L540 with M.2 SSD & Windows 8.1 - ExpressCache or RapidBoot?

2014-07-24, 18:41 PM

Hello everyone. I just got a new L540 that I ordered with the M.2 16GB SSD add-on to improve performance. I noticed that my system is taking shall we say, non-SSD times to boot up and I can hear it largely reading from the mechanical HDD when starting. After doing some research, I'm not sure if the factory image was properly configured for the M.2 drive. I've seen a lot of people talking about ExpressCache which is not installed here. It only lists the L530 among its supported devices but I presume the L540 would be supported too. I do have RapidBoot HDD Accelerator installed but it's not only showing at 32-bit (I have 64-bit Windows 8.1) but that software isn't even available as a download on my model's drivers page. I have a feeling the wrong software was installed and the M.2 SSD is not being used. Can someone please confirm for me if I should be using ExpressCache or RapidBoot for this model and where the latest version of that can be obtained? Also, is there an easy way to verify the presence of the M.2 SSD in the system? It's on my invoice, I know I'm supposed to have it but it doesn't appear to be working. Thanks all!

Solved! See the solution

To confirm whether the 16GB cache driver is present or not, run "diskmgmt.msc"   (just type this into the start screen).

 

Disk Management will load and will show you a GUI representation of the disks that are installed in your system.

You should see "Disk 0" which is the size of your HDD, and then you should see "Disk 1" which is ~16GB.  Do you see this?

Good call. The drive is definitely present in the machine. I used to have an (admittedly larger) SSD cache solution in my gaming desktop though and it definitely doesn't feel like it's being utilised on this machine. It's confusing given that I can't find a download for RapidBoot or ExpressCache on the L540 downloads page and the RapidBoot version that came pre-installed is 32-bit. Does anyone know which of these software tools I should be using with this model?

So "ExpressCache" is not listed in Control Panel -> Programs and Features?

 

If it's not installed, the download you need is here:

It's seems to be a clerical error that your system (L540) was accidently omitted from the supported systems list.

Also that a 32-bit edition of RapidBoot was installed instead. :) I will grab ExpressCache shortly and try it out. Thanks.

OK so this is very odd. ExpressCache did not show up in Programs and Features but when I downloaded it and ran the installer, it asked if I wanted to uninstall. I did so and reinstalled it and now it appears in Programs and Features. I'll see if this makes any difference in performance. Should RapidBoot HDD Accelerator (32-bit) be installed alongside it or should I remove that?

My personal opinion is that RapidBoot HDD Accelerator has no value, and in fact the software recently went end-of-life so it won't be shipping on upcoming models.  I do not run it on my own systems.

 

ExpressCache is a learning cache so it takes some time for the cache to fill up with your most frequently used files.  You can check the efficiency of the cache by opening a command prompt as administrator and then enter the command "eccmd.exe -info".  At the bottom of the output should be percentages for cache read and write.  The higher the percentages, the better, and it means that the cache is working well.

This helped me too

Awesome, thank you for your help! I'll uninstall RapidBoot. That it's EOL is reason enough but yeah, it seems llike it would conflict and get in the way of ExpressCache. The percentages for EC are low right now cause I just reinstalled it but they're not 0% so it does appear to be working. I'll keep my eye on it. Thanks very much!
