Сache retained after a reboot?

Hello!

I have a question. Accumulated cache saved after rebooting the system or not?
I for some reason after every restart the cache becomes empty and starts on a new cache. Performance gain is not noticeable.

Fresh installed win7 x64

Sorry for my bad English

it should not flush the cache after reboot. it should only flush the cache is the cache is getting out of sync. make sure that you are shutting down properly. if you are we ould need some more information. 

Download the sandisk ssd tool kit run it and post the SMART attributes. 

also go to the command prompt change directory to system32 from command prompt

cd c:\windows\system32

then run 

eccmd -info

and post the results

Turn off the computer correctly. After each turn the cache begins to fill with the new. I reinstalled the operating system, but nothing has changed.

It does not seem it is working excessively. Can you post the SMART attributes as well?

I’ve already written SMART attributes in Previous Post:

These data are derived from the program “SSD Toolkit” button "Export Data"

 

 I am not to understand why I have while working for example the value “Total Used Size”  is 1.53 GB and after reboot 793.38 MB
Why is this happening?
cache after reboot flush?

 

 

everything seems to be ok from the data. can you give us a little more info about the PC?

  1. Motherboard

  2. Storage Driver Version

  3. Encryption?

Also if you ahve not tried putting both the SSD and your HDD on different SATA ports you could try that. (Some SATA chipsets have weird issues)

  1. Gigabyte GA-P31-DS3L

  2. Microsoft 6.1.7600.16385

  3. no

The motherboard is old enough sata controller without support AHCI.
Maybe it makes sense to try the external pci-e sata controller installed?

is your HDD IDE or SATA?

i beleive that board uses the Intel ICH7 storage controller which should support AHCI. TRIM does not work in IDE mode so if possible I would suggest changing BIOS to AHCI and reinstalling the readycache SSD. 

my HDD IDE

this board not support RAID/AHCI mode despite the fact that a ICH7.

BIOS is the latest

there are any other options?

Does the same issue occur after waking from sleep and hibernation? 

after sleep and hibernation, all OK!

now test it on another motherboard with the Southbridge ICH10R
how will test write later

So, I tested on another motherboard with ICH9 southbridge, the situation is exactly the same as before.

Mode in the BIOS is AHCI.

OS fresh reinstall.

What other suggestions?
One gets the impression that this is a bug in the software

The contents of the cache, which is a listing of LBAs, will change after reboot, shutdown or during an idle state. The software is constantly editing, checking and changing those LBAs in the cache that are no longer relevant - this is a continuing maintenance on the cache. Factors that are considered when data is expelled range from time (how long has the LBA been in the cache without access to the LBA) to the number of times the LBA has been accessed. The more times the LBA is accessed, the longer it will remain in the cache and the “harder” it will be to expel that LBA.

I am now seeing the same thing on Win8.  With the very same hardware, it was working with Win7.  I upgraded to Win8 Pro and reinstalled it.  Now it doesn’t maintain the cache through reboots.  It also flushes the cache randomly.  Is there an error log?

I’m experiencing the same problem on Windows 8 too. Seems the software isn’t quite up to snuff yet.

same Problem here, win8, how could a Software Speed up booting if its not even autostarted ? have 2 start it manually, Cache is empty, startin on 0, and there is absolutely NO acceleration, NO effect 2 the System at all, i really should get my Money back 4 this disappointment ruined my xmas, cause even investing 50€ into 50 bottles of wine would give me much, much more than this bs, so “pls” has sandisk anything 2 say about this ? I HEAR

I uninstalled the software and did a fresh install. It is holding the cache now, however booting up is still slow.

The first few times I start my computer window’s booting is sped up. Then its like the software forgets the start up files or something, and I’m back to a slow booting windows.

is there a way 2 get the prog 2 autostart, when it obviously doesnt ?

the service autostarts. the GUI does not need to be open for the EC service to be running. If you open task manager and go to the services tab you will see Expresscache is running. the GUI is just a visual aid and not actually needed.
