One of the quirks we encountered with Kingston's original Wi-Drive was its capacity. For a device that's all about expanding storage for Android and iOS devices, it didn't have much more to offer beyond what we already had. We can at least put that issue to bed now that there's a 128GB version. The extra space doesn't change the WiFi drive's four-hour battery life or design, but it will give more breathing room than virtually any current microSD card. Although there's no immediate mention of a price, we're seeing the 128GB capacity on sale for $181, or about twice as much as a 32GB edition -- a small enough gap to suggest that going bigger is better.
