EEPROM to storage data

Nice guides, but can that space be enough for me? I need to save time and value for each data that i retrive from a pressure sensor. I need to have 200-250 samples each second for 4-5 sec., but better will be for 10-12 sec.
Each data have time and a data value of 5 numbers(es. 200,00 kg).
How i can solve that? there is a microsd adapter that have a very low cost and a guide to connect it to arduino and libraries?
