Neill Hart, Head of Enablement at CSI Ltd, gives advice for navigating the complex landscape of data storage solutions.

Data is often dubbed ‘the new oil’ due to its value, and with organisations increasingly aware of the importance of robust data management practices, concerns about effective handling is naturally growing.

This year has witnessed some of the largest data breaches on record, impacting billions of individuals and leading to an average cost of $4.45 million per incident globally. As the frequency and severity of cyberattacks rise, businesses are realising that it’s not a question of if but when they will face such threats. Consequently, establishing the right protection around data storage has become paramount in mitigating damage and ensuring operational resilience.

Storage is more than an answer to data challenges; cutting-edge operational resilience options are starting to reshape conventional wisdoms about how we think of, and deploy, storage. When operational security enters the conversation, like IBM’s latest storage strategy, storage can become more closely aligned to broader company missions ­– it’s a container for your ‘crown jewels’, a company’s most valued data, but it can intelligently secure your organisation at the same time.

Having a resilient data storage infrastructure is therefore critical, with solutions that can adapt to the evolving landscape of cyber threats while maintaining quick access to data. However, before purchasing any storage it’s important to understand the spectrum of data storage options available today and which is right for your data needs. After all, not all data storage solutions are created equal, and each offers different levels of security, accessibility, and cost.

There are various types of data storage available – from hot, warm, cold, and archived –

the key is understanding when to use them, their associated technologies, and their relative costs. It is also helpful to understand the ongoing debate between cloud and on-premises storage before determining the best fit for your organisation’s data needs.

Here, we’ll delve into the different types of storage available to help you decide whether they’re right for you.

Hot storage

Hot storage is designed for data that requires frequent and immediate access. It offers low latency and high performance, making it ideal for mission-critical applications where quick data retrieval is essential. This type of storage is typically utilised for active databases, real-time analytics, and applications that demand fast response times.

Hot storage solutions often involve solid-state drives (SSDs) or high-performance hard drives (HDDs). While the costs associated with hot storage can be significantly higher than other types of storage, the investment is justified when quick access to data can lead to improved operational efficiency and enhanced customer experiences. Businesses that rely heavily on data-driven decision-making will find that the advantages of hot storage far outweigh the costs, particularly in competitive industries where agility is key.

Warm storage

Warm storage is a middle ground between hot and cold storage, designed for data that is accessed less frequently but still requires relatively quick retrieval. This type of storage is suitable for data used in reporting, analytics, or other periodic access needs, where immediate access is not as critical as with hot storage.

Warm storage solutions often utilise a combination of HDDs and SSDs, providing a balance between performance and cost. The expenses associated with warm storage are generally lower than those of hot storage, making it an attractive option for organisations looking to manage operational costs while ensuring accessibility. Companies that handle large datasets for analysis may find that warm storage is an effective way to balance performance and affordability.

Cold storage

Cold storage is optimised for data that is rarely accessed. Although retrieval times are slower, cold storage is much more cost-effective, making it an ideal choice for archival data, backups, and information that must be retained for compliance but is not frequently needed.

Cold storage solutions typically rely on slower HDDs or tape storage systems. These options allow businesses to store vast amounts of data at a fraction of the cost of hot or warm storage. It’s important to weigh the trade-off between retrieval speed and cost when considering cold storage. It is particularly suitable for industries that require long-term data retention, such as healthcare and finance, where compliance regulations mandate the preservation of historical records.

Archived storage

Archived storage is designed for data that is almost never accessed and can tolerate longer retrieval times. This type of storage is ideal for long-term data retention, such as historical records or data that must be kept for many years.

Archived storage solutions often involve tape systems or cloud-based archival services. While these options are typically the most economical for long-term storage, they do come with the caveat of slower access speeds. Organisations need to carefully consider how frequently they will need to access archived data and whether the cost savings justify the potential delays in retrieval.

Finding the right balance between cloud and on-premises storage

Another critical decision organisations face is whether to utilise cloud storage or on-premises solutions. This choice often hinges on a balance of cost, control, and convenience.

Cloud storage offers the advantage of scalability and flexibility, allowing businesses to easily adjust their storage capacity as needs change. Additionally, cloud providers typically offer robust security measures, including encryption and regular backups. However, the ongoing costs associated with cloud storage can add up, especially if data retrieval is frequent.

On-premises storage, on the other hand, provides complete control over your data. This approach can be more secure in certain scenarios, particularly for businesses that handle sensitive information. However, it often requires a higher initial investment in hardware and maintenance costs, along with the need for in-house expertise to manage the systems.

Consider the storage needs of your customers

Designing an effective data management strategy sometimes does not only come down to considering your organisation’s requirements. Perhaps you have customers in highly regulated industries? If so, they may require you to store their data in a certain way to meet compliance. 

Ultimately, knowing which storage solution aligns to your existing needs empowers you to create a secure, efficient, and cost-effective data management strategy to enhance your organisation’s operational resilience, and that of your customers. In a world where data breaches are not just probable but inevitable, investing in the right storage solutions is a crucial move towards safeguarding your organisation’s future.
