How Much Data Can 4TB Hard Drive Hold?

Posted on March 21, 2022Comments Off on How Much Data Can 4TB Hard Drive Hold?

The first time I heard of the word terabyte, I was using an ancient HP laptop with 120GB and I had dozens of movies on it and still a lot of space to spare. I wondered what I would be needing one terabyte of data storage for? One terabyte would be nine times what I already had and couldn’t finish. I would never exhaust one terabyte of data, I decided. I would never even go halfway. Even when 500 GB laptops became the norm, I only upgraded because of the more modern software and systems and not because of space.

One day, I had cause to drop by at the media room of my church to collect a message I really liked and the tech guy there asked me which date was the message I was looking for preached and it occurred to me that they could have data heading back to 1994. The blindfold dropped and I saw clearly that there are people who would exhaust 1 terabyte of storage within days and who 4TB hard drive would be an average storing space and not the bottomless ditch I would have ascribed to it.

How much data can 4TB hard drive hold?

A lot. That is if you are a non-tech person, and you must be, wondering, to wonder this.

A bit is a tiny unit of digital information. 8 bites make one byte. 1,024 bytes make one kilobyte (KB). 1,024 kilobytes make one megabyte (MB). 1,024 megabytes make one gigabyte (GB). 1,024 gigabytes make one terabyte (TB). 1,024 terabytes make one petabyte (PB). 1,024 petabytes make one exabyte (EB). World without end.

Let’s look at how much data using photo, video, and audio files to judge how much data there can be in a 4TB hard drive.


Digital image sizes depend on the format, resolution, model, MP, editing, etc. involved.  An image can be as small as 20KB. An image can be 200KB. If this is the case, 4TB will contain 20,971,420 images. A 3MB photo will require 1,398,100 of its kind to fill up 4TB.

Is your password too easy?

The lowest professional shooting megapixel is 4. 4 MPs images average of 12 MB each, which will be 2928000 images in 4TBs.

One of the highest MPs is 22 and it produces images of up to 66MB for each. This will amount to 532000 images in 4 terabytes.


Pirated movies usually come in 300MB. With a 4TB hard drive, you can collect about 13,400 such videos.

A superquality pirated copy of this video can be as high as 700MB which means you can have up to 5,750 of such video files in your 4TB storage.

1080p Full HD movies come at 3.5GB for each. About 1,170 of them would fit into your 4-terabytic storage system.

A DVD contains 4.7 GB which means you can gather videos in 871 DVDs to fill 4TB.

One Blu-ray disc contains 25 GB. You will need 160 Blu-ray discs to fill your hard drive measured at 4 terabytes.

4K Ultra HD/ 2160p movies come in about 100GB for one. If you own a 4TB hard drive, it can hold about 40 movies.

8K movies are approximately 200GB in size and your 4TB will carry just 16 of them.


Audio can be measured in kilobits per second which is abbreviated as kbps. So, you will see lines such as 128 kbps or 198 kbps. This is not to be confused with kBps which stands for kilobytes per second. 1 kBps is equal to 8 kilobits just as above, I mentioned above that 8 bits make one byte. There are times you will see Mbps but sounds are mostly measured in bits, so you will see kbps most of the time.

A four-minute song at 128 kbps will come to you in about 5MB. In a 4TB hard drive, there will be room for approximately 838,000 songs.

An album is defined to contain at least 25 (in some cases 30 minutes) and has at least five tracks. So a five-track album, sometimes referred to as EP (extended play).

An eight-song album of about 40MB worth of data will see about 100,000 albums in a 4 terabyte storing capacity. A ten-song album that amounts to approximately 50MB will see your 4TB carry as much as 80,000 albums.

An album containing twelve songs recorded at a data of 60MB would see about 67,000 albums contained in a four-terabyte storing system.

The average length of a podcast, according to, is 43 minutes. At 128 kbps, every minute would carry 1.25MB. The average podcast would carry 54MB meaning that if you are into podcasts, you can store up to 74,000 podcasts in a 4TB drive.

A CD contains about 650MB which means you can have about 6,452 of them in your 4TB. Mind you, one GB can only carry one CD since you can’t put half a CD in the remaining 374MB left in the GB, so the remaining space is useless for another CD. There are over 4000 GB in a 4TB space and they can hold over 6,400 CDs but if you were to have 4092 GB in one GB units, they would only carry 4092 CDs.
