Yeah, I saw posts by people doing video complaining about such
things. One good suggestion was to create may small volumes for
separate projects and just do a fast format on them rather than
trying to delete folders.
I got procmon to see what is going on. Win7 has doing indexing
and thumbnails, and there was some virus checker going on, but
you can get rid of those. Still, most of the problem just boils
down to the duration of the delete on close being proportional to
the size of the file, and apparently related to the access times
of the disk. I sometimes see .25 sec duration for a single file
during the close of the delete operations on the hard drive.
I've been using an intel 510 series 120GB drive for recording
concerts. It is hooked up with an ineo usb3 adaptor to the front
panel port of an rme ufx recorder. The laptop is just used as a
controller ... the ufx does all the mixing and recording to the
hard drive.
