Cloud storage vs hard disk.

Technology trends may come and go, but cloud storage has become a mainstay for efficient data management. Instead of relying on physical drives such as local SSDs, the cloud allows users to store their data securely in remote data centers.

On the other hand, traditional storage methods, such as hard disk drives (HDDs), have been storage mainstays for decades. Through magnetic spinning disk technology, HDDs have been reliable for long-term storage.

But solid-state hard drives, or SSDs, have moved ahead in recent years as they are faster, more efficient, and boast great endurance and durability.

Cloud storage and hard drives are useful for whatever field you want to use them in, personally and professionally. However, knowing each type of storage system's advantages and disadvantages will help you discover the most useful for your business needs, remote work, or personal storage.

What are the differences between cloud storage and SSD external hard disk drives (HDD)?

To understand which storage method is suitable for your needs, first, we must get an overview of cloud storage vs hard disks, their uses, pros, cons, and, perhaps most importantly, their security features.

Once you know how each storage option works, you can decide how to store your data securely, efficiently, and safely.

What is cloud storage, and how does it work?

Cloud storage is a service that allows users to store and access their data, such as files, photos, videos, and documents, over the Internet rather than on physical storage devices, such as local hard drives.

They no longer rely solely on the storage capacity of a device, as data is stored on remote servers managed by cloud service providers. This facilitates remote access, collaboration, and automatic synchronization between devices.

Data digitization

Cloud storage revolutionizes how we store and access information by moving it from local devices to remote servers accessible via the Internet.

Users can access their files and documents from anywhere and at any time - which translates into flexibility - as long as they have an Internet connection. In addition, multiple users can work simultaneously on shared documents, eliminating the need to email files or use USB drives.

What is an SSD?

Solid State Drives (SSDs) are at the forefront of physical storage innovation. Unlike traditional hard drives, which employ spinning platters and moving heads, SSDs use NAND flash memory to store data instantaneously.

Speed is the hallmark of SSDs. With near-instant access times and fast data transfer rates, these devices transform the user experience.

This durability, combined with power efficiency and low heat generation, makes SSDs ideal for notebook users and demanding professional environments.

SSD vs. cloud storage: pros and cons

The choice between SSD hard drives and cloud storage may present a significant dilemma if you are unsure about choosing a storage solution for sensitive data. Therefore, we will explore the advantages and disadvantages of both options to help you decide what best suits your needs.

What are the advantages of using cloud storage?

The cloud is a secure and efficient storage system and is one of the most revolutionary technological advances we have seen in the current year. In 2023, the number of companies embracing cloud storage reached 94% in 2023, so it is undoubtedly the most popular storage data for companies.

Remote access

You can access your files from anywhere with an internet connection, making it easy to work remotely, especially in distributed environments. Although HDDs and SSDs can be stored either in a computer, or externally, travelling with them can put them at risk of being lost, stolen, or broken.

Automatic synchronisation

Changes made on one device are automatically reflected on all connected devices. This ensures that you always have the latest version of your files.


Cloud storage services are often scalable, which means you can increase or decrease your storage space according to your needs without changing physical hardware. Most cloud storage services have different plans to suit your space needs.

Automatic backup

Many cloud storage services offer automatic backup features, which protect your data against accidental loss or hardware failure.

Efficient collaboration

Facilitate project collaboration by allowing multiple people to work on the same documents and easily share information simultaneously. Collaborating on projects for remote companies, students, or freelancers can be one of the most crucial features for those looking for online storage.

What are the disadvantages of cloud storage?

Although cloud storage has numerous advantages, it also has some disadvantages that you should consider. However, with the right knowledge of cloud storage, you can significantly reduce its disadvantages if you follow the necessary guidelines.

Dependence on internet connection

Accessing your files in the cloud requires an online connection. In areas with limited or intermittent connectivity or poor internet speed, there may be difficulties in accessing data efficiently.

While it may be tempting to work away from home in your favorite coffee shop, accessing the cloud using public wifi includes more risks than accessing your files in public using an SSD.

Public wifi is not encrypted and is, therefore, more vulnerable. If you have no other option when accessing the cloud using public wifi, consider using a secure VPN to protect you from network attacks.

Potential security issues

Although cloud service providers implement security measures, there is always a risk of data breaches or unauthorized access. Storing sensitive information in the cloud can raise privacy and security concerns. Always have a cloud storage system that protects your data at a high level.

Limitations of free storage

Free cloud storage plans often have capacity limits, which may need to be improved for users with large amounts of data. Different companies have different free options available.

