Better way to load data to table

Hi;

I have a table that has four fields as float8[].  I have a serial new data
for each array.  Each time I have new data I have to update more than 6000
rows for all four field.  But using "update (ta ble)" to load in the new
data is just too slow.  Does anybody know a more efficient way to update
large data set in an array?

Thanks for help.
