In the world of information technology, choosing the right server drive is a fundamental aspect of renting a server. Often, when making a decision to purchase or lease a server, engineers focus on the characteristics of the processor or the amount of RAM, overlooking the importance of the optimal storage. However, it plays a key role in ensuring continuous and efficient operation of both dedicated and virtual servers.
The functional purpose of a server drive is significantly different from that of a personal computer. In a server environment, you need to store a much larger amount of data, provide constant and fast access to information, and minimize response time. Hard disk drives (HDDs), SATA SSDs, and NVMe SSDs offer different levels of performance and reliability, which is why it’s important to pay due attention to the choice of storage device.
When renting a server from a provider, the user has the opportunity to choose the type of storage device, which directly affects the rental price. In this article, we’ll take a closer look at the difference between HDD, SATA, and NVMe SSDs, and identify the areas of application where each is most effective.
Dedicated servers: HDD or SSD – comparison of characteristics
Dedicated servers are an important element of the infrastructure of many organizations and businesses, providing a reliable basis for data storage and processing. In the current range of servers provided, you can choose from 639 options with different types of drives, including HDD and SSD. These technologies have significant differences in performance and reliability, which directly affects the functionality of the server and its rental price.

HDD: traditional data storage
An HDD (Hard Disk Drive) is a traditional data storage device characterized by a large amount of memory, but a low level of performance. Compared to SSDs, HDDs have slower read and write speeds. Also, its design is less reliable. At the same time, renting a server with HDD is usually more affordable than SSD.
HDD features include:
- Interface type – SATA-III
- Average read/write speed – 100 MB/s
- Throughput — up to 100 operations per second
- Average device life – about 50,000 hours
- Maximum capacity of one disk – up to 16 TB
SSD: a modern solution for high performance
SSDs (Solid State Drives) are a more modern type of storage device that provides high speed information processing. They significantly speed up database operations and website loading, outperforming HDDs in speed. A distinctive feature of SSDs is the absence of moving parts, which makes them more reliable.
When choosing a server, including a VPS (virtual private server), you need to consider your performance requirements. For projects with a high workload and the need for speed, SSD drives are the best choice. This allows you to ensure efficient operation and satisfy users who need high performance.
Virtual servers: Comparison of SSD drives – SATA and NVMe
Virtual servers are a convenient and efficient solution for hosting web applications, databases, and other services that do not require a physical server. They are especially popular in various business models that require flexible scaling and resource optimization. When choosing a virtual server, it is important to consider the types of storage devices, as they directly affect performance, data processing speed, and storage reliability.
SSD drive interfaces
Some of the main interfaces used for SSDs are Serial Advanced Technology Attachment (SATA), Serial Attached SCSI (SAS), and Non-Volatile Memory Express (NVMe). They have their own characteristics and affect the overall performance of the server.
Comparison of SATA and NVMe
Serial ATA (SATA) technology was developed in the early 2000s to improve the performance of Parallel ATA technology, which was widely used with traditional HDDs at the time. Time passed, and with the advent of SSDs, the need for more efficient storage interfaces arose. SATA-based SSDs were introduced, providing faster read/write speeds and significant improvements in overall system performance.
SATA SSD features include:
- Interface type – SATA-III
- Average read/write speed – 500 MB/s
- Throughput – up to 100,000 operations per second
- Average device lifetime – about 1.5 million hours
- Maximum capacity of one disk – up to 4 TB
Non-Volatile Memory Express (NVMe) is a logical architectural algorithm designed specifically for SSDs. It uses the M.2 interface and the PCIe bus to provide maximum data transfer speeds. NVMe technology can significantly increase the bandwidth of storage devices, providing higher performance.
NVMe SSD features include:
- Interface type – PCI-e Gen 4.0
- Average read/write speed – 7000 MB/s
- Throughput – up to 500,000 operations per second
- Average device lifetime: about 1.5 million hours
- Maximum capacity of one disk: up to 2 TB
Selecting drives for different tasks
Choosing a server is a strategic decision that affects the efficiency and reliability of your project. Each organization has its own unique requirements, and taking them into account when selecting a server is critical. One of the key aspects of this process is analyzing the project needs with regard to the type of storage and the overall server architecture.
The variety of servers offered opens up opportunities for adaptation to different business tasks. Companies running simple websites that do not require high performance can choose a server with HDD. This allows you to optimize costs while maintaining functionality.
While for an online store where loading speeds are critical, a server with a SATA SSD is the best choice. This will ensure fast processing of requests and improve the user experience.
SaaS services and high-load projects require a more productive solution. In this case, the best choice is a server based on NVMe SSD and HDD. This will ensure reliable data storage and high request processing speed.
Databases require reliability and fast access. SATA and HDD SSDs are a good choice for these purposes, providing stable storage and accessibility to data.
A thorough analysis of project needs when selecting a drive type and server architecture is a significant step. This allows you to select the optimal solution, ensuring compliance with project requirements, scalability and high reliability. The variety of offers and technical expertise of the provider play a key role in the successful integration of the server solution into your business.
