The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of a solid state drive (seek times massively lower than hard disks) may create a situation where a much smaller allocation size is not detrimental.

Were this the case it would at least partially help to overcome the disadvantage of SSD (massively higher prices per GB).

Is there a way to determine the 'cost' of smaller allocation sizes specifically related to seek times? Or are there any studies or articles recommending a change from the default based on this newer tech?

(Assume the most average scattering of sizes program files, OS files, data, mp3s, text files, etc.)
