Corsair Performance 3 128GB.

It could be one of many but, no more or less than a standard HDD. I did not say ATTO was a perfect test. However, it is the test used to document the specifications by Corsair and most other SSD makers I have seen. Comparing ATTO scores to other tests that use compressed data is useless. But, this does not invalidate the results of either type of testing.
Example:

I understand your rationalization of using a particular test to show any drive in 'all its glory' so that it can sell to consumers like you and I, but consumers want to make sure the tests themselves can be validated. By no means am I knocking ATTO or you. I just think that ATTO tests one way and other tests test another way. I don't think there is one program that we can all rely on to say 'hey this is the drive to buy based on my results". But testing drives with several programs would be a good place to start.

Just my opnion but I think any benchmarks used to test drives should mimic real world use patterns. By this I mean internet, video/audio playback, archiving(zip,rar), video encoding, etc. Does ATTO provide this more than AS-SSD and CDM?

Well, so much for the reasoning behind using 25nm NAND for this drive...

On Corsair's side, the Corsair Performance 3 also uses 34nm NAND (http://forums.bit-tech.net/showthread.php?t=202245 ), but the C400 uses 25nm. Wonder how that will turn out ...

I think most of the performance issues simply comes with using LESS NAND chips on the design -- going say from 8x 8GB 34nm NAND to 4x 16GB 25nm NAND is unquestionably going to be slower, even if the 25nm chips are as good as the 34nm.

I don't think so. The sequential write speed is most sensitive to the number of channels. You can see this in almost all SSDs -- the lower the capacity (fewer flash chips, fewer channels), the lower the sequential write speed.

In the case of the P3, the sequential write speed is one of the highest of all SSDs, for each capacity. This points to the issue being one of firmware tuning for high sequential write speed at the expense of 4K speed.

That's a good point too, and a possibility, guess we just need to see some in depth reviews/breakdown of these drives.
