I am gonna buy a 120 gb ssd and checked , nearly everybody suggest samsung more and also it is more expensive. why ?
The Corsair Force GS is good SSD, above average in many ways as the review in the link shows, but this page of that review will partially answer your question:http://www.guru3d.com/articles_pages/corsair_force_gs_240gb_ssd_review,14.html
Note that the review is of a 240GB Force GS, which will have faster write speeds than the 120GB model. See how the sequential write speed is much lower than the specs, by almost 50%. That is caused by the SandForce controller used in a GS, when it must deal with data that is 100% non-compressible. Real world data is about 60% compressible, so the real world performance will not be that low. The GS specs are based on a test called ATTO, which uses 100% compressible data, the best case for a GS SSD.
It's important to understand that the "500MB/s Read Speed" specs are only for very large files, of 1MB and greater. Most files are much smaller than that, a Windows boot is all files smaller than that. The same test in the review shows the GS 4K file size read speed, 20MB/s, which is most important for an OS drive. The Evo's 4K read speed is almost twice that speed.
Unless you are constantly writing 10MB - 100MB files, super fast large file write speed is not important.
