if you would like to test it out we can swap it into my i7 and test it again and see what the speeds are. Then you will have proof.

This is mine and there is no way to cheat.
Peter has a 256gb Apple SSD but it is in a MBP 13" 2008. His is substaintally slower then mine due being one of the original drives apple offered as an ssd.

All of this was with 4GB RAM since finding other systems with 4GB is much easier than 8, and the 4GB is factory where as the 8 is Crucial.

I found this kinda cool. Here is a MBP exactly as mine with the original Vertex
http://db.xbench.com/merge.xhtml?doc2=374372
Now look at my OWC versus the Vertex 2...these are probably 2 of the fastest drives available...
http://db.xbench.com/merge.xhtml?doc2=461848
Overall, the Vertex 2 is slightly faster than the OWC, but it is pretty close. It's also worth noting that faster systems than the 13 inch 5,5 MBP have benchmarks for both the OWC and Vertex 2 showing MUCH faster speeds. Also, more RAM really changes my Uncached Read, which in this test with 4GB of RAM is pretty bad. Keep in mind SSDs often have rather low Uncached Read speeds.
It's also worth noting that the Crucial C300 is very underrated speed wise and despite not being SandForce controlled, it is still exceptionally fast.
CHECK OUT THIS OWC!!...it's almost 500 in an i7 MBP

I notice that some of the older SSDs perform better in these tests, but the newer drives with SandForce controllers tend to have better real world performance.

I've noticed the SandForce controlled SSDs have terrible Uncashed Read speeds on the 2009 era MBP...but the same drives on other computers, while still slow comparing to all other disk speed tests, are significantly faster. Any idea?

Here is my result. I just installed this drive on Saturday.
We have the same drive... Why are my results so much slower than yours? 3-day-old drive, fresh install... Macbook Pro 13" 2010 base model.
EDIT: Nevermind, I need to work on my reading comprehension skills.
Except that Xbench hardly dictates real world performance.
Absolutely, and it seems many people also question Xbench's reliability in predicting anything in a semi-precise manner.
I don't know how often it has been said on MacRumors;
DON'T use XBench any more, especially not for benching SSD's.
The software is 5 years old and was neither made for SSD's, nor for any other modern hardware. It just doesn't scale with today's tech and gives completely unreliable results.
I did an XBench with my Intel as well; results from 160 to 300. You can hardly rely on the numbers you get from that software, so best you can do is to select it, and press delete!

XBench and all other benchmark programs are made to gauge and estimate capability. This is completely limited in real-world meaning because it cannot estimate the performance of the system based on the individual user's customization. Furthermore, the highest importance in regards to performance is user-satisfaction. All of the benchmark systems simply give you a bunch of numbers, which to most people means nothing.
Obviously, gauging hard drive speed gets even more complicated because no one uses a hard drive exactly in the manner that benchmarks test and the variation seen, which is largely dependent on the user, has no ability to account for this.
