best way to store 'ghost racer' data

[Flashkit]

Has anyone had to come up against the need to store in a database a large array of data. Im recording lap data for ghost riders, and the resulting textfiles as pure array data are 60-100k (thats a sample every 100 - 200 ms)

I am thinking that Ill take this data array and maybe use a byteArray compression on it and then whack it into my mysql database as binary data.
But I havent the foggiest as to how to go about it.....

Any suggestions on a best practice for this most gratefully accepted
