Background on Solid State Drives
Solid-state drives (SSDs) store data electrically, rather than on magnetic disks like traditional hard drives (HDDs). This means there is virtually no delay when seeking a specific bit of data, and if the drives are well manufactured they can also perform faster at both reading and writing than most hard drives. Because it is a newer technology the price per GB is a lot higher than traditional HDDs, but it is coming down quickly.
These drives also tend to be offered in 2.5" sizes, meaning they can fit in laptops just as well desktops. Early models are not as energy efficient as laptop HDDs, but they are a lot faster - so if you don't need a ton of space they can be a great mobile drive solution. There are also smaller form factor options for SSDs available in some systems, like mSATA and M.2.
I love the SSDs. Prices are getting better, the performance is excellent, and they're incredibly reliable! One of the common worries I get from folks is that they'll wear out quickly. We've been carrying them for about seven years and our failure rates on these have been well below that of our platter drives. On top of that, the theoretical lifespan of these drives is something along the lines of 15-20 years (or more) with typical use. It's just not something I worry about with SSDs anymore.
