I need to install parallels, windows 7 and visual studios for C# programing in school and my hdd is way to small. So i´ve looked around and I can probably install everything on a usb- flash and use that whenever i need to. The only problem are that i don´t know what to look for in a USB-stick. Is it the read or write or both? How much should i spend on it and so on? What do you think of this? I have usb 3 on my mac. I´ll get if for around 53 or $67 incl. shipping. USB3.0, 64 GB max. 110 MB/s write max. 245MB/s read http://www.computeruniverse.net/en/products/90465504/sandisk-cruzer-extreme-usb3-0.asp#faq Any thoughts?
