Buyer beware purchasing a Razer blade laptop... Despite the great specs, they’re known to have a bunch of issues(that the company is aware of), and have a reputation for the worst customer service imaginable. Check the reviews on Amazon of customers who’ve owned one longer than 6 months. I had been wanting to buy one for a long, long time... but after doing more research and reading the numerous horror stories of others who purchased a Razer blade, I changed my mind about buying one.
The UHD screen is kind of overkill on a 12.5 layout. There are some good teardowns of the device already. Looks like Razer really put a garbage SSD in the 128GB models so those should be avoided at all costs. IMHO, the success of this device is entirely dependent on the Razer CORE. If that unit is overpriced or performs badly, you can find ultrabooks that offer more for less.
but you can play from an external hard drive. the SSD is just handy for fast boot times and here is a video from NCIX tech tips to proof that you can play games via USB 3.0
