actually, you know what? this is a moot point.
i'm not replacing my system partition; that is, my C: drive will remain on an older drive.
the new drive will neither launch the os, nor launch programs, nor do 
anything else that would be faster over ssd. it will simply store data.
i really just needed a lot more space.
there are currently 3 250 gb hdds in there. i bought it with four. it's 
split into a lot of partitions, including a 50 gb C: drive. one of the 
drives is solely for music, and that won't change. what i'm going to do 
is combine a lot of the smaller partitions together into a larger 
"discography" partition that will utilize the entire 2 TB drive. this 
will include things like wavs for burning cds and isos for burning dvds 
and blu-rays, as well as all of my source material, organized in iso 
files. so, it's all data storage.
as i move things to the new drive, it will open up space on the old 
drives. so, the remaining partitions (the virtual machine partition, the
 temp partition, the install script partition) will be able to grow. 
extra temp space will be useful, but it's otherwise not going to be much
 of a change.
again: i didn't buy this to increase speed. the machine is already 
blazing fast, because it's very well maintained (software. not 
hardware.). i bought it because i needed more storage space. and, that's
 the only change i'm expecting - more storage space.
