Best 4TB Internal SATA Hard Drive That You Can Buy For Your Desktop, Server, CCTV, or NAS

Report Data Collected On: 29/Jul/2022

Hard Disk Drives are permanent data storage devices. Unlike RAM, which only temporarily stores information before it is lost when the computer is turned off or freezes up, HDDs store information even after you turn your computer off. The magnetic medium in an HDD relies on rapidly rotating discs to write and read

Even though SSDs have become popular, there are people who still prefer traditional hard drives because they can store more data than SSDs (as compared to their price ratio) and they always work exceptionally well.

If you are going to buy a new device with an HDD or if you’re thinking of upgrading your old one, it is important that you be careful in choosing the drive. You need to find a good product—and don’t take this carelessly, as they are one essential ingredient for a perfect rig!

Before buying an HDD, you should consider its form factor (or dimension), and how it relates to the device where you intend to use it. For example, are your device able to accommodate a 3.5-inch drive instead of a 2.5-Inch? How fast is data transferred from one place in memory or storage unit on the hard disk drive to another when compared with other bandwidths like SATA3 6GB/S, 7200 RPM speeds, etc?

The brand and interface of the hard drive are also important. Also, how fast the disk spins affects how quickly it can read data from a piece of media such as an optical disc or magnetic tape; therefore, you should always look for HDDs with more powerful motors when shopping around.

The third metric is latency, which measures how quickly the HDD can read sectors of information. A lower latency number indicates a higher quality drive—and better performance for sequential reads and writes. Also important are the data transfer rate (how much information per second it can pass through) and buffer memory size (the amount of data that’s waiting to be written before going back to sleep).

There is one more important thing to consider. Nowadays in the market, there is a hard disk drive that generally offers maximum storage at low costs but in my opinion, if you go for a higher capacity drive you can get better speed and storage at a very competitive price.

The 4 TB and 3.5-inch form factor variants have two variants of cache memory—128MB and 256MB, respectively; the one we are reviewing about is the 256 MB cache memory variant.

The WD’s dynamic cache technology is known for its high-speed data transfer and load. In real time, it optimizes cache between reads and writes—reducing vibration in the system, which further improves the reliability of device use.

The WD Black ‘WD4005FZBX’ has been used by gamers and PC enthusiasts since it was introduced. The hard drive has been tested and proven to be one of the best in terms of reliability and performance. This makes it perfect for storing your favorite games so that you can play them whenever you want!

With increased reliability and faster data access, the new WD hard disk drive is a significant improvement from previous models. Designed with so many good features and specifications, it delivers inspired performance. It is designed for creators—people who do things like video editing and stuff—and gamers as well.

For ZFS file systems and overall NAS system compatibility, we highly recommend WD Red Plus drives, which are optimized for higher workloads.

You can’t go wrong with this hard drive if you need something reliable for your NAS and are on a budget. However, if you are looking to run the system at full load throughout the day and night, then we recommend that you get WD Red Pro drives instead. These drives are optimized for high workloads and will give you better performance overall.

HGST’s Ultrastar DC HC310 is the best option for 4 TB drives, boasting a 2.0 million hours MTBF specification and HGST’s sixth-generation firmware updated—both of which make it well worth your consideration. The hard disk drives are designed to meet the demands of today’s data-intensive applications by offering high performance and reliability.

The hard disk drive is provided with SED (self-encrypting drives) to ensure the extreme security level, as it is about your data safety. In enabled mode, all data on a self- encryption drive will be encrypted using a private key which is inaccessible without permission from an administrator or user. This is to ensure an extreme level of data security and hence increase the trust factor of the hard disk drive.

It is faster and more efficient than other 7200 RPM drives, transferring data 20% faster while completing the process in fewer milliseconds. The time saving and efficiency make it a desirable product for many customers.

It’s not just the NSA that wants to keep your data safe. You do too. And the best way to do that is with hardware-based encryption. That’s why you’ll find HGST’s new DC HC310 hard drive equipped with this feature—to maintain the high speed of your disk, while keeping it secure!

In my Opinion;

This hard drive offers 4TB of storage, which is impressive, but it doesn’t come with any performance benefits and has a heavy price tag. You know that you can get a 6TB hard drive that offers better performance and higher storage for only about 135 dollars! Impressive right?

Happy Shopping!!!


  1. Is there any specific reason why you haven’t included WD blue 4 TB HDD in this list? Is it bad?

    I read the ratings on for this hard disk and to my surprise it’s rated only 3 stars. 30% of people have complained it to have failed on them in just couple of months…. which is honestly not expected from a company like Western Digital whose reputed for making long lasting Hard drives.

    as for Seagate, it has failed on me twice! (7200.11 and 7200.12 both) So I will never buy a Seagate HDD :/

    I am confused. I want the best 4 TB HDD for home usage on my desktop. No NAS or server usage like the ones mentioned above.

    Kindly guide me to the best 4 TB HDD to buy which will last me at least 5-10 years.

  2. You can go for Buffalo Mini-station Extreme NFC which came to the top in 2018 best hard disk. Western Digital My Passport 4 TB this will be the 2nd preference if you like WD. I will always go for WD because it is the best company that give long lasting Hard drives at low range.
