Product Overview of Dell 400-AENN

A 400-AENN Dell 4TB 7.2K RPM SATA-6GBPS 3.5inch Hot-swap Hard Drive is a type of hard drive that is commonly used in servers and enterprise-grade storage systems. In this article, we will discuss the various features and specifications of this hard drive, including its size, storage capacity, speed, interface, and form factor.

Form Factor

The form factor of the 400-AENN Dell hard drive is 3.5 inches. This means that it has a diameter of 3.5 inches, which is a standard size for many server and storage systems. The 3.5-inch form factor is typically used for high-capacity hard drives that require a larger physical size to accommodate the disks and other components.

Storage Capacity

The 400-AENN Dell hard drive has a storage capacity of 4 terabytes (TB). This means that it can store up to 4 trillion bytes of data. 4TB is a very high storage capacity, and it is ideal for storing large amounts of data, such as video files, photos, documents, and other digital assets. The high storage capacity of this hard drive makes it ideal for use in servers and storage systems that require a large amount of storage space.


The 400-AENN Dell hard drive has a rotational speed of 7,200 revolutions per minute (RPM). This means that the disks inside the hard drive spin at a rate of 7,200 RPM. A higher RPM means that the disks spin faster, which can result in faster data access times and faster data transfer speeds. The 7,200 RPM speed of this hard drive makes it a fast and reliable storage solution.


The 400-AENN Dell hard drive uses the Serial ATA-6Gbps (SATA-6Gbps) interface. This is a type of interface that is commonly used in modern hard drives and other storage devices. SATA-6Gbps provides a high-speed data transfer rate of up to 6 gigabits per second (Gbps), which is six times faster than the previous SATA-3Gbps interface. The SATA-6Gbps interface is also backward compatible with the previous SATA interface, which means that it can be used with older systems that only support SATA-3Gbps or SATA-1.5Gbps.

Hot Swap Capability

The 400-AENN Dell hard drive has a hot-swap capability, which means that it can be replaced or removed from a server or storage system without having to shut down the system. This feature allows for easy and convenient replacement of hard drives without interrupting the operation of the system. Hot-swapping is a common feature in many enterprise-grade storage systems, as it helps to minimize downtime and maintain system uptime.


The 400-AENN Dell hard drive is compatible with a wide range of server and storage systems. It is specifically designed for use in Dell PowerEdge servers, but it can also be used in other servers and storage systems that support the 3.5-inch form factor and the SATA-6Gbps interface. Before purchasing this hard drive, it is important to ensure that your system is compatible with it, and that it meets the necessary requirements for installation and operation.

Overall, the 400-AENN Dell 4TB 7.2K RPM SATA-6GBPS 3.5inch Hot-swap Hard Drive is a high-capacity, fast, and reliable storage solution that is ideal for use in servers and enterprise-grade storage systems. Its 3.5-inch form factor, 4TB storage capacity, 7,200 RPM speed, SATA-6Gbps interface, and hot-swap capability make

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

When it comes to storing files and processing information, it is difficult to shove the impressive SATA hard drives aside. Although many people tend to regard hard disk drives as old technology, the new highly-performing variants have raised the bar. One of the most impressive variants is hard drives with the SATA interface and transfer speed of up to 6Gbps.

These are among the best drives to buy presently. They come with flash-speed disks that load several times faster than traditional hard drives. Another added advantage is that they come in either 2.5-inch sizes or 3.5-inch sizes. Users can find SATA 6Gbps hard drives that will nicely fit their case or enclosure.

SATA 6Gbps hard drives are designed to offer maximum performance. They connect to servers, PCs, or desktop computers via SATA 6Gbps cables. Despite their compact 2.5" to 3.5" sizes, they feature a dynamic cache of up to 64MB. Having these types of storage devices in hand will improve work efficiency and productivity.

Improved Storage Capacity and Performance

There are SATA 6Gbps hard drives that can give users a blend of HDD and SSD functionality. A device that can give a synergistic effect on both storage units will surely offer a higher level of performance. Users will find drives with traditional storage capacity up to 22TB. Most of these drives also come along with NAND technology for enhanced performance.

The read-write speed is something that will give users optimum satisfaction. With the SATA 6Gbps interface, users can expect a read speed of up to 400MB/s. Not only that, but some drives also run at up to 10000 rpm. Even at that rate, they are generally quiet, and they generate less heat.

Drives that use the SATA 6Gbps interface have been built to learn users' most used applications effectively. This engineering allows them to load those applications faster. It also helps gaming consoles to load the games initially after users have launched the game. There is everything to get excited about when it comes to these drives.

The point of the SATA 6Gbps interface is to enhance the quality of traditional mechanical hard drives. They are available at different capacity choices and RPM choices.

Reliable Data Recovery

There are possibilities of data accidents such as accidental deletion, formatting, virus attack, unexpected power shutdown, and partition loss. If such losses occur, data recovery software can easily recover the data from SATA 6Gbps hard drives. Data can be easily recovered, undelete, and unformatted from these SATA hard drives

Dynamic Cache

The dynamic cache is one of these drives most impressive features despite not being so evident to users. It improves the performance of the SATA 6Gbps drives in real time with optimized cache allocation. This function allocates more cache towards the read and writes functions. That is why users will find that read and write speeds are usually almost equal.
