive (WUH721818AL5201) is a high-capacity, high-performance hard drive designed for enterprise storage systems and data centers. It has a storage capacity of 18 terabytes and rotates at 7,200 RPM (revolutions per minute) to provide fast data access. The drive uses the SAS-12GBps interface, which provides a higher data transfer rate than SATA, and has a large 512MB buffer to help improve performance. The Ultrastar DC HC550 is designed to handle heavy workloads and features advanced technologies such as vibration and shock protection to ensure data integrity and reliability. This drive is suitable for use in large-scale storage systems, data centers and enterprise applications that require high capacity and high performance.
Drive Compatibility
The hard drive is compatible with servers and storage systems that support SAS (Serial Attached SCSI) interface and have a 12 Gbps SAS host connection. It also requires a power supply that can provide the necessary 12V and 5V power for the drive. Additionally, it is recommended to check the drive’s dimensions and mounting requirements to ensure compatibility with the physical space of the device in which the drive will be installed.
Hot-Swap Compatible Drive
The Western Digital Ultrastar DC HC550 18TB hard drive is hot-swappable, meaning it can be removed and replaced without shutting down the system. However, it is important to note that hot-swap capability depends on the server or storage system in which the drive is installed. The server or storage system must also have a hot-swap backplane and support hot-swap drive bays.
It’s also worth noting that it’s always important to follow the correct procedure for hot-swapping a drive to avoid data loss or damage to the drive and system.
