Corsair Force GT SATA 3 240GB SSD Review – This GT Is Some Force To Reckon With!


Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.  The following results will show 0Fill data (compressible) on the left with random data sample results (incompressible) on the right.

blankWe typically see lower high sequential performance results when comparing our Crystal scores to that of ATTO.  Two things that do stand out are the decent high sequential write result of 303MB/s (when testing highly incompressible data) as well as the 4k random write score of 97MB/s.

When comparing the performance difference from a hard drive to a SSD, the visible upgrade we see is mainly the result of the absolutely incredible access time of the SSD which is typically 90 times faster. Next in line, however, is the all important low 4k random write disk access which executes countless small 4k files to start your OS and applications.


Up until recently, ATTO was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the worst case scenario in SSD transfer speeds while using SandForce Driven SSDs as they use compression in storage as discussed earlier.  Many enthusiasts like to AS SSD for their needs.  Lets see how the AS SSD result compares to that of Crystal ‘random’ above on the right:

blankblankAS SSD results seem to deviate from that of Crystal with random data sampling as a result of the way the different tests are performed.  In our Crystal DiskMark tests, three tests are performed and the highest result of the three is posted.  This isn’t the case with AS SSD, however, as it calculates the average of the three tests for its final score.

You may also notice that we provided the AS SSD IOPS result on the right.  A bit outstanding are the 4k-64Thrd results which are above 54,000 IOPS for both read and write tests.


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.  Recently, we published the exclusive public release here and, if you happen to check it out, there is a FREE download of the software!  Lets see how the Corsair Force GT SATA 3 240GB SSD fares on the Anvil Pro:

blankFor those new to Anvil Pro, the system in use is visible on the bottom left with the SSD description on the bottom right.  Once again, we can see great low 4k random write scores as well as 4K IOPS at above 70,000 for both QD4 and QD16.  The sequential write score of 455MB/s seems a bit low so lets keep an eye on how things shape up in comparison testing.

Lets push things just a bit and see how high we can pull the total IOPS:

blankblankThe write scores remained consistent but we were able to pull the IOPS up to 77384 when we tweaked the test to QD 32 in mixed read and write mode.

    On what FW-Version hast this test been done?

  2. blank

    I have this drive, performance is good, only issue I have is the connector design, its held by 2 small pins and is not secure compared to my ocz

  3. blank

    I have this drive and the cable connector in the caddy broke. I’m considering using a cabling to connect direct now instead, but can’t determine the voltage of this unit… any ideas please? Lindy do a nice unit…

  4. blank

    im currently thinking on buying this one, anything in it’s price range that i should be comparing to?

  5. blank

    I am more curious when the price for a 250GB+ SSD will be less than $100.
    I would want something like this Corsair 240 GB SSD Force serie GT or the Samsung 850 EVO or PRO. But if you want to get a normal capacity for your system, then anything less that 200GB is no good.
