SSDs are worth it. They can improve your work flow substantially.
That said, 256GB isn't a lot if that's your only storage medium. Windows will take a good 15 or 20GB or more.
Add in some programs and the fact that it's good to keep 10 to 20% SSD space clear for garbage collection, aka maintenance
and you soon have no space left for those bulky files you mentioned. So yes, get a hybrid drive and you can perhaps get
a 50/50 deal of both worlds. There's hybrids which have more SSD space though.
