Data Storage Devices – Choose the Ideal Solution for Your Business
Do you need a reliable data storage device? Hard drives, SSDs, storage arrays, or NAS systems – each technology has specific applications and parameters that determine the safety and performance of your IT infrastructure. This guide is aimed at those responsible for IT infrastructure in companies and those who want to consciously choose storage solutions tailored to business needs. Discover the different types of data carriers, compare their capabilities, and find optimal solutions suited to the scale of your operations and your organisation's budget.
Business Dedicated Storage Devices
-
Solutions for small and medium enterprises
External HDDs and SSDs are excellent for creating daily backups and archiving documents. HDDs and SSDs differ in that HDDs use magnetic platters, while SSDs use flash memory.
Simple NAS systems allow for file sharing in the office without the need for advanced network infrastructure configuration.
USB drives and SD cards facilitate quick data transfer between employees and devices. Implementing such solutions means low initial costs.
-
Enterprise solutions for large organisations
A storage array with RAID support ensures high data availability through disk redundancy. SAN (Storage Area Network) systems offer block-level access to storage for critical database applications and virtualisation environments.
LTO tape libraries remain the standard for long-term archiving and provide a natural air-gap, meaning physical isolation of data from networks and computer systems, effectively protecting against hacking and malware attacks, preventing external access to archived information. Hybrid solutions combining SSDs, HDDs, and tape with cloud integration offer flexibility at optimal costs.

Specialised devices and network drives for industries
The financial sector requires storage systems with hardware encryption and the lowest latencies for transactions. The healthcare sector, on the other hand, needs solutions that meet GDPR requirements while handling large multimedia files containing patient data. Manufacturing companies require devices with increased resistance to vibrations, temperature, and industrial conditions – here, enterprise-class network drives perform best.
Which technology to choose?
Data storage devices vary in speed, capacity, access methods, and price. Choosing the right technology directly affects data read speed, system durability, and information security.
Solid State Drives (SSD)
NAND flash technology provides high performance for random read and write operations. SSDs contain no moving parts, which translates to shock resistance and lower energy consumption.
NVMe interfaces offer bandwidth significantly exceeding SATA standards – crucial for databases and critical applications. TBW (Total Bytes Written) and DWPD (Drive Writes Per Day) – a metric indicating how many times a full disk capacity can be written in a day without the risk of premature wear – define the endurance of the disk: enterprise models support many more write cycles than consumer versions.
Hard Disk Drives (HDD)
HDDs remain the optimal choice for archiving large amounts of data. CMR (Conventional Magnetic Recording) technology is used in applications requiring intensive random writes, while SMR (Shingled Magnetic Recording) offers higher capacity at a lower cost – ideal for cold storage, meaning long-term data storage that does not require frequent access.
7200 RPM models are the standard for NAS servers and archiving. 10000-15000 RPM drives with SAS interfaces are used in enterprise arrays, where access time is critical. The MTBF (Mean Time Between Failures) parameter fully defines the expected reliability – enterprise drives often claim 2-3 million hours.
RAID systems and disk arrays and their configurations
RAID 0 offers maximum performance without redundancy. RAID 1 provides mirroring – a complete copy of data. RAID 5 and RAID 6 use parity for protection against the failure of one or two disks.
Hardware RAID with a dedicated controller speeds up parity operations and supports a larger number of disks. Software RAID offers flexibility and advanced features such as snapshot creation, which allows for quick restoration of data to a previous state, and deduplication, which eliminates duplicate data to optimise storage space usage.

FAQ - Frequently Asked Questions
What is the difference between a storage array and a server?
A storage array is a specialised device solely for data storage, consisting of multiple physical hard drives connected into a single logical unit. Thanks to mechanisms such as RAID, the array offers high performance, redundancy, and data security, enabling quick access and recovery of information in case of disk failures. Arrays are dedicated to handling large volumes of data.
A server, in addition to storing data, performs various tasks such as application hosting, network management, or resource sharing with users. A server can use local disks or connected storage arrays, but its function is much broader than just data storage.
In summary, an array is a specialised data storage unit, while a server is a versatile device performing various IT functions, including access to data stored on the array or other media.
What drives should I choose for a server?
For critical applications, choose enterprise-class NVMe SSDs with high TBW. For archiving and cold storage, HDDs with CMR technology and SAS or SATA interfaces with a declared MTBF of over 1.5 million hours will be suitable.
Are SSDs suitable for NAS servers?
Yes, SSDs are excellent for NAS servers, especially in environments requiring high performance and fast data access. SSDs are often used as cache in NAS servers, significantly speeding up system performance, especially with a high number of random operations. However, due to their higher price, SSDs may be used in hybrid configurations, combining the advantages of SSDs and HDDs to optimise cost and performance.
SSDs in NAS servers are an excellent choice for companies that need a fast, reliable, and damage-resistant solution for data storage and sharing.
Is it worth investing in enterprise SSDs instead of HDDs?
Yes, if performance and low latency are priorities.
How to determine the storage capacity for a company?
Assess the current data volume, expected annual growth (averaging 20-30%), and retention policy. Add a margin of 30-40% for snapshots, backups, and system operations, considering compliance requirements for archiving.
QNAP or Synology – which NAS for a company?
QNAP often offers a better performance-to-price ratio and broader hardware expansion options. Synology stands out for its intuitive software and stability. The choice depends on priorities: greater hardware flexibility (QNAP) or ease of management (Synology).
