Samsung's RAM Plus Feature Consumes Storage Without Significant Performance Gains
Virtual memory allocation on Galaxy devices often sacrifices storage space for negligible multitasking benefits.
1The Hidden Storage Cost
Samsung devices frequently enable RAM Plus by default, allocating significant portions of internal storage as virtual memory. On a Galaxy S26 Ultra, this feature can claim 8GB of space. While intended to assist multitasking, users often find this allocation unnecessary, especially when the device already possesses ample physical LPDDR5 or LPDDR5X RAM.
2Technical Limitations of Virtualization
Virtual RAM relies on UFS 3.1 or UFS 4.0 flash storage, which inherently possesses higher latency and lower bandwidth than dedicated physical RAM. Because Android already utilizes zRAM to compress data within physical memory, RAM Plus often acts as redundant overflow storage rather than a genuine performance upgrade for demanding applications or gaming.
3Samsung's Official Performance Caveats
Samsung documentation clarifies that virtual memory does not guarantee improved performance or increased background app availability. The company acknowledges that this storage-based memory is significantly slower than physical hardware. Consequently, the feature serves more as a marketing tool for entry-level devices than a functional necessity for high-end flagship smartphones with large RAM capacities.
4When Disabling Is Recommended
For users with flagship devices like the S-series or Z Fold/Flip models, disabling RAM Plus is often beneficial. Since these phones typically feature 8GB or more of physical RAM, the virtual allocation provides no tangible advantage. Reclaiming this storage space allows users to store more photos, videos, and applications without compromising system stability.
5Exceptions for Low-End Devices
Disabling RAM Plus is not advisable for all users. Devices equipped with only 3GB or 4GB of physical RAM face significant memory pressure from modern Android services. In these specific cases, virtual memory can prevent aggressive app closures, helping maintain a smoother user experience when switching between multiple background tasks and system processes.
6How to Reclaim Storage
Users can manage this setting by navigating to Settings, selecting Device Care, and tapping the Memory menu. Within the RAM Plus section, a toggle allows for complete deactivation. A system restart is required to finalize the change, effectively freeing up the previously reserved gigabytes for personal files and essential app data.
7Evolution of Control Options
Samsung introduced the ability to fully disable RAM Plus starting with the One UI 5.0 update. Prior to this, users were often restricted to reducing the allocation to a minimum of 2GB. This shift reflects a growing recognition that users prefer granular control over their device resources rather than automated, one-size-fits-all memory management.
8Strategic Resource Management
Ultimately, the trade-off between virtual memory and internal storage capacity remains a critical consideration for power users. While RAM Plus offers a safety net for entry-level hardware, it remains largely superfluous for modern flagships. Prioritizing physical storage over unused virtual memory ensures that high-speed flash memory remains available for actual user content.
