Description
Product Overview
Product Overview provides a general description of the Hitachi 4TB 7200RPM SAS 12GBPS 128MB SE Hard Drive (0F22815).
The Hitachi 4TB 7200RPM SAS 12GBPS 128MB SE Hard Drive is a high-performance hard drive designed for use in enterprise-class servers and storage systems. It has a capacity of 4TB, which is capable of storing a large amount of data. The hard drive has a 7200 RPM rotation speed and a 128MB buffer size, which provides fast data access and improved system performance. It uses SAS (Serial Attached SCSI) interface, which is a high-speed, serial data transfer interface designed for data storage applications. The hard drive also supports a maximum data transfer rate of 12 Gbps, which is the fastest data transfer rate available for SAS interface. The drive is built with security and data protection features such as Self-Encrypting Drive (SED) and TCG Enterprise support, making it a reliable and secure storage solution for sensitive data.
Interface and Data Transfer Rate
“Interface and Data Transfer Rate” refers to the interface used to connect the hard drive to a computer or storage system and the maximum speed at which data can be transferred between the drive and the host.
Interface: The Hitachi 4TB 7200RPM SAS 12GBPS 128MB SE Hard Drive (0F22815) uses SAS (Serial Attached SCSI) interface, which is a high-speed, serial data transfer interface designed for data storage applications. SAS interface supports faster data transfer rates and allows for multiple hard drives to be connected to a single host.
Data Transfer Rate: The hard drive supports a maximum data transfer rate of 12 Gbps, which is the fastest data transfer rate available for SAS interface. This high data transfer rate allows for faster data access and improved system performance. With the 12 Gbps SAS interface, it allows for faster data transfer rates and more efficient communication between the drive and the host. It also supports backward compatibility with SAS 6 Gbps and SAS 3 Gbps, allowing it to be used in a variety of different systems.
Hot-Swap Capabilities
Hot-Swap Capabilities” refers to the ability of a hard drive to be easily replaced or exchanged without shutting down the system.
The Hitachi 4TB 7200RPM SAS 12GBPS 128MB SE Hard Drive (0F22815) has Hot-Swap capabilities which means it can be removed and replaced while the system is still powered on. This feature allows for easy maintenance and upgrades without disrupting the operation of the system. Hot-swap capability allows for easy replacement of failed drives and upgrades to the system without the need for a system shut-down, reducing downtime and increasing system availability. It also allows for easy integration into hot-swap drive bays in servers or storage systems. This feature makes it ideal for use in high-availability environments such as data centers, where minimizing downtime is a key consideration.
