Approximately 1 year ago I posted the following post when my Macbook Pro was just out of the box:

It is just over 1 year later so lets see how it compares.
Macbook Pro (128GB SSD) after 12 months intensive usage:
Sequential 63.36
Uncached Write 45.24 27.78 MB/sec [4K blocks]
Uncached Write 50.40 28.52 MB/sec [256K blocks]
Uncached Read 62.72 18.36 MB/sec [4K blocks]
Uncached Read 190.88 95.93 MB/sec [256K blocks]
Random 106.57
Uncached Write 51.56 5.46 MB/sec [4K blocks]
Uncached Write 64.32 20.59 MB/sec [256K blocks]
Uncached Read 1672.77 11.85 MB/sec [4K blocks]
Uncached Read 500.88 92.94 MB/sec [256K blocks]
Notes:
I did not reformat the system at all. The Snow Leopard upgrade was all that was done to it so the SSD has not benefited from a clean format.
The SSD has been heavily used during the last year filling the disk almost completely and emptying it almost completely 3 or more times per week.
