Summary: SSD hard drives are the way to go. I bought this on sale between Thanksgiving and Christmas last year, 2013. I installed it in my desktop computer. I had to buy a mouting kit for it to fit in a 3.5" bay. My system boot up times are about 2-3 times faster.
Summary: I use this as an external drive (yes, this greatly limits the speeds due to USB 3, but I've had it with my old external HDD that would take forever to open in File Explorer) This is rugged, at least more than a hard drive.
