Long but interesting AnandTech article on SSD performance - 03-18-2009, 07:52 PM
This article goes into great detail about performance differences due to controller chips and the "SSD slowdown effect". It is a VERY long article but worth the read.

I started a benchmark thread but I can't figure out how to use the benchmarking app. viewtopic.php?f=11&t=5353&p=44198#p44198

However, a bit of the answer has probably already been discovered. Here's an example, from CrystalDiskMark from this post.
Sequential Read : 77.638 MB/s Sequential Write : 11.598 MB/s Random Read 512KB : 70.559 MB/s Random Write 512KB : 2.590 MB/s Random Read 4KB : 9.362 MB/s Random Write 4KB : 0.232 MB/s
Sequential Read : 84.169 MB/s Sequential Write : 26.071 MB/s Random Read 512KB : 79.542 MB/s Random Write 512KB : 20.420 MB/s Random Read 4KB : 10.959 MB/s Random Write 4KB : 1.859 MB/s
BUT even the stock STEC has a random 4kb read of 9MB/sec, which is really amazing if you think about it. That demolishes the best conventional hard drives.
EDIT: I meant to include this bit of data: the VelociRaptor (one of the speediest conventional drives) has a random 4kb write speed of 1.63MB/sec. Some SSDs are better than this but cheap ones can be MUCH worse. The Runcore looks approximately equivalent to the VelociRaptor in this specific benchmark, so that's a good sign.
EDIT2: minor edit to fix an misleading sentence.
