More Information about the Hard Drive

In the world of digital technology, data storage is a crucial element. The Hitachi HDS723020BLA642 Deskstar 2TB SATA Hard Drive is a popular choice for those seeking reliable and high-capacity storage solutions. In this comprehensive guide, we will delve into the various aspects of this hard drive, breaking down its specifications and features, and explaining its significance in simple terms.

Understanding the Basics

Before we dive into the specifics of the Hitachi HDS723020BLA642 Deskstar, let's understand the key components of its name and what they means.

  • Hitachi HDS723020BLA642: This is the model name of the hard drive, identifying it within the Hitachi Deskstar series.
  • 2 Terabytes (2TB): This indicates the storage capacity of the hard drive, which is a whopping 2 terabytes, or 2,000 gigabytes. This is essential for storing a large amount of data, including documents, photos, videos, and more.
  • 7200 Revolutions Per Minute (RPM): The hard drive's speed is measured in RPM, and this one operates at 7200 RPM. The higher the RPM, the faster the data can be accessed and transferred.
  • Serial Advanced Technology Attachment (SATA): This is the type of interface used to connect the hard drive to a computer. SATA is widely used for its reliability and speed.
  • 6 Gigabits Per Second (GBPS): The SATA interface operates at 6 GBPS, indicating the rate at which data can be transferred between the hard drive and the computer.
  • 64 Megabytes (MB) Buffer: The buffer, also known as the cache, stores frequently accessed data for quicker retrieval. In this case, the hard drive has a 64MB buffer, enhancing its performance.
  • 3.5-Inch Internal Hard Disk Drive: This refers to the physical size and form factor of the hard drive, which is designed to fit into standard desktop computer cases.
2TB Capacity: The Power of Storage

The Hitachi HDS723020BLA642 Deskstar boasts a remarkable 2 terabytes of storage capacity. To put this into perspective, 2TB is equivalent to around 2,000,000 megabytes or 2,000 gigabytes. This massive storage capacity is ideal for a wide range of applications, from storing large media libraries to acting as a reliable backup solution for your important files.

  • Media Storage: With 2TB, you can store thousands of high-definition movies, tens of thousands of songs, or countless photos without worrying about running out of space.
  • Data Backup: If you need to back up your computer's data, whether it's for personal or professional use, this hard drive offers plenty of room for all your important files and documents.
  • Gaming: Gamers will appreciate the ample storage for their game libraries, as modern games often require substantial storage space.
  • Multimedia Editing: If you're into video editing or content creation, a 2TB hard drive provides the capacity needed for working with large video files and other multimedia content.
Speed Matters: 7200 RPM Explained

The Hitachi HDS723020BLA642 operates at a speed of 7200 revolutions per minute (RPM). But what does this RPM value mean, and why is it significant?

  • Data Access Speed: RPM refers to how fast the hard drive's platters spin. In simple terms, the higher the RPM, the quicker the hard drive can read and write data. This is crucial for tasks that involve opening files, launching applications, and booting up your operating system. A 7200 RPM drive is considered a standard for desktop computers and provides a good balance between speed and reliability.
  • Multitasking: The 7200 RPM speed is particularly beneficial for multitasking. If you're running multiple applications or accessing various files simultaneously, a faster RPM helps maintain smooth performance.
  • Gaming Performance: Gamers often prefer hard drives with higher RPM values because they reduce loading times and improve in-game performance.
  • Media Playback: For tasks like streaming high-definition video or audio, a 7200 RPM drive ensures seamless playback without stuttering or buffering.
SATA Technology: The 6GBPS Connection

The Hitachi HDS723020BLA642 Deskstar employs Serial Advanced Technology Attachment (SATA) technology, with a data transfer rate of 6 gigabits per second (GBPS). Let's break down what this means:

  • SATA Interface: SATA is a widely used interface for connecting storage devices, such as hard drives and solid-state drives, to computers. It's known for its simplicity and reliability.
  • 6 GBPS Speed: The 6 GBPS speed indicates how fast data can be transferred between the hard drive and the computer. In simple terms, this ensures that data moves quickly and efficiently, reducing waiting times when copying or accessing files.
  • Compatibility: SATA is a standard connection found in most desktop computers, so the Hitachi HDS723020BLA642 Deskstar is compatible with a wide range of systems.
  • Future-Proofing: SATA technology is still relevant and widely used, making the hard drive a reliable choice for the foreseeable future.
Boosting Performance with a 64MB Buffer

The hard drive is equipped with a 64MB buffer, also known as a cache. This buffer plays a crucial role in improving the overall performance of the drive:

  • Data Acceleration: The buffer acts as a high-speed storage area for frequently accessed data. This means that when you open a file or run an application, the hard drive can retrieve the required data from the cache, which is much faster than accessing it directly from the disk. This results in quicker load times for applications and files.
  • Smooth Multitasking: If you're multitasking or running several applications simultaneously, the buffer can reduce lag and improve system responsiveness by holding frequently used data at the ready.
  • Optimized Performance: Whether you're browsing the web, working on documents, or gaming, the 64MB buffer ensures that your hard drive performs efficiently, even when under heavy load.

The performance of the Hitachi HDS723020BLA642 hard drive will depend on a number of factors, including the device it is installed in, the workload it is subjected to, and the type of data being accessed. In general, hard drives with a higher spindle speed and larger buffer size may offer improved performance, but other factors such as the interface and the drive's firmware can also affect its performance.

In terms of specific performance metrics, the Hard Drive has a sustained transfer rate of up to 210 MB/s (megabytes per second) and an average seek time of 8.9 milliseconds. These numbers are just rough estimates and may vary depending on the specific use case.

It is worth noting that hard drives are generally slower than solid-state drives (SSDs) and may not be the best choice for applications that require high input/output operations per second (IOPS). SSDs are generally faster than hard drives and can offer improved performance in certain workloads, but they tend to be more expensive on a per-gigabyte basis.


The Hitachi HDS723020BLA642 is a 2 TB hard drive with a spindle speed of 7200 RPM. It uses the SATA interface with a data transfer rate of 6 Gbps (gigabits per second).

In terms of compatibility, the Hard Drive should be compatible with any device that supports the SATA interface and has a spare 3.5-inch drive bay. You should check the manufacturer's documentation for your device to confirm that it is compatible with 3.5-inch hard drives and has a free drive bay available. You should also check that the hard drive's power and data cables are compatible with your device.
