SanDisk Extreme II SSD Review (240GB) – SanDisk Finds That Sweet Spot and Hits a Home Run


You may not see this for long (and its definitely not common) but you get a freebee simply for reading! Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

SanDisk Extreme II AS SSD Anvil

Anvil confirms much of what we have seen so far which is that the SanDisk Extreme II is a rock solid SSD.  Let’s see if we can pull the IOPS right up to specs:

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


The Extreme II completed the PCMark Vantage HDD Suite with a Total Score of 74340 which is the third highest Total we have seen to date.  Not just any SSD could pit itself between the Samsung 840 Pro and OCZ Vector as we will see in our chart on the next page.

Most importantly though, the Extreme II had a top transfer speed of 429MB/s while testing in Windows Media Center and 7 of the 8 tests resulted in SATA 3 transfer speeds above 300MB/s.

      Different sites have different methods of testing. Although we look very closely at steady state number for enterprise drives, we don’t feel this is a major factor with consumers. Our test methodology was determined after abreat deal of feedback with readers.

    Look at the current this thing draws: 1.6A at 5V would require two USB 3 ports or three USB 2 ports to power it in a portable case. It is only suitable for use in cases with external power or inside a computer.
