Filesystem or database

Hi, This is just a quick query as I am bit doubtful of the result.. basically, I get the username and ip of a person who logs into a remote site and i have to save this data (please note that this would be thousands of logins) so I was wondering if it would be better to save the username and ip as an empty file where the filename contains both... e.g: <username>:<ip> or in plain english: my_username:201.1.1.22 This would save me in hundreds/thousands of calls to the database and would (in theory) be faster as I would be accessing the filesystem instead of the DB.... Right? Sometimes i get no username but just the ip address, in which case I will first have to see if this IP is already "logged" by me, and if yes, match the username to the ip. All usernames:ips expire in 1-24 hrs, I will be running a cron to 'cull' these dead logins. Am I on the right track or is it too much of a hassle and just go in for the database option? Thanks!
