    I use an SSD in my MBP as the main boot drive. I am running an app called Keep Drive Spinning, a simple little app that writes/ erases a file to a USB drive attached to my AEBS once a minute. Keeping the disk awake improves the response of my aTV and iTunes when accessing the media files I have on the drive. It eliminates the lag while the drive spins up.

    My understanding is that the Mac will optimize the its internal SSD when the Mac is not used for a sustained period (like overnight). So my question is, if the Mac is writing this file every minute, does that prevent the Mac from doing it optimization of the SSD, as there is no long time that the Mac is not used?

    Optimizing a SSD usually involves the trim command, so writing a small file will not interrupt anything.

    A modern SSD is fast enough that there is no lag on access, so your utility does nothing. You are better off turing off Mac sleep in settings, and skip the utility.

    Mac sleep settings are off (except for the screen). The media I access is on a NAS which is a Fantom Green Drive HDD not SSD. So I use the Mac to keep the drive spinning. Fantom does not give you an option to turn off its "energy saving" protocol (at least not that I have ever found).
