Description
The HP 695510-B21 is a high-capacity enterprise-grade hard drive, offering 4TB of storage space. It utilizes the Serial Attached SCSI (SAS) interface, which is the standard for high-performance servers and storage systems due to its reliability, scalability, and speed. The drive operates at a rotational speed of 7200 RPM, providing a good balance between performance and power consumption for demanding enterprise workloads. With a data transfer rate of 6Gb/s, this SAS drive ensures rapid data access and transfer, crucial for applications such as databases, virtualization, and large file processing. The 3.5-inch form factor is standard for enterprise servers and direct-attached storage (DAS) enclosures. Many enterprise SAS drives, including this model, are designed to be hot-swappable, allowing for drive replacement or addition without shutting down the server, thereby minimizing downtime. This 4TB SAS drive is an ideal choice for HP ProLiant servers and other enterprise storage solutions that require significant capacity, robust performance, and the reliability associated with SAS technology. It is built to withstand the continuous operation demands of data centers and mission-critical environments, making it suitable for RAID configurations and high-availability storage pools.
