Why Does SGN v5.40 Take 8+ Hours To Encrypt Windows 7 Devices?

Sumladar

The time it takes to encrypt Windows 7 Enterprise devices isn't looking good.  I have tried on at least 10 different newer models from Dell and Lenovo.  I've also tried it on an SSD drive (Intel X25-M) and still took 8+ hours for encryption.  Additionally the time to go from power on to the Windows desktop has now tripled.  When I tested the same devices with Windows XP with SP3 installed I experienced excellent encryption times (compared to SGE anyways) and the boot up time had an acceptable increase in of less than double.

    Hi Sumladar,

    thank you very much for submitting your experiences when using SafeGuard Enterprise.

    The increasing of the initial encryption time may be due to the intent to consume as little as possible resources in order not to “disturb” the user during initial encryption at the cost of a longer absolute time. Windows 7 offered here more possibilities to do that than previous Windows versions. We are reconsidering this approach and intend to implement further optimizations in the coming releases.

    At the moment this is the info that I can provide you with.


    Thank you very much

    Best Regards

    Dan

    Sumladar,

    I have got a Dell Latitude D630 with Windows 7 and SafeGuard 5.40 (Full Disc Encryption) and do not have any issues, it encrypted relatively swiftly and boots faster than XP previously did :-)

    I've not tried it on any other models yet but do have the E series floating around.

    Daniel I definately like what appears to be true hard drive throtling.  It is an amazing diference from SGE in which you couldnt do anything resonable until the encryption was complete.  Most of my company device builds though are done in a build depot environment by techs.  The device will not be delivered to the end client until the encryption is complete.  We have around 50,000 laptops so you can see my delema.  What was a pain of around 1 hour for build and  2.5 hours for encryption with SGE for a device now cause a build drift into two working days to complete.

    AndyB I am happy that you are experiencing excellent results.  I believe we have a D630 in the lab so I will give it a try.

    HI Sumladar,

    thank you very much for the clarification. I can totally understand your situation and will forward that info to product management. As already mentioned we expect an performance increase with the next release.

    In case that you need any support in the meantime please be so kind and open either a ticket or contact your sales contact in order to get more information about the next release if required.
