Product Description of Western Digital 0F19448

0F19448 is a Western Digital Ultrastar 7K4000 internal hard drive with a storage capacity of 4TB. This hard drive is designed for enterprise use and features a high spindle speed of 7.2K RPM, a 6Gbps SATA interface, and a large 64MB buffer. In this article, we will explain in detail the features and benefits of this hard drive, and how it can be used in enterprise applications.

High Storage Capacity

The Western Digital Ultrastar 7K4000 4TB hard drive is an ideal solution for enterprise applications that require a high storage capacity. With a massive 4TB of storage space, this hard drive can store a large amount of data, including applications, files, and documents. This makes it a great choice for businesses that need to store large amounts of data, such as media and entertainment companies, financial institutions, and healthcare organizations.

High Spindle Speed

The Western Digital Ultrastar 7K4000 4TB hard drive features a high spindle speed of 7.2K RPM. This means that the drive can read and write data quickly, making it a great choice for applications that require fast data access, such as online transaction processing, data warehousing, and file serving. The high spindle speed also reduces the latency of the drive, which means that it can access data faster and with less delay, leading to improved application performance.

6Gbps SATA Interface

The Western Digital Ultrastar 7K4000 4TB hard drive uses a 6Gbps SATA interface, which provides fast data transfer rates between the drive and the computer's motherboard. This allows data to be transferred quickly, which is essential for enterprise applications that require fast data access. The 6Gbps SATA interface is also backwards compatible with older SATA interfaces, so the drive can be used with older computers and servers.

Large 64MB Buffer

The Western Digital Ultrastar 7K4000 4TB hard drive has a large 64MB buffer. The buffer is used to store frequently accessed data, which can be accessed quickly by the drive. This helps to improve the drive's performance and reduce the amount of time it takes to access data. The large buffer also helps to reduce the amount of wear and tear on the drive, as frequently accessed data can be stored in the buffer rather than being read from the disk.

RAID Support

The Western Digital Ultrastar 7K4000 4TB hard drive is compatible with RAID configurations. RAID (Redundant Array of Inexpensive Disks) is a way of combining multiple hard drives into a single logical unit for the purposes of data redundancy, performance improvement, or both. RAID can provide increased performance by spreading data across multiple drives, and can also provide data redundancy by storing multiple copies of data on different drives. This makes the Western Digital Ultrastar 7K4000 4TB hard drive a great choice for businesses that require data redundancy and high performance.

Enterprise-Class Reliability

The Western Digital Ultrastar 7K4000 4TB hard drive is designed for enterprise-class reliability. It features a Mean Time Between Failure (MTBF) of 2 million hours, which means that the drive is expected to last for a long time. It also has a rotational vibration sensor, which helps to protect the drive from damage caused by vibrations. The Western Digital Ultrastar 7K4000 4TB hard drive is also designed to be power-efficient, which helps to reduce the overall cost of ownership.

Overall, the Western Digital Ultrastar 7K4000 4TB hard drive is an excellent choice for enterprise applications that require a high storage capacity, fast data access.

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.
