The Samsung 850 EVO is a name that holds significant weight in the realm of solid-state drives (SSDs). Renowned for its performance, reliability, and competitive pricing, it has been a top choice for both gamers and general users since its launch. But one question often lurks in the minds of potential buyers and tech enthusiasts: Does the Samsung 850 EVO have DRAM? In this article, we will dissect the technical intricacies of the Samsung 850 EVO, exploring the role of DRAM in SSD performance and whether or not this particular model is equipped with it.
Understanding What DRAM Is in SSDs
Before delving into whether the Samsung 850 EVO incorporates DRAM, it’s essential to understand what DRAM (Dynamic Random Access Memory) actually is, along with its role in SSDs.
The Role of DRAM in SSDs
DRAM serves as a cache for SSDs, significantly enhancing their performance. Unlike traditional hard disk drives (HDDs) that rely on magnetic components, SSDs utilize flash memory to store data. Here’s how DRAM fits into the picture:
Speed Advantage: DRAM is much faster than NAND flash used in SSDs, allowing data to be accessed promptly. When an SSD has DRAM, it can store frequently accessed data temporarily, which means quicker read and write times.
Wear Leveling and Garbage Collection: SSDs perform various maintenance tasks like wear leveling and garbage collection. Having DRAM allows these operations to happen more efficiently, prolonging the SSD’s lifespan.
Sustained Performance: In workloads that involve heavy and random read/write operations, the absence of DRAM can lead to significant performance drops. DRAM-less SSDs tend to slow down under such circumstances as they have limited capacity to handle data spikes.

What is DRAM and why is it important for SSDs?
DRAM, or Dynamic Random Access Memory, is a type of volatile memory that is commonly used in computing devices for temporary data storage. In the context of Solid State Drives (SSDs), DRAM plays a critical role in enhancing performance. It acts as a buffer for the data being processed, allowing for faster read and write operations. Having DRAM means that the SSD can quickly access a pool of data without needing to constantly write and read from the slower NAND flash memory, resulting in improved speed and responsiveness.
Furthermore, DRAM caching can be essential for sustained performance during heavy workloads. When an SSD lacks DRAM, it may depend on a portion of the NAND memory to simulate this function, which can lead to slower performance, especially in write-heavy scenarios. Therefore, having DRAM can significantly enhance an SSD’s performance metrics, making it a key feature to consider when evaluating storage devices.
Does the Samsung 850 EVO have DRAM?
Yes, the Samsung 850 EVO does come equipped with DRAM. Specifically, it includes a dedicated 1GB LPDDR2 DRAM cache, depending on the capacity of the drive. The presence of this cache is a significant advantage, as it facilitates the handling of various tasks that require rapid access to data, thereby optimizing both read and write speeds. This feature allows the 850 EVO to perform exceptionally well in various scenarios, from everyday tasks to more demanding applications such as gaming or video editing.
The inclusion of DRAM in the 850 EVO differentiates it from many budget SSDs that do not offer this feature. This means users can expect more consistent performance from the Samsung 850 EVO, even under heavy workloads. The DRAM cache helps maintain speed throughout usage, making it a solid choice for users who desire reliability and efficiency in their storage solutions.
How does DRAM affect the performance of the Samsung 850 EVO?
The DRAM cache in the Samsung 850 EVO significantly enhances its overall performance by reducing latency and increasing data transfer rates. With a dedicated memory cache, the SSD manages data more effectively, allowing for quicker access to frequently used files. This facilitates faster boot times for the operating system and shorter loading times for applications, leading to a smoother user experience.
In addition, the DRAM allows the 850 EVO to handle concurrent read and write operations more efficiently. For instance, in scenarios where the drive is under heavy load, the DRAM minimizes potential bottlenecks by temporarily storing incoming data, which can be written to the NAND flash memory at a more opportune time. As a result, users experience consistent performance even when performing multiple tasks simultaneously, making the Samsung 850 EVO a reliable choice for power users.
What are the drawbacks of SSDs without DRAM?
SSDs that do not include DRAM can experience several disadvantages, particularly in terms of performance. Lacking dedicated cache memory, these drives often utilize a portion of their NAND flash storage as a substitute, which is inherently slower. This can lead to significant drops in write speeds, especially during burst workloads or when filling the drive up to its capacity. Users might notice sluggish performance during tasks that require extensive file transfers or real-time processing.
Moreover, SSDs without DRAM are often more susceptible to performance degradation over time. As files are written and erased repeatedly, the absence of a dedicated caching layer can result in a less efficient management of data, leading to increased access times and overall dissatisfaction with the drive’s speed. For users who frequently deal with large files or run demanding applications, opting for a DRAM-equipped SSD like the Samsung 850 EVO can eliminate these potential frustrations.
Can the Samsung 850 EVO compete with newer SSDs?
While the Samsung 850 EVO was groundbreaking at the time of its release, it faces tough competition from newer SSD models that leverage more advanced technology and improved performance specifications. Manufacturers have developed faster NVMe protocols and M.2 form factors, which can significantly outperform older SATA-based drives like the 850 EVO in terms of speed. Thus, while the 850 EVO shows impressive performance for a SATA SSD, it may not be the ideal choice for users looking for the absolute fastest storage solutions.
However, the Samsung 850 EVO remains a solid option for many users, especially those who do not require the very latest technologies. Its DRAM cache and proven reliability make it an excellent choice for everyday computing, gaming, and general storage needs. For individuals who value cost-effectiveness and solid performance without necessarily needing cutting-edge specifications, the 850 EVO continues to hold its ground as a dependable SSD.
Is the Samsung 850 EVO a good choice for gamers?
Yes, the Samsung 850 EVO is a good choice for gamers, particularly those who play a variety of titles that do not necessarily require the latest NVMe speeds. The significant advantages of having DRAM cache contribute to fast loading times and improved overall system performance, which are essential for a smooth gaming experience. With the ability to quickly access and load game files, players will notice reduced lag and shorter wait times when launching games or moving between levels.
Additionally, the Samsung 850 EVO offers reliable endurance and longevity, which is appealing for gamers who often endure heavy usage. The firmware and management tools provided by Samsung help monitor the health of the SSD, ensuring that it remains in optimal condition throughout its lifecycle. Thus, while there may be newer alternatives on the market, the combination of performance, reliability, and value makes the Samsung 850 EVO a commendable option for gamers seeking a dependable storage solution.
