So far as I can judge, there is no file fragmentation on the EHD. It will not let you do the transfer if there is not enough contiguous free space for the whole file.
Let's say you have 10GB "available" and try to transfer a 2GB, it may not go because of the fragmentation of the free space when it looks for a place to put it. That does not happen on a new disk, only on those with programs deleted and new added. The internal disk and most modern computer systems do provide extension blocks--not so on the EHD's EXT3 system, AFAIK. The only "defrager" that we have is to copy the files/programs to a new empty one.
Typical storage is 1.3 to 2GB/hr for MPEG-4, 4 to 7GB/hr for full-channel MPEG-2 as in OTA without sub-channels. I've had problems with change in PBS broadcast here even with local-into-local (LIL) programs. It went from 6-7GB/hr OTA to 2GB/hr with LIL and now that LIL is back to 6GB/hr even with 1 sub-channel. This is hard on my archive.
