UD5 vs UD4.7


benchtestresultsI don’t look at the Knowledge Base on www.revelation.com enough and I’m often surprised at the information that resides there.  Today was no exception and just proves how long it was since I took a look and how important it is to check there fore time to time.

I have been talking to a few people about the UD5 and the upgrade process from earlier versions of the Universal Driver and the benefits of the upgrade and performance ‘always’ comes up.  I was therefore pleasantly surprised to see that Revelation have recently published some bench test results which compare the Universal Driver 4.7 to the Universal Driver 5.0, running both with and without encryption.

There are four tests which were completed using all three configurations (UD4.7 without encryption, UD 5.0 without encryption and UD 5.0 with encryption).  The results are nicely summarised in a graphic and there are also detailed screen shots of the results screens and the parameters used for each of the tests – totally transparent reporting.

I’ll leave you to review the knowledge base article, but it was good to see that the UD 5.0 is consistently faster than the UD4.7 when running without encryption. 

Running with encryption sees a decrease in performance of around 2 to 2.5 times the time taken in the UD 4.7 without encryption.Which is expected for obvious reasons.

Please see www.revsoft.co.uk for more details about the Universal Driver or contact your local Revelation representative or application author to discuss your upgrade to the UD5.

  1. Martyn, I think an edit of the following paragraph is needed:

    “Running with encryption sees an increase in performance (which is expected for obvious reasons) with an decrease in performance of between 85% and 175%, so not as much of a hit on performance as some users have suggested to me.”

    The word “increase” should be “decrease”, correct?
