    Is SSD caching working ?

    I recently bought a Lenovo Ideapad y510p with a 24gb SSD and a 1tb HDD. The HDD has the operating system and the SSD has only some drivers and Mcaffe files. I'm not sure if the SSD is caching the HDD, so i have posted a few screenshots of the eccmd.exe -info test and Disk management. The SSD is the "Lenovo" drive.

    What really confuses me is that the SSD drive is displayed in my computer. I would like to add that my HDD can't be set to Raid, so expresscache is the only option i know of. If it isn't working as intended, can someone please post the best method to get it working with expresscache.

    Apologies if I have posted in the wrong forum.

    Any help will be greatly appreciated :)

    Thanks

    Interesting setup. Most put OS on the SSD for faster loading and their data goes on the hard drive. But since that SSD is so small I guess the hard drive is best but not optimum. Sorry can't answer your exact questions.

    Try Intel Smart responce. Why can't you enable raid? Use IRST Utility.

    I always thought Lenovos didn't support Intel RST. They could only support software acceleration.

    Maybe you are correct.

    I very well could be wrong. I just remember another thread where a Lenovo user couldn't get Smart Response to install. Someone came in and explained Lenovo uses proprietary software to run its cache drives.

    Lenovo laptops do not use Intel RST. They use Condusiv Expresscache. If it is not properly installed gimme a pm i will send you the installer.

    If you need to pre-load a program on the caching SSD, type:

    eccmd.exe -preload [file/folder path here]

    For example, if you preload the C:\Windows folder to the SSD, you will get SSD-like performance for your global OS. There should then be just enough space left for your browser, music player and office suite.

    try:

    eccmd.exe -preload C:\Windows

    Everything is working as intended. You're confusing the SSD with the partition on the HDD that stores a backup of the drivers and preinstalled software. There are no visible, user-accessible files on the SSD, it is only used as a cache.

    If ExpressCache wasn't working properly, eccmd.exe -info in Command Prompt would return an error. Also, only ExpressCache software works for SSD caching in this laptop. Intel SRT doesn't work because, as you've already discovered, the chipset has no support for RAID.

    FWIW I doubt it is a chipset limitation, but rather an OROM limitation.

    There's RAID support on HM86? I thought it was only on HM87.

    Your right, my bad. I assumed the OP was able to enable RAID.

    Some of the other systems which had RAID disabled SRT through the OROM.

    I am not sure about Lenovo's implementation of the iSSD but with Samsung's express cache it does not mount it as NTFS etc.. it is not a usable drive for the OS at all. Since I have a SSD for primary in my system I had disabled the express cache and use the iSSD as a small temp drive.

    So I'd go with Jobine on this one...................

    The drive is visible in the Device Manager/Disk Management but cannot be mounted as it uses some kind of proprietary filesystem. However the contents of a caching SSD are generally very volatile, and Expresscache is known to flush itself much more abruptly than iSRT/RST. For example, if you install a Windows update, no matter how small, your cached "C:/Windows" share might have to be re-cached, which might give you a few slow startups until it gets re-cached.
