SanDisk Extreme 240GB SATA 3 SSD Review – Equal 4k Read/Write IOPS Performance Observed


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.

Many of the performance results are confirmed with this software and we get a good look at some great disk access times (resp. time).  There is something new here that says much for the performance of the SanDisk Extreme that is not common for other ‘SandForce Driven’ SSDs.  Normally, SSDs will either show strength in the read tests or write tests with respect to IOPS results and not both.  I think this is the first time we have seen equal strength on both sides of the fence as is evident with the read result of 72,000 IOPS and write of 74,000 IOPS. The end result is a final score of 4510 points whereas, with our recent Intel Series 520 SSD Review, the 520 reached the a score of 4130 points which is typical of most SandForce controlled SSDs.


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 pulled through Vantage testing with a high of 67617 points and a high transfer speed of 414MB/s when testing in Windows Media Center.  This placed the Extreme just below the Corsair Force GT and confirmed it to be a top tier solid state drive.  Its transfer speed of 414MB/s is uncommon in comparison to most other SSD tests.

The following chart comprises the entirety of ‘new Gen’ SATA 3 SSDs that we have testing and the placement was dependent strictly on the result attained in PCMark Vantage HDD Test Suite.
