What Is 4K Hard Drive (HDD/SSD)

Before you understand what 4K Hard Drive is, you need to know the hard drive storage sectors.

Hard Drive Storage Sectors

The hard drives stores data on one of its allocated sectors. There is more than one sector on your hard drive. They are entirely different than your storage space.

Each hard drive sector is meant to store a fixed amount of data that you can access and use. In simple terms, every single piece of information of your digital device is stored on these different hard drive sectors.

4K Hard Drives

The traditional hard drives have a sector space of 512 bytes. But with advancements in technology, hard drive manufacturers are opting for a higher 4096-byte sector space, also known as 4K or 4KB sectors hard drives.

Moreover, these new 4K hard drives have higher storage density and are much more reliable. But, the decision to go for these 4K hard drives comes with some trade-offs. Read the following section to see if you should go for a 4K hard drive or not.

Do You Need to Transite to 4K Hard Drive?

Since 4K hard drives are new, people are thinking of shifting to them for better storage sectors. The majority of hard drives are currently using the 512-byte sectors format. However, a 4K hard drive has specific pros and cons. Let’s see them below.


1. Hard Disk Space Usage

The hard drive sectors store your actual usage data. But, the sectors have gaps between them. The higher the storage space, the more gaps are on a traditional 512-byte hard drive.

Therefore, the 4K hard drives are meant to reduce the gaps between the hard drive sectors. By reducing the gaps, your hard disk space can be better utilized. Not just does it help to improve the hard drive space, but it also enhances your hard drive performance.

2. Format Efficiency

The 4K hard drive format is much more efficient than the traditional 512-byte hard drive. It eliminates all the repeated data headers between sectors. Apart from that, they improve excellent performance when the sectors have less redundant data.

3. Error Correction

The 4K hard drives support higher integration of the error correction algorithms. The error correction sectors help to correct problems related to your hard drive’s sectors. Thats why 4K hard drives can incorporate them in larger quantities than possible in a 512-byte hard drive.


1. Compatibility Issues

The 512-byte hard drive is older, and most operating systems and hardware architectures support them. Contrary to that, 4K hard drives are new and lack support.

Moreover, most operating systems will have compatibility issues with your 4K hard drive. There will also be problems with your system’s architecture to support them.

2. Unsupported Scenarios

Also, even if your operating system supports it and your system architecture works with it, you can still face unsupported scenarios. It primarily includes the application level failures where your applications fail to work with a 4K hard drive.

How Do I Know if My HDD is 4K?

You can check if your system currently has a 4K HDD or not. Checking that gives you a better idea about your hard drive.

Follow the below steps to know if you are using 4K HDD:

Steps for Windows Vista and Windows 7 Operating System

Step 1: Click the Start button from Taskbar and open Run. In the Run window pop-up, input "msinfo32" and hit the Enter key.

Step 2: Once the System Information window is visible, move to Components > Storage > Disks.

Step 3: Read the Partition Starting Offset value and see if it is disabled by 4096.

If the Partition Starting Offset value is disabled by 4096, your hard drive is 4K.

Steps for other Windows Operating Systems

Step 1: Open the CMD.

Step 2: Type the diskpart and hit enter.

Step 3: Enter list disk and hit enter again.

Step 4: Enter select disk 0  and then enter list partition.

Read the Offset alignment. If it is divisible by 4096, then your HDD is 4k.
