AS determines the performance of Solid State Drives (SSD). The tool contains four synthetic as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD. These tests are carried out without the use of the operating system caches.
In all synthetic tests the test file size is 1GB. AS can also determine the access time of the SSD, the access of which the drive is determined to read through the entire capacity of the SSD (Full Stroke). The write access test is only to be met with a 1 GB big test file. At the end of the tests three values for the read and write as well as the overall performance will be issued. In addition to the calculated values which are shown in MB/s, they are also represented in IO per seconds (IOPS).
Note: AS SSD is a great benchmark for many tests, but since Crystal Disk Mark covers a broader range of 4K tests and HD Tune Pro covering sequential speeds, we will only use the Copy Benchmark from AS SSD.

Up to this point you would think that the SandForce SF-1200 is the be all to end all SSD with no faults what-so-ever. One of these days we may actually see an SSD like that but today isn't that day. The same technology that reduces write amplification and makes the Corsair F120 so fast is also its weakest link.
When dealing with compressed data, the SF-1200 has to take its foot off the accelerator as if it were about to drive over a puddle water. As you can see none of the other SSD controllers have this internal speed bump but at some point you have to calculate just how much compressed data will be on your drive.
My logic behind this is simple, the smaller the drive the less compressed data you will keep on it. Your operating system does not grow with the size of your drive; it is pretty much a fix number. The same is true for your must have programs like Office, WinRAR, Skype and anything else you will install regardless of capacity, these are static.
On the dynamic side of things is where your compressed date comes into play. MP3 and AVi files are good examples. These have already been compressed and move slower on the Corsair Force. The good thing about AVi and MP3 files is they only need to play at a fixed speed and the Corsair F120 is able to handle that speed many times over. The only real world area that you will see a difference is when moving them from one spot on the drive to another. On a 120GB drive you are not going to be moving things around that much to start with and after your essentials are installed you are not going to be keeping a whole lot compressed data on the drive.
