Asking which 3.0 stick to get, 32-128GB size so probably 64 preferred. There's plenty on market but it seems not all are good for booting. I want probably MLC NAND or maybe 3D one(does it even exist in flash stick market?) with some nice controller that does not overheat USB stick. What should I look at when choosing my model, I've heard that for booting it's 4k read/writes that are most important, is that true? Some sticks can be 300MB/s for 1GB readts but their 4k writes are like 0.005MB/s, while others are 100MB/s for 1GB and 1MB/s when writing 4k. Any clues?
