Product Specifications Of Dell 900GB SAS 12GBPS 15K RPM 4KN

The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive is a high-performance storage device designed for use in enterprise-level data centers. It provides a high-speed SAS interface, a rotation speed of 15,000 RPM, and a storage capacity of 900GB. This article will provide a detailed explanation of each of these features and their benefits in terms of performance, reliability, and compatibility.


The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive has a capacity of 900GB, making it an ideal storage device for large-scale data centers. With this capacity, it can store large amounts of data, such as databases, virtual machines, and other mission-critical applications.

The high capacity of this hard drive ensures that there is enough space to store large data sets and enables data center managers to reduce the number of hard drives required to store the same amount of data. This, in turn, can result in cost savings and a reduction in the overall complexity of the storage environment.

Rotation Speed

The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive has a rotation speed of 15,000 RPM. The high rotation speed is one of the key features that makes this hard drive a high-performance storage device. The high rotation speed enables the hard drive to read and write data at faster rates than slower hard drives.

This speed is essential for applications that require high-speed data access, such as online transaction processing (OLTP), data warehousing, and virtualization. With faster data access, applications can perform more efficiently and improve the overall performance of the data center.

SAS Interface

The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive features a SAS interface that provides a high-speed data transfer rate of 12Gbps. The SAS interface is a more advanced interface than SATA and SCSI interfaces and provides faster data transfer rates.

The SAS interface is also more reliable and robust than SATA and SCSI interfaces. It supports dual-ported drives, which allows for high availability and fault tolerance in the data center. This means that if one port fails, the other port can continue to provide access to the data, ensuring that the data is always available.

4KN Sector Size

The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive features a 4K native sector size, which is a more efficient way of organizing and storing data on the hard drive. This sector size allows for more efficient use of storage space, reducing the amount of wasted space on the hard drive.

The 4KN sector size also provides a higher level of data integrity and reliability. This is because the larger sector size reduces the number of sectors required to store data, which in turn reduces the likelihood of errors occurring during read and write operations.


The 400-ATIW Dell 900GB SAS 12GBPS 15K RPM 4KN SFF hard drive is compatible with a wide range of Dell PowerEdge servers and storage arrays. This compatibility ensures that the hard drive can be easily integrated into existing data center environments without the need for additional hardware or software.

The hard drive is also compatible with a wide range of operating systems, including Windows, Linux, and VMware. This ensures that the hard drive can be used with a variety of applications, providing flexibility and ease of use for data center managers.