Google Drive, for example, has a generous 15GB of free storage, but considering how Google treats your data, this generous storage plan is not worth the risk if you value your privacy.

Internxt, for example, offers up to 10GB of free storage and is secured with end-to-end encryption, and your files are not stored in one centralized place, unlike Google, which is one of the most secure ways of storing your files in the cloud.

Internxt cloud storage is a privacy-focused alternative to Google.

Integration issues

Integration with some applications and systems may not be as seamless as with local hard drives. Some users may experience difficulties working with certain programs or performing specific tasks in the cloud.

Privacy and compliance concerns

In enterprise environments or environments with sensitive data, privacy and compliance concerns can arise, especially when cloud servers are in jurisdictions with different regulations.

When considering cloud storage, weighing these disadvantages against the advantages is essential to determine if it is the right choice for your specific needs.

What are the advantages of hard disk drives (HDDs)?

SSDs have several advantages, and although many people prefer to store their data online, as we have seen, cloud storage has some disadvantages. SSDs also have their advantages and can be equally as secure if you decide to store your data on them, but there are some disadvantages to this, too. Let's explore further.  

Fast read/write speed

SSDs vs. cloud storage: which is better for my business?

When considering cloud storage vs. hard disks and which is better for protecting your business data, you must evaluate several aspects of your needs and preferences.

Based on the above, here are some questions to ask yourself to make an informed decision.

Storage space

Determine how much space you need to store files or even employee data and whether you foresee significant growth in the future. Many cloud storage providers offer flexible business plans, ranging from small teams to large corporations, and some even offer the chance to self-host your cloud storage.

If you have a set amount of cloud storage, consider choosing a lifetime plan for a one-time payment. To ensure the security of your files for a lifetime, you will need an end-to-end encrypted cloud storage provider.

You can check out Internxt's pricing plans for a full breakdown of affordable monthly, annual, or lifetime storage.

Data sensitivity

Consider the nature of the information you handle. Security and physical control may be priorities when working with highly sensitive data. Whether you store data in the cloud or on hard drives, ensure that the data is protected with encryption for the highest level of security.

Access and collaboration needs

Assess whether you need to access your data from different locations or collaborate on projects in real-time. This can influence the choice between SSD and cloud storage.

For example, if you work remotely, you will need a secure way to send your files to your team so you can edit and access the most recent version of your documents efficiently.

Collaboration is less necessary if you use storage for personal use, for example, storing or sharing photos with family or friends.

Define your budget

Define your budget for storage solutions and decide whether you prefer a pay-as-you-go model (cloud storage) or a one-time investment via lifetime cloud storage or physical (SSD hard drives).

Security and Compliance

Ensure you know your industry's security and compliance requirements and check whether your option meets these standards. Businesses must take all the necessary steps to secure company and customer data.

Should the worst happen, ensure your company has the necessary response to a threat to reduce the effects of a security hack or breach.

Should you experience a cyberattack, such as ransomware, ensure you take the necessary steps to protect your accounts, such as changing the password of all your accounts, ideally using a password generator.


Assess the importance of easily scaling storage as you grow, especially if it is relevant to your business. As your business grows, you must take the necessary actions to identify risks within the company and implement access management strategies to reduce the risk of employees accessing sensitive information.

Availability and reliability

Determine the availability and reliability required for your business and consider how a service interruption would affect your business.

Backup and recovery

Investigate how data backup and recovery are handled for each option. One of the benefits cloud storage has in this case is that it backs up files frequently, so if a device is ever lost, broken, or stolen, the most recent version of the file is still stored in the cloud.

Contrary to this, SSDs are vulnerable to the same issues of theft or breaking, but if all data is stored on this device, recovering it can be considerably more difficult.

Reflect on past experiences

Reflect on past experiences with storage solutions and how they impacted your operations. Often, we learn best from previous mistakes. Still, with the right research and knowledge, businesses can learn from the mistakes of others and use this knowledge to create a cybersecurity plan that protects data.

Consult with professionals

Consider consulting with IT professionals or specialist consultants for personalized guidance. However, if you don’t have the means, time, or budget for this, there is a wealth of information available online for an overview of what to consider when storing data in the cloud or via SSDs.

Which storage option is best for personal use?

If you're considering which cloud storage is best, here are a few guidelines to help you decide.

If you handle large media files, work with demanding applications, or play games, an SSD can significantly improve the experience by offering fast read/write speeds—their durability and shock resistance benefit portability, especially if you use devices constantly on the move.

If you prioritize remote accessibility and collaboration, cloud storage is an excellent option. You can access your files from anywhere with an internet connection and easily share documents with other users.
