Exceptional Compatibility

WD120EFBX is a 12TB hard drive made by Western Digital specifically designed for use in network-attached storage (NAS) systems. It has a rotation speed of 5,400 RPM and a buffer size of 256MB. The hard drive is compatible with SATA-6GB/s interface and has a 3.5 inch form factor. The "Red Plus" designation indicates that the hard drive is designed for use in a NAS system with more than 8 bays. This exceptional compatibility ensures that the hard drive is able to handle the increased workload and vibration that is common in a multi-bay NAS system.

Features and Benefits

The WD120EFBX Western Digital Wd Red Plus 12TB hard drive has several features and benefits that make it well-suited for use in a NAS system:

  • High storage capacity: With a 12TB capacity, this hard drive can store large amounts of data, making it ideal for use in a NAS system with many users or for storing large files such as videos and backups.
  • High-performance: With a rotation speed of 5,400 RPM and a buffer size of 256MB, this hard drive provides fast data transfer speeds, allowing for quick access to stored files.
  • SATA-6GB/s interface: The hard drive is compatible with the SATA-6GB/s interface, which provides faster data transfer speeds compared to previous versions.
  • 3.5 inch form factor: The 3.5 inch form factor makes the hard drive compatible with most standard internal hard drive bays, making it easy to install in a NAS system.
  • Red Plus Designation: This hard drive is designed for use in a NAS system with more than 8 bays. It is built to handle increased workload and vibration that is common in a multi-bay NAS system.
  • Improved Error Recovery: It has improved error recovery control and advanced firmware algorithms that help in recovering from errors and ensuring data is protected.
  • 24x7 Operation: It is designed for 24x7 operation, which means it can operate continuously without downtime for maintenance.

The Western Digital Wd Red Plus 12TB is a high-performance hard drive specifically designed for use in network-attached storage (NAS) systems. The "WD120EFBX" is the model number of the product.

The hard drive has a storage capacity of 12 terabytes (TB), which is a large amount of storage space that allows you to store a large number of files, videos, music, and other data.

The hard drive has a rotation speed of 5400 RPM (revolutions per minute). This is a measure of how fast the hard drive's platters spin, and it affects the hard drive's performance. Hard drives with higher RPMs can generally read and write data faster than those with lower RPMs.

The hard drive uses the SATA-6 Gbps interface, which is a newer and faster version of the SATA interface that is commonly used in hard drives. It allows for faster data transfer speeds between the hard drive and the computer or NAS system it is connected to.

The hard drive has a buffer size of 256MB. The buffer is a small amount of memory built into the hard drive that is used to temporarily store data being read from or written to the hard drive. A larger buffer can help improve the hard drive's performance by allowing it to handle bursts of data more efficiently.

The hard drive has a 3.5 inch form factor, which is the standard size for most internal hard drives. It is designed to be installed in a 3.5 inch drive bay in a computer or NAS system.

It is optimized for use in NAS systems with up to 8 bays, which is a multiple-drive storage systems that can be connected to a network. It is designed to handle increased workloads and provide improved reliability over traditional desktop hard drives.

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.
