It is almost impossible for your phones and PCs to match the storage capacity of external hard drives. That’s why we need them. In my case, I love bigger storage numbers that take start from TBs instead of GBs.
I was planning to have storage where all my data is stored in one place and all of my devices can share. During research to find the perfect drive for my purpose, I made a list of hard drives that are designed to serve bigger storage needs.
This is a list of the largest hard drives that are available in the market currently. You might need them for business purposes, a library, or if you are like me who is just too passionate about collecting every movie, TV series, and music video that you come across.

From my point of view, Seagate is the most known name in the data storage devices market. I was excited to discover that this is a high-capacity hard drive optimized for NAS (Network Attached Storage) enclosures, to serve my purpose. There is no chance of losing the data and performance is at its peak almost every time.
I think it is perfect for home as well as small and medium businesses. These drives are also available in smaller sizes —10TB, 8TB, 6TB, 4TB, 3TB, 2TB, and 1 TB.

With its 14 TB size, I think you can store almost all the data that you want to keep and take wherever you want. I have found for hardware connectivity, there are 3 ports with two of them being Thunderbolt 3 and one being USB.
The high-speed data transfer allows you to transfer data up to 250MBps. After comparing all the specifications carefully I found this is also the largest hard drive compatible with macOS and Windows.

This is the same hard drive as the 1st one with a smaller size. It also has the IronWolf health management that improves your system’s reliability by displaying prevention, intervention, and recovery options for the user. These hard drives are best used in Network Attached Storage (NAS). I’d recommend using this drive with 1 t0 8 bay NAS system.

This is another big and portable hard drive from G-technology. It has other versions too like 8TB, 6TB, and 4TB. I’d recommend this for ruff and tuff uses as this superfast 10TB enterprise-class 7200 rpm hard drive comes with an aluminum case so it is much more durable.

As I have found, this one is currently one of the most-rated internal hard drives with really good reviews on Amazon. I think this is best suited to be used in NAS systems with up to 8 bays. The drive is very durable and comes with a 3-year warranty.

I think this is the best 8TB external hard drive available in the market. It is also available in 10 TB size. As I have found it comes with WD Backup software for Windows and Apple time machines which will auto backup all your photos, videos, music, and documents. The drive also has password protection with hardware encryption. It has a good design and is completely reliable in terms of durability and shock tolerance.

Toshiba X300 hard drive is specially designed for gamers. I’d recommend it for heavy pro users due to the 7200 RPM speed with a 128 MB cache that gives an extreme performance. From my point of view, Toshiba is surely a reliable brand. This huge hard drive comes with high storage density and data protection technology.

Conclusion
I think these are some of the largest hard drives with maximum internal and external capacity currently available. With these devices, you can store not just your data but your friends’ data too.
As I wanted to have my data centralized, I decided to use the Seagate 12 TB IronWolf inside a NAS enclosure. I’d recommend you go with the one which is compatible with your device and comes under a suitable budget for you.
