This article will provide a detailed explanation of the features and benefits of this hard disk drive.

Features and Specifications

The HPE 870755-B21 hard disk drive has a storage capacity of 300GB and a spindle speed of 15000RPM. It uses the Serial Attached SCSI (SAS) interface, which provides a high-speed data transfer rate of 12Gbps. The hard disk drive is designed for use in Large Form Factor (LFF) drive bays, which are typically found in enterprise-class servers and storage systems.

The hard disk drive uses a 512n sector format, which means that each sector contains 512 bytes of data. This format is commonly used in enterprise-class storage systems and provides a higher level of data integrity and reliability than other sector formats.

The hard disk drive also features hot-swappable capability, which means that it can be replaced while the server or storage system is still running. This allows for easy maintenance and upgrades without interrupting the operation of the system.

Digital Signature

One of the unique features of the HPE 870755-B21 hard disk drive is its digitally signed firmware. This means that the firmware on the hard disk drive has been digitally signed by HPE to ensure that it has not been tampered with or modified in any way.

This feature provides an additional layer of security for the data stored on the hard disk drive. It helps to prevent malicious attacks that may attempt to modify the firmware on the hard disk drive to gain access to sensitive data.


The HPE 870755-B21 hard disk drive comes with a tray that is specifically designed for use with the drive. The tray provides a secure and stable mounting platform for the hard disk drive, which helps to prevent damage to the drive during installation and operation.

The tray also provides a standardized form factor that allows the hard disk drive to be easily installed in a wide variety of server and storage systems. This ensures that the hard disk drive is compatible with a wide range of hardware configurations, which helps to simplify the deployment process for IT administrators.


The HPE 870755-B21 hard disk drive provides a number of benefits for enterprise-class data centers. These benefits include:

  • High Performance: The 15000RPM spindle speed and 12Gbps data transfer rate provide a high level of performance, which is essential for data-intensive applications such as databases and virtualization.
  • High Reliability: The 512n sector format and digitally signed firmware provide a high level of data integrity and reliability, which is essential for mission-critical applications.
  • Easy Maintenance: The hot-swappable capability and standardized form factor of the hard disk drive make it easy to replace and upgrade without interrupting the operation of the system.
  • Enhanced Security: The digitally signed firmware provides an additional layer of security for the data stored on the hard disk drive, which helps to prevent unauthorized access and data breaches.

Overall, the HPE 870755-B21 300GB 15000RPM SAS 12GBPS LFF Sc 512n Hot Swap Digitally Signed Hard Disk Drive with Tray is a high-performance, enterprise-class hard disk drive that provides a wide range of benefits for modern data centers.

The Serial Attached SCSI (SAS) hard drives have become increasingly popular for their increasing use in high-end workstations and servers. These drives are employed in consumer desktops and modern servers for their speed and reliability. Enterprises have made the SAS hard drives their de-facto standard. Now, the 12Gbps speed throws the usefulness of these drives up a notch.

Most professional hosting providers now use SAS 12Gbps hard drives for data production. These drives have proven useful in high input/output operations and critical website functions. Users trust these drives because there is no risk of data loss, corruption, or downtime.

Faster Throughput

SAS 12Gbps drives read, write, and process data within split seconds. The latest 12Gbps disks use the latest RAID hardware technology to offer faster data transfer and recovery rates. They are perfect for sequential data, high workloads, and random IOPS alike.

This function allows them to be best suited for servers that have 100 percent duty cycles. They do not only work with desktops and PCs, but they can read/write data 24/7.

Higher Performance

SAS 12Gbps HDDs have received the utmost attention in the market as a result of their high performance. These performance benefits allow it to be useful for a wide variety of applications. For instance, a SAS 12Gbps connection can support up to four wide lanes per connection.

Connecting JBOD with these SAS drives can support up to 1200MB/s. These high-performance drives do not only help handle large workloads; they also offer cost-effective expansion to an already robust system.

Also, each 12Gbps high-performance SAS drive can offer users a rotational speed of up to 15000 rpm.

They provide a great bandwidth enough to perform efficiently. The robust performance of SAS 12Gbps drives clearly a worthy investment for improved performance of servers and desktops. They provide very large amounts of storage options and are a cost-effective choice for users.

Utmost Flexibility

Flexibility is one of the best benefits of SAS 12Gbps drives. These drives have configured flexibility, which allows them to work perfectly with several devices without modification or changes. Many of them feature a Universal Serial controller for seamless system support.

SAS 12Gbps hard drives can also be partitioned into a storage pool and assigned to servers for work-intensive applications. They are a perfect fit for server systems, including reservation systems, medical imaging, and more!

Only this range of SAS hard drives can provide users with the best worlds of flexibility. This way, allows them to support use with other drives.

Increased Availability

12Gbps SAS-based storage systems have the benefit of dual-port capability. This allows them to provide a redundant path to the drives in case of controller failover. These drives also operate on separate point-to-point connections. That way, it is rare for drive connection loss to affect them.

SAS 12Gbps HDDs are built to handle the rigours of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.
