It's no longer hard to get a hefty 128GB of storage in a smartphone, but that doesn't mean you'll enjoy it. What's the point of all that extra space if your phone chugs handling huge games and 4K videos? Samsung has clearly anticipated this problem, though -- it just outed the first 128GB flash memory chip based on the speedy Universal Flash Storage standard. The part uses tricks like command queuing and a serial interface to give you the kind of breakneck performance you'd expect from a solid-state drive in a PC, not a device that fits in your pocket. It's about 2.7 times faster at random data reads than the flash you see in many high-end phones, while its sequential speeds are "up to SSD levels." And that's while using 50 percent less power -- you won't have to take a hit to battery life.
