How to enable Readyboost that is disabled in error
My laptop came pre-installed with Windows 8.1 on a 500GB 5400RPM HDD. It has 4GB memory.
Over the holidays someone gave me a 64GB m-SATA SSD, which I put into the laptop's m-SATA slot.
On the BIOS, the info shows that the SSD occupies the SATA 0 slot. I had to re-adjust the boot order to boot normally into my system disk, which is on the SATA 1 slot.
I wanted to use the m-SATA SSD as a Readyboost cache. When I carried out the steps to enable Readyboost on the SSD, it wouldn't let me. The error message is:
This device cannot be used for ReadyBoost.
ReadyBoost is not enabled because this computer is fast enough that ReadyBoost is unlikely to provide additional benefit.
There must be some mistake because the SSD is not the system disk. It only occupies SATA slot 0 (which I cannot change). The system disk is a typical HDD.
How do I go about enabling Readyboost on the SSD? Any tweaks or commands? I have tweaked the registry many times before so if need be I could do that.
[Note: Those who want to suggest other things like sell the SSD, leave it alone, or whatever, please just heckle some other thread.]

The fact remains that he wishes to know the workaround to be able to enable Ready Boost when the operating system disables it for a device. It does not matter if you think it has no benefit. If you do not wish to or cannot give him the necessary technical know how on a workaround, then simply shut-up and do not offer any of your otherwise unneeded and unwarranted opinions on the matter. this is not an open air for your all empowering but biased wisdom. It is a problem solving venue to find answers to questions whether you yourself in your self appointed glory decide they are worthy or not of being attempted.

Simply put, if you have a SSD, your Windows installation should be on it. When it is, ReadyBoost does nothing for you. That is why the system disables it, it is telling you. Hey! Don't waste your time with this! It is like the warning label on Fireworks telling you not to point it at other people, simple intelligence but some idiots will do it anyways.
Solving a problem isn't just about answering a question, but actually addressing the issue at the core of the problem. It is like a doctor just treating the symptoms of a disease when a cure is available.
As for those who believe it won't help if you have loads of RAM, that is untrue if running a physical hard drive. The flash memory has a faster access time which matters more than the actual transfer speed of the flash memory. Even a slow SD card can still help. It basically improves SuperFetch, something having more RAM won't help you out with as one stores active applications while the other caches based on expected behavior.
