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.

The biggest and for that matter only issue we have found with the SandForce drives is how they handle compressed data. It is actually kind of odd the way this works since the reason why they are so fast at everything else is the same reason why compressed data writes slower. SandForce's proprietary Durawrite technology is able to compress data as it is written to the drive but compressed date is not easily reduced any further so it needs to be written in full to the disk.
It is because of this that the Crucial RealSSD C300 is able to transfer these types of files faster than the SandForce drives. At the 240 to 256GB capacity range a user will have more compressed data on their hard drive than at 60 or 120GB so you really need to start looking at what you do with your compressed data more. Most of these files are just played back at set speeds, speeds that either drive can handle easily but if you are constantly moving MP3s and AVI files from one place to another at full speed then you start to get into a situation where the C300 starts to flex its ability to use SATA 6G. Most users are not going to move these files around at full speed and transfers will be limited by either their internet connection or their LAN speed.
With the SandForce drives outperforming the C300 256GB drive in a few of the Vantage tests and the logical thoughts on how compressed files are handled I am starting to lean in favor of the Agility 2 over the C300 in this capacity size.
