In this comprehensive guide, we will delve into the features and benefits of the Dell 400-BOZY SAS 12GBPS hard drive. This 22 Terabyte (TB) hard drive operates at 7.2K Revolutions Per Minute (RPM) and boasts a 512 Megabytes (MB) buffer, ensuring data retrieval and storage efficiency. We will also explore its 512e technology and its hot plug capability, along with compatibility with Dell EMC 14g, 15g, and 16g servers.

The Dell 400-BOZY is a Serial-Attached SCSI (SAS) hard drive designed to meet the ever-increasing demands of data storage in the enterprise world. This storage solution offers a remarkable 22 Terabytes of storage capacity, operates at 7,200 revolutions per minute (RPM), features a 512 Megabytes (MB) buffer, supports 512e technology, and boasts a hot plug capability. It is specially engineered to be compatible with Dell EMC 14g, 15g, and 16g servers.

In the digital age, data has become the lifeblood of businesses, organizations, and individuals alike. Storing, managing, and accessing data efficiently is essential for smooth operations and decision-making. Data storage solutions come in various forms, ranging from traditional hard disk drives (HDDs) to advanced solid-state drives (SSDs).

Understanding Serial-Attached SCSI

Serial-attached SCSI, commonly known as SAS, is a data storage interface technology that provides a balance between the high performance of traditional SCSI (Small Computer System Interface) and the compatibility and reliability of Serial Advanced Technology Attachment. SAS 22TB technology is widely used in enterprise-grade storage devices, including hard drives and SSDs, to ensure fast data transfer, high reliability, and scalability.

Benefits of SAS Technology

High data transfer rates

SAS supports data transfer speeds of up to 12 Gigabytes Per Second (Gbps), making it ideal for applications with high I/O (Input/Output) requirements.


SAS drives are known for their robustness and are designed for continuous operation in demanding environments.


SAS supports daisy-chaining multiple devices, allowing for easy expansion of storage capacity.
Error recovery and correction: SAS drives are equipped with error-checking and correction mechanisms to ensure data integrity.


SAS is backward compatible with SATA, making it versatile for various system configurations.

Impressive Storage Capacity

The Significance of 22 Terabytes

The 22 Terabytes (TB) storage capacity of the Dell 400-BOZY SAS hard drive is a standout feature. This substantial storage space is essential for modern enterprises, as the volume of data generated and processed continues to grow exponentially. Whether it's for storing critical business data, multimedia content, or large databases, having a high-capacity storage solution like the Dell 400-BOZY is invaluable.

Storage Needs for Modern Enterprises

  • Data analytics: Storing and analyzing vast amounts of data for insights and decision-making.
  • Virtualization: Managing virtual machines and their associated data.
  • Backup and disaster recovery: Safeguarding critical data to prevent data loss.
  • Archiving: Storing historical data for compliance and reference.

High-Speed Performance

The Role of RPM in Hard Drives

The revolutions per minute (RPM) of a hard drive's platters directly affect its data access speed. A higher RPM generally leads to faster data retrieval. In the case of the Dell 400-BOZY, it operates at 7,200 RPM, which is a common speed for enterprise-grade hard drives.

7.2K RPM in Dell 400-BOZY

The 7.2K RPM speed of the Dell 400-BOZY SAS hard drive ensures that it can access and transfer data swiftly. This is especially important in enterprise environments where quick data access is critical for various applications, including databases, virtualization, and real-time data processing.

Efficient Data Retrieval

The Importance of Buffer Size

The buffer, often referred to as the cache, is a small amount of high-speed volatile memory inside a hard drive. It acts as a temporary data storage area, allowing the hard drive to read and write data more efficiently.

512 Megabytes Buffer in Dell 400-BOZY

The Dell 400-BOZY is equipped with a generous 512 Megabytes (MB) buffer. This substantial buffer size allows the hard drive to temporarily store and process data before it's written to or read from the platters. As a result, data retrieval and storage operations become more efficient, reducing latency and enhancing overall performance

Exploring 512e Technology

The term "512e" refers to the Advanced Format standard for hard drives. In this context, "512e" signifies that the drive emulates the traditional 512-byte sector size while using a larger, more modern physical sector size of 4,096 bytes. This technology was introduced to accommodate the increasing storage capacity of hard drives and improve data integrity.

Benefits of 512e for Storage

The use of 512e technology in the Dell 400-BOZY SAS hard drive offers several advantages

  • Enhanced storage density: 512e technology enables higher data storage density on the drive, allowing for larger capacities.
  • Improved error correction: The larger physical sectors provide better error correction capabilities, reducing the risk of data corruption.
  • Compatibility: 512e technology ensures compatibility with legacy systems and applications that expect 512-byte sectors.

Hot Plug Capability

Understanding Hot Plug

Hot plug, also known as hot swapping, is a feature that allows users to replace or add hardware components without shutting down the system. In the context of hard drives, hot-plug capability means that you can insert or remove a hard drive while the server or storage array is still operational.

Hot Plug in Dell 400-BOZY

The Dell 400-BOZY SAS hard drive is hot plug-enabled, which is a valuable feature for businesses that require continuous operation and minimal downtime. This capability simplifies maintenance and upgrades by allowing IT administrators to add or replace hard drives without disrupting the entire system

Compatibility with Dell EMC Servers

Dell EMC Server Series

Dell EMC is a renowned brand in the server industry, known for its high-quality server hardware and solutions. The Dell 400-BOZY SAS hard drive is specifically designed for compatibility with Dell EMC servers, including the 14th, 15th, and 16th generation server series.

Dell 400-BOZY Compatibility

The compatibility of the Dell 400-BOZY with Dell EMC servers ensures seamless integration and optimal performance. Whether you have a Dell EMC PowerEdge server or a different model from the 14g, 15g, or 16g series, you can trust that the Dell 400-BOZY hard drive will work seamlessly with your system.
