Outside of shits and giggles do you have a usage need for almost 2TB of stupid fast storage?
I use it primarily as a utility/working partition, housing my OS, main apps and a few game installs (everything but Steam). I never fill the partition (to preserve the speed, as SSDs don't like being stuffed full), and indeed have never filled it past 25% of capacity. At the time, the MAX IOPS was one of the fastest SSDs around, and I didn't want to incur the speed penalty by dropping to a smaller drive. Besides, it's better to have the space and not need it, than to need it and not have it.
Not much out there above a 30" $1,200 monitor thats usable at a desk in any realistic manner unless you're talking multiple monitors... I guess you could buy the $4.5k Sharp PNK321 32" 4k Monitor
