To have higher read/write speeds; isn't that generally the reason people use them? Because they're faster?
Higher read/write speeds do not effect mp3s or video/photo files, as the actual file size nullifies it in any practical way (other than copying in bulk, I suppose).
But you're saying it like people, normal people, lug around external hard drives with them or even have them to store backups on; the average consumer uses his computer and "maybe" an external monitor, if that.
This is the Mac Pro forum. There is no lugging, these are gigantic machines with four drive ports that are not portable...
EDIT: well, I suppose there MAY be some lugging. I'm actually always amused by colleagues and even friends who lug these huge NEW towers (I'd understand if it was cheap, older hardware) for remote recording. Have they not heard about laptops? They're not just for internet porn anymore...
Nobody puts files on external drives. Maybe "we" do, as we are enthusiasts to soem point, that's why we are here.
The average person does not. I'm making assumptions and basing opinions on the majority of the population, hence my stating of "normal".
The average person also doesn't need an ssd, it's a waste of money on their part. If you're enough of a gaming enthusiast to be buying parts specifically for gaming than you are enough of a techie to understand file structures and how to separate system and application from media.
For that matter, average users probably shouldn't buy a Mac Pro. Like ever. The tower line is pretty much solely for pros at this point; not being snobbish or anything, just saying you're wasting around $1k minimum when an iMac, at this point in the technology, will give the average user pretty much everything they want and need at a price that makes buying a more expensive SSD (should you want one) feasible...
