Y510p ExpressCache

The SSD caching really helps with loading commonly used apps but my boot up time is slow since I rarely reboot.

Is there a way to "staple" cache on to the SSD so that it doesn't reset?

 

No, the algorithms used for caching in IRST are made to speed up commonly used programs but not full programs just what is used most like if you play one map on a game. Depending on how large your cache is it will prioritize the boot if you restart your computer a lot. Now I I know with IRST you can erase the cache to refill it but I don't know how to prioritize anything or even if you can.

 

ISRT is not being used for caching on the Y series (or on any Lenovo laptop for that matter). Expresscache is.

 

I am not entirely positive that I understand your question but I will attempt to answer it anyway.
The contents of the cache will be saved and reloaded when you power down or reboot your system. There is a small amount of time required to repopulate the cache after a reboot or power cycle but it is not notable to the user. The cache is not reset after a reboot or power cycle.

The user does have the option to "pin" or preload applications in the cache. This is performed from the command line interface and you can contact your system supplier for the details. This will not effect the boot time but it could make the commonly used, and preloaded, apps load faster.

ExpressCache, by itself, does have a feature where it identifies the required boot blocks and aligns them on the outer most edge of the disk and provides a sequential read of these blocks. This which should enhance the boot time of the system.

Thanks..Rick

 

I got this from this guide:

Like the OP I hardly ever reboot my Y500 so my boot times are no faster than if I just had the HDD. I've noticed that the caching algorithm used by ExpressCache is very aggressive in flushing the contents of the SSD on a regular basis, especially if you launch a lot of big applications like games. The OS files don't get any priority and are flushed out just like everything else unless you do the above. 16GB or even 24GB for that matter is just too small to effectively cache many large applications as well as the OS, which is why I can't wait to get a real SSD soon.

This is the reason I like Intel Smart Response Technology better than ExpressCache: You can do these things from within the Rapid Storage Technology GUI instead of through the Windows command prompt, not to mention it supports larger cache drives (up to 64GB) and probably performs faster.

 

Ah thank you for clarifying. I always pop in an sad so never went for a cache drive.
