ExpressCache version 1.3.1 released

Why can’t Sandisk technical people post here?

I’m having simlar problems to the ones described in this thread.


We are lookng into this. We have an open dialog going on with Condusiv. There are many thing on this thread that are being reviewed. We will have a new release that will hopefully address ALL of your issues you have raised. No date yet… stay tuned and thanks for your input!


Hi gls ,

Nice to hear that folks at SANDISK are working hard and fast to resolve the issues.

As it happens to be, my cache ssd is rendered useless because of ExpressCache issues.

Since you are working on “ALL issues” - here are some inputs. Hope these help designing a better version.

-ExpressCache crashes computer when resuming from sleep/standby. The sleep mode is haswell’s deep sleep. Its like hybernation. Or something like that. Condusiv guys will understand… probably. 

-Experienced corrupt files with a Virtual Machine. Missing files rendered the install irrepairable. Had to reinstall.

-The drive fills up quickly when computer goes through just normal shutdown-start cycle. I am guessing its caching the same files many times over. Even though there hasn’t been any windows updates or drive defrags. Will they be able to come up with more intelligent caching methods?

Thanks to everyone who are working hard.



You mention in a post that 1.3.1 crashes your PC. Can you post the crash dump. It may help in tracking down the problem.

Hi drlucky ,

Thanks for looking into all of the issues.

I don’t have the dump files.

I have gotten rid of an application that may have caused the BSOD as well.

Right now I have EC 1.3.1 installed again. I will wait until it goes blue.

Then PM you the dump file.

Thanks again to all the folks at SANDISK and CONDUSIV.


@gls, slotmonsta, drlucky, georgealon,

Please re-read this thread and others, especially my message in this thread, #15.

When Condusiv and Sandisk *truly* work together and create a QA tested, high quality version ready for final release, I would be most appreciative. As a matter of fact, it might be better to issue a pre-release beta, for all to test, give feedback and revert back to 1.3.1 if needed, until a final “gold” release is posted.

Just how I feel. There are many threads/posts with issues.

Another idea is to build in some software telemetry that users can opt-out of, to feedback logs and other problems which can be better trapped and diagnosed by you people at Sandisk and Condusiv.

I understand that Condusiv also makes this ExpressCache software for HP’s $50 16 GB Flash Cache accelerator.

I wonder how HP is doing with the software as well.

Please make us and yourselves happy. I know it is not an easy task.

Thanks to all,

@ drlucky

After using EC for some time, I am seeing some issues more clearly.

  • PC hangs completely when resuming from sleep.

  • Event log shows “error” and “warning” numerous times for slow startup and wakeup because of EC and many drivers for other components. There are probably hundreds of these warnings that I hadn’t had any notification for. All of them relate to coming back from sleep.

  • Cache reset itself since the PC hang.

Back to square one. Can’t use EC as it is right now. What a disappointment.

TO USERS: Guys, if possible try putting your computer to standby/sleep and see what kind of reaction you get. Some of you might have the same issue.

So is your PC no longer BSOD? It would be really helpful if you can provide the memory dump after a BSOD.

Also are you still having issues with virtual machines? If so what type of VM are you using and how is it configured?

@Redcache: What virtual machine software are you using wnad how is it configured to run on your system? IS it still corrupting files or has this been fixed as well?

I am using Bitbox browser which uses VM 4.0.16. Its configured by the browser. I had one instance where the Bitbox tray app was open when computer was put to sleep and experienced missing files. Don’t remember which files. Reinstalled it and stopped using sleep/standby functin for now. I still have EC installed for last 2 days. I am seeing cache filling up too quickly. Right now its over 25gigs. It’ll reset soon.

Unfortunately I don’t have the dump files from previous BSOD to share. Wish I did. Sorry.

I haven’t experienced BSOD yet since I have stopped putting PC to sleep. Using full shutdown right now. And of course cache filling up very quickly.

Like an user had mentioned during the past day or two, if you folks want us users to beta test the whole thing then you must make it official. And also make “relatively stable” previous versions available for download. Do the whole thing.

We understand it must be difficult. But we also don’t want to see some pinhead at CONdusiv trying out his luck at a career in coding.

I am genuinely sorry to be harsh since I don’t know who would take the harshness personally.

To the folks at SANDISK, Just get it done. Good luck.

I am already checking out alternatives.There are quite a few.

BUT I won’t be leaving readycache without a detailed review on Amazon. But not just yet.

I have hope for SANDISK. I want to keep the hope alive. Its synthetic. But it still is.

And you have time… to fix it.


No need to reset the cache as once it gets full the hot-cold swapping algorithms kick in and manage the cache appropriately. The fuller, the better!

Hope you are looking at this page too…

Note the technical comments by Wetnap and myself.



Is the new version still coming out today?

I hope that they don’t release the new version until all is tested!


 What is the diffence between Sandisk Condusiv ExpressCache : Version

                                         and Lenovo Condusiv ExpressCache : Version


In Lenovo ExpressCache run smooth, no delay during boot.

In Sandisk ExpressCache run like s…

Just out of curiosity, what is the size of the caching partition on your Lenovo? Thanks.

It’s a 16GB cache drive.

Thanks for clarifying. It’s just that as I’ve explained on the 1.3.2 thread, on my system reducing cache to 16GB seemed to help a lot with stability and delays.

I’ve had briefly a Samsung ativ 5 with a 24GB Sandisk cache drive that seemed to run flawlessly, but by default the Expresscache partition wasn’t using the whole drive - I don’t remember exactly how much, but should be about 16GB too. The Intel fast boot partition was using the remaining space.

I finally got tired of using this software and the problems associated with it. I un-installed it and took the ReadyCache drive out of my computer and gave it to my son (so now he gets to deal with it, heh). I bought myself a real SSD and installed just the OS on it. A note on this, I didn’t go with Sandisk on that purchase. It’s what you get Sandisk when you don’t address and fix what needs to be fixed. Customers go elsewhere.
