JMicron SSD Testing With A19, L85A & L85C Memory


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance.  For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs.  Pay close attention as many might mistake the high scores for a RAID result; they are representative of the AS SSD Total Score.

Perhaps the most surprising results with AS SSD were the Total Scores of 1002 for the Toshiba A19 memory, and 957 for the IMFT L85A memory.  These are very strong results and weren’t really expected for the JMicron JMF667H controller.


This IOPS chart might be a bit confusing if you are not familiar with AS SSD< however we wanted to display the different IOPS measurements for these three sample SSDs.  JMicron has done some great work with the Toshiba A19 memory and this is probably a very positive indication of the quality that Toshiba Toggle Mode memory is.


The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as XBox
  • Cataloging a music library
  • Starting applications

Toshiba completed PCMark Vantage testing with an amazing high score of 71293 and high transfer speed of 412MB/s while testing in Media Center.  Even more encouraging was the fact that 6 of the 8 tests attained SATA 3 transfer speeds.  Bothe IMFT L85A and L85C samples resulted in very similar high scores of 66960 and 66969, consecutively.  This chart displays individual results for the battery of tests:

    Jmicron has really come a long way. Their newer lineup is pretty decent. Lets just hope that their pci-e solutions come out good and that lots of partners use it.

    Although one thing will always be mind-boggling…. How the hell did JM602 ever came to market ? I mean, didn’t they validate it ?!

      It was one of the first…everyone was amaze at this new technology. Before they could breath they had sales from most companies trying to get in on this new technology… It was literally an overnight thing.

      Qw forget that they weren’y alone . This just stuck with them because they had so many manufacturers who had purchased the controller.
