    SanDisk Ultra II 480GB now powers my new Alienware Aurora R5
    I bought this SSD to install in my new Alienware Aurora R5 computer (Purchased 7/12/2016) . This was one of the components I wanted to upgrade, Alienware wanted to use a PCI express SSD, and I wanted that slot for an Elgato HD60 pro card. The computer came with an existing 1 TB Harddrive, and I wanted a faster boot speed in my new machine. The SanDisk arrived promtply in a brown envelope, through the carrier (UPS).This is what I did with the Sandisk: Installed the SanDisk Ultra 480GB drive (You will definitely need an SATA cable, it does not come with one. Be mindful and look at the placement in your computer, you may want a L-shaped connector, as opposed to a straight one.) Booted the machine Made sure the computer was recognizing the new drive (Checked in Reflect) I used Macrium Reflect Free to clone the existing 1 TB Hard drive (This took about an hour for cloning 90 GB and extra partitions). -Initially hit an error because was copying a 1 TB to this smaller drive, so I drag over all smaller existing partitions first, and then dragged over the main drive partition last. (Biggest one)I removed the original 1 TB drive and replace it with a 3 TB hard Drive.After successful boot, I installed the Sandisk tools (link provided in the instructions.)Results:From pressing the power button my computer boots to the first login screen in about 17-19 seconds. A considerable improvement.Responsiveness has improved along with loading speed for applications.
