Is there a limit on number of write operations during software executioin?

I have a customer who wants to capture data to a text file at least twice a second during program execution.  The processes he needs to run may take weeks to complete.  Other than disc maintenance issues (the file grows at about 4 kb/minute during test runs, so not too bad), is there any other performance or other limitation that I should be aware of.   They will be running the software (C#/Visual Studio) on a Windows 7 or above machine.  

Thank you for any advice.

Limit is as much as the hardware will allow as far as throughput but if it's only 4kb it shouldn't even be noticeable on modern hardware. Maybe the amount of RAM if for some reason your are loading the file into memory. Maybe check to see that the file is excluded from antivirus scans to prevent conflicts and add as much error handling as possible to ensure all intended data gets written to disk.

I'm sure you're handling or not worrying about external events such as power failure or hardware failure. disable any automatic software updates during the timeframe especially if anything may trigger an automatic reboot.

4kb per minute, but even over a 2-3 week test procedure, I guess that is not too large for each individual file.  As far as RAM, it's just a writeline over a temporary StreamWriter object, so I don't think it will stay in RAM.  Thanks about the antivirus update tips.  Regarding hardware/power failures, yes, they are being handled.

Good advice, generally.
