861683-X21 HPE 4TB 7.2K RPM 3.5inch LFF Digitally Signed Refurbished

A hard disk drive (HDD) is a storage device that stores digital data on spinning disks called platters. A 4TB HDD is a type of hard drive that can store up to 4 terabytes of data.

The 861683-X21 HPE 4TB 7.2K RPM 3.5inch LFF Digitally Signed SATA 6GBPS Midline Hard Drive is a specific model of 4TB hard drive made by Hewlett Packard Enterprise (HPE).

The "7.2K RPM" in the model number indicates the drive's rotational speed in revolutions per minute. In this case, the drive spins at 7,200 revolutions per minute, which is a standard speed for mid-range hard drives.

The "3.5inch LFF" refers to the physical size of the hard drive. It is designed to fit into a 3.5-inch drive bay in a computer or server. "LFF" stands for "large form factor," which means the drive is larger than the standard 2.5-inch form factor used for some laptops and smaller devices.

The "Digitally Signed SATA 6GBPS" indicates that the drive uses the Serial ATA (SATA) interface for data transfer and is capable of transferring data at speeds of up to 6 gigabits per second.

Finally, "Midline" is a term used by HPE to indicate that this drive is designed for use in mid-range storage applications, such as network-attached storage (NAS) systems or data centers. It is not intended for high-performance applications like gaming or video editing.

The HPE 4TB 7.2K RPM 3.5inch LFF Digitally Signed SATA 6GBPS Midline Hard Drive provides several features for data protection and security. Some of these features include:

• Digitally Signed Firmware: The hard drive's firmware is digitally signed to ensure that it has not been tampered with or modified in any way. This ensures that the drive is authentic and that it has not been compromised by a third party.
• Self-Encrypting Drive (SED): The hard drive has built-in encryption technology that protects data from unauthorized access. The SED automatically encrypts all data written to the drive and decrypts all data read from the drive, without the need for user intervention.
• Secure Erase: The hard drive includes a secure erase feature that allows users to securely erase all data on the drive, making it impossible to recover any data from the drive.
• Advanced Data Guarding: The hard drive includes advanced data guarding features that protect data from errors or failures. These features include data parity checking and error correction.
• RAID Support: The hard drive supports RAID (Redundant Array of Independent Disks) configurations, which provide additional data protection by storing data across multiple hard drives. RAID configurations can provide redundancy and data recovery in the event of a hard drive failure.

The HPE 4TB 7.2K RPM 3.5inch LFF Digitally Signed SATA 6GBPS Midline Hard Drive (part number 861683-X21) is designed for high reliability in demanding data center environments. Here are some features and characteristics that contribute to its high reliability:

• Digitally signed firmware: The firmware on this hard drive is digitally signed by HPE, which helps prevent unauthorized modifications that could compromise the integrity of the drive or data stored on it.
• 7.2K RPM rotational speed: The higher rotational speed of 7,200 revolutions per minute (RPM) helps to reduce latency and improve performance, which is particularly important for enterprise workloads that require fast access to data.
• 4TB storage capacity: With a capacity of 4TB, this hard drive provides ample storage space for large amounts of data, reducing the need for multiple drives and simplifying storage management.
• SATA 6Gbps interface: The SATA 6Gbps interface provides fast data transfer rates and helps to ensure that data is transmitted reliably and with minimal errors.
• Midline class: This hard drive is classified as "midline," which means it is designed for 24x7 operation and is suitable for use in applications that require high capacity and reliability, such as data warehousing, data mining, and archival storage.
• HPE Smart Carrier: The HPE Smart Carrier design helps to ensure that the hard drive is installed correctly and securely, reducing the risk of data loss due to accidental disconnection or other installation errors.
• HPE quality and testing: HPE has a rigorous testing and quality control process for its hard drives, which includes testing for compatibility with HPE servers and storage systems, as well as for reliability and performance under a range of operating conditions.
