For some reason, I usually manage to kill the mechanical drives in my laptops after a year or so of usage.
I lasted three years on the stock HDD, including a nasty fall off a desk while running. After I upgraded to my 840, I stuck the old HDD in an external case, dropped it while (holding it a few inches above a table and) not running, and killed it. Good job, self.
1TB of flash storage in either a single drive or RAID array is at least $600. You can get a pair of 500GB drives, but those are at least $300 each. Crucial M500s MSRP for $600 and occasionally drop a bit below that. A trio of 360GB drive will probably run about $700-750. Most people won't spend half or more the price of a computer for one component.
I've actually considered downgrading the 1TB Scorpio Blue, which has two platters, for a 500GB Blue with a single platter. Less mass to move means better battery life and fewer moving parts means less chance of failure. I've also considered downgrading to a 64GB SSD in my laptop, using the now-free 120GB drive for my desktop, THEN getting a second 250GB drive for RAID 0. I can justify that after the next Steam sale.
