SAMSUNG 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)

Excellent choice, is a new product. Thanks amazon.

I tried it on Mac Pro 2011 and Mac Pro 208 and booth are working perfect. The performance is much much faster, restarting the laptop or opening a program is 80% faster than before especially after installing Yosemite OS

great product, i buy this for all of my customers (excellent price too)

Very good product and makes my computer run faster

I play a lot of open world games, and this loads the textures so fast! Also, boot times are 1-2 seconds all the time.

Excellent product! Nothing to complain, very satisfied! Excellent upgrade!

Every thing seen was fine except one problem is can not install Microsoft visual studio .

Very happy with the quality, and made my ole laptop faster than a new laptop with a normal hard drive. It only cost a little more than the old stock hard drive but runs so much faster.

Samsung still makes the best consumer SSDs. Enterprise is another story.

thanks
