Is Windows ReadyBoost Worth Using?
Understanding Windows ReadyBoost
When a USB flash drive is connected to a Windows computer – even older versions like Windows 8 – the operating system often prompts the user about utilizing ReadyBoost to potentially enhance system performance.
But what does ReadyBoost actually do, and can it genuinely deliver a noticeable speed improvement to your computer’s operation?
The Origins of ReadyBoost
Initially launched with Windows Vista, ReadyBoost was presented as a significant performance-enhancing feature.
However, it’s important to understand that ReadyBoost isn’t a universal solution for sluggish computers.
Limitations and Effectiveness
While it was widely advertised, ReadyBoost doesn’t function as a guaranteed fix for all performance issues.
Its benefits are typically realized only in specific, limited scenarios.
The technology is most effective when a computer has a slow mechanical hard drive and a limited amount of RAM.
How ReadyBoost Works
- ReadyBoost utilizes the flash drive as a cache to store frequently accessed files.
- This can reduce the number of times the hard drive needs to be accessed.
- By minimizing hard drive activity, ReadyBoost aims to improve responsiveness.
Essentially, it attempts to compensate for slower hardware components.
However, with the prevalence of faster SSDs (Solid State Drives) and increased RAM capacities, the impact of ReadyBoost has diminished considerably.
Modern systems often don’t experience significant gains from enabling this feature.
Understanding the Functionality of ReadyBoost
ReadyBoost operates alongside the SuperFetch feature. SuperFetch, initially released with Windows Vista, actively tracks the applications you frequently utilize. It proactively loads the necessary application files and libraries into your system’s RAM.
Consequently, launching these applications becomes quicker. Data is retrieved from the faster memory instead of the comparatively slower hard disk. Utilizing unused RAM as a cache for often-accessed applications enhances overall system responsiveness.
Typically, SuperFetch leverages your computer’s RAM for caching. However, it possesses the capability to extend its functionality to a USB drive – this is where ReadyBoost comes into play.
Enabling ReadyBoost after connecting a USB drive allows Windows to store SuperFetch data on the USB drive, thereby releasing system memory. Reading numerous small files from a USB drive is generally faster than accessing them from a traditional hard drive.
This can, in theory, lead to improvements in your computer’s performance.
The Limited Benefits of ReadyBoost
Initial assessments appear promising, however, a key limitation exists: the speed of USB storage is inherently slower than that of Random Access Memory (RAM). Storing data utilized by SuperFetch is demonstrably more efficient within your computer’s RAM rather than on a USB drive.
Consequently, ReadyBoost provides a tangible benefit only when a system is constrained by insufficient RAM. If your computer possesses an adequate amount of RAM, the performance gains offered by ReadyBoost will be negligible.
Computers with limited RAM capacity are the primary candidates for ReadyBoost. When Windows Vista launched, Anandtech conducted thorough ReadyBoost benchmarks, yielding insightful results.
Their testing revealed that, when paired with just 512 MB of RAM – a quantity considered quite small by today’s standards, where several gigabytes are common – ReadyBoost did provide a noticeable performance boost.
However, the performance improvement achieved by simply adding more RAM consistently surpassed any gains realized through ReadyBoost utilization.
Therefore, if your system is experiencing performance bottlenecks due to RAM limitations, upgrading the RAM is a far more effective solution than relying on ReadyBoost.

The Current Relevance of ReadyBoost
Despite advancements in computer hardware, ReadyBoost can still offer benefits under specific circumstances. Specifically, it may prove valuable for systems equipped with limited RAM – such as 512 MB or 1 GB – where upgrading the memory isn't feasible.
The effectiveness of ReadyBoost is directly tied to the speed of the USB drive utilized. Employing an older, slower USB stick may not yield significant performance gains, even with a modest RAM capacity.
USB Drive Speed Considerations
Windows incorporates a mechanism to prevent ReadyBoost from functioning with exceptionally slow USB flash drives. However, variations in speed still exist among USB drives, impacting the potential for performance enhancement.

Generally, ReadyBoost is unlikely to dramatically improve a computer’s overall speed. A noticeable performance boost might be observed if the system has a very small amount of RAM and a particularly fast USB drive is used, but even this outcome isn't assured.
In conclusion, while once a more prominent optimization technique, ReadyBoost’s impact is now limited to older systems with constrained resources.
