Rated 5 out of 5 by from Wow! This thing is FAST (but expensive). Pop it in an older laptop and it'll bring new life.

Rated 5 out of 5 by from new 2tb drive replaced my hard drive with this, if it works out, it wil be the last hard drive I need for at least 5 years, and possibly 1 new computer.

Rated 5 out of 5 by from Fast, Very Fast I was surprised at the fast boot up speed of my computer's operating system that I bought another one to replace the hard drive in my other computer. Before you spend the money to update your CPU for faster speed, try one of these.

Rated 5 out of 5 by from Its Fantastic I love the speed and ease of use with this drive. It comes with everything you need to clone a drive. I just went for a clean install and right away it didnt dissapoint. About 25 minutes to load Win10 and all the updates. Took longer for me to put my games and such on here then it did with the OS itself. I'm happy with this drive. Have had several others but they always seemed lacking. Thanks again Samsung with another great product.

Thanks to Samsung for such a great product and the price was great to.

Rated 5 out of 5 by from SSD 850 PRO 2.5" SATA III 1TB SOLID! SUPER SOLID SSD EVER....What you want to know is this: is this SSD faster than the 850 EVO? When dealing with SSD's, does any appreciable difference in speed occur, since they are all so fast, anyway? The fact is this: I've been using Samsung SSD's of varying varieties for years, and when I recently replaced my Samsung 850EVO with this one (on my boot drive), the speed notice WAS undeniably different. Yes, I still has those couple of seconds of booting time after the POST routine finished, but instead of programs loading, they almost felt like they were POPPING, this thing is so fast.Is it worth the price? Hard to say. First, is what type of computer user are you? What types of programs do you typically run? And what type of system do you have? For example, if the bottleneck is in another part of the system, you may not get the most bang for your buck by spending the extra on this PRO version. But if you have a modern, well-specified computer, you will notice a speed difference. I certainly did. And now comes the wait until the 850 PRO prices come down, because what you really want is something like this, but in 4Tb or larger. It will be a few years before we see such storage, and at reasonable prices, but this drive clearly shows it is coming. For now, if you are dealing with a desktop, consider my strategy of using it as the boot disk with all your programs installed, and other, less expensive drives for storage. If this is for a laptop, you have to ask yourself if your laptop is new enough and powerful enough (RAM, processor, video system, etc.) to warrant the extra expense. All SSD drives are fast, and generally, scream past the traditional spin platter drives we all grew up with. But there IS a difference in how the memory in an SSD is constructed and then, of course, there is the often-overlooked factor of the controller attached to the disk, which also has an impact on speed.Of all the Samsung drives I've purchased, this is the best, and fastest. Its a superb drive that is a window into the future of SSD drives.
