Details Information

The 400-AZXD Dell 12TB 7.2K RPM SAS-12GBPS 256MB 512E 3.5Inch LFF Hard Drive is a type of hard disk drive (HDD) used for data storage. It is designed to work in server environments where high capacity storage and reliability are important.

Here is a breakdown of the key specifications of this hard drive:

12TB: This refers to the amount of storage capacity the hard drive has. This is a large amount of storage and is suitable for storing large amounts of data such as videos, images, and other files.

7.2K RPM: This stands for revolutions per minute and refers to the speed at which the hard drive's platters spin. A higher RPM means faster data access and transfer speeds. 7.2K RPM is considered a standard speed for enterprise-grade hard drives.

SAS-12GBPS: This refers to the interface used to connect the hard drive to the computer. SAS (Serial Attached SCSI) is a high-speed, serial data transfer interface for connecting storage devices to a computer. SAS-12GBPS is the latest version of SAS interface and provides faster data transfer speeds compared to older versions.

256MB Buffer: This refers to the amount of memory used as a buffer for data transfer between the hard drive and the computer. A larger buffer can improve performance by allowing the hard drive to cache frequently-accessed data.

512E: This refers to the format of the hard drive. 512E format hard drives use larger physical block sizes than traditional 512n hard.


The performance of the 400-AZXD Dell 12TB 7.2K RPM SAS-12GBPS 256MB 512E 3.5Inch LFF Hard Drive will depend on several factors, including the specific usage and conditions it will be subjected to. However, in general, hard drives with similar specifications tend to have relatively high performance.

Here are some of the key performance-related specifications of this hard drive:

  • 7.2K RPM: This hard drive has a rotation speed of 7.2K RPM, which is considered a standard speed for enterprise-grade hard drives. This means that it can access and transfer data quickly, which can improve the overall performance of the server.
  • SAS-12GBPS: This hard drive uses SAS-12GBPS interface which supports a maximum data transfer rate of 12 Gbps, which is faster than other interfaces like SATA.
  • 256MB Buffer: The hard drive has a buffer size of 256MB, which can help to improve performance by caching frequently-accessed data.
  • 512E format: The hard drive is in 512E format, which allows for more efficient use of disk space and improved performance for large files. This can help to reduce the number of read/write cycles on the drive and prolong its lifespan.

It's worth mentioning that the performance of hard drives can also be affected by factors such as usage patterns, operating conditions, and maintenance. Additionally, the 12TB capacity of this hard drive may make it more prone to performance degradation, since the larger the storage capacity the more complex the hard drive is and the more vulnerable it can be.

Drive Compatibility

The 400-AZXD Dell 12TB 7.2K RPM SAS-12GBPS 256MB 512E 3.5Inch LFF Hard Drive is designed to be compatible with servers that support the SAS interface, ensuring that the server has a SAS interface and the appropriate cables to connect the hard drive is important.

Here are some of the key compatibility considerations for this hard drive:

  • Form factor: The hard drive has a 3.5-inch form factor, which is typically used in servers. Ensure that your server's drive bay can accommodate a 3.5-inch drive.
  • SAS interface: The hard drive uses the SAS interface to connect to the server. Ensure that your server has a SAS interface and the appropriate cables to connect the hard drive.
  • Power requirements: The hard drive requires a 12V power supply, ensure that your server can provide the appropriate power to the drive.
  • Operating System: The hard drive is compatible with a wide range of operating systems, including Windows, Linux, and macOS. It's important to ensure that the operating system on the server is compatible with the hard drive and that the necessary drivers and software are installed.
  • RAID system: The hard drive can be used as a standalone drive or as part of a RAID array, ensure that the RAID controller in your server is compatible with the hard drive.

It's always recommended to check the server's technical documentation or consult with the manufacturer to confirm compatibility before purchasing or installing the hard drive.

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.
