SSD is really nice for one reason: durability. Regular hard drives have an arm, held in place by magnets, floating over a delicately magnetized disk. You drop your computer, that thing bashes the disk, data loss. Possibly minor, possibly fatal. SSD is literally nothing but a bunch of chips. Unless you chuck the entire computer in a shredder, it's VERY hard to do enough damage to make that not work.
Not on a laptop? Well, there is one other major benefit to SSD: seek time. Regular hard drives have to find where the information is, move that floating arm, and then read the information. That takes time (fractions of a second, but time nonetheless, and computers doing many things at once tends to multiply that time until it's noticeable..). SSD? Read address from chip, done. MUCH less time. This is shaving seconds off of any data intensive process from starting and shutting down the computer to writing and reading large files like movies.
SSD's only real drawback is that they are not quite as long lived as traditional drives. There have been a LOT of improvements on that in recent years, to the point that you don't need to worry about it anywhere near as much as you originally did, but a SSD has a maximum number of writes that you can make to any spot on any chip before it wears out. This is usually numbered in the thousands (and modern stuff, hundreds of thousands), and there's software that's automatic for these things called wear leveling, that keeps that limit from endangering your data, but it's a limit.
Super valuable for laptops. Not so much necessary for desktops, but still nice.
