I noticed this as well. HD tune shows such a graph. The speeds are high in the blank erased areas while reading back written data is slow. This was with a new drive. So I think it is a part of how the drive works. I think many of the drives use caching inside the drive so reading back recently written data is fast but once the data gets old, reading it back is much slower.. Although using some command line utils shows read speeds much faster speeds than HDtune shows but still not as high as those in the reviews. The strange graph was surprising since I never saw such a thing on any review. I assumed they did not really write any data but just speed checked it after erasing the drive. Or read a file back they wrote it for a speed check. I also assumed I got a bad drive until I saw this message which showed my results to be similar as well.
Also dont use compression. The computer is fast enough to decompress that data on the fly but when you have a lot of cache files, you notice the speed loss. Something else that I found out the hard way when I noticed it taking 10 seconds to show a web page that I refreshed. It slows down the entire system. Although with a hard drive the slowdown is not as noticeable and with compression the HD was faster than the SSD but without compression the SSD is much faster.
Over all, my SSD is not much faster than my 7200RPM hard drive. It saves a few seconds here and there. Not really worth 10 times the cost.. SSD's are great for battery operation. Not so great for desktops. Save the money and install more ram would show more speed improvements.
