I'll say right away when I first received the device, it felt like the SSD case was made out of cheap plastic. It felt light and fragile, but that's to be expected since it's not made out of the same heavy metal components as a hard drive. However, when I connected it to my computer, I definitely noticed a difference. I tested Windows 7 Home Premium on it and it booted much faster than I've ever seen on a standard hard drive. It was on the boot screen for about 3-5 seconds (usually takes several minutes to boot as well as warm up after turning on). I don't notice any warm-up time with this hard drive. I then tested Windows 10, which boots even faster thanks to the "quick start" technique. Overall I would say this is a very good product and I am far from disappointed. Just make sure you know how to use the secondary HDD for storage, not the SDD itself. 120 gigs eats up real quick with that thing.
