It’s worse this time. Microsoft was roundly pilloried for low functional storage rates in the Surface RT tablet. It appears that the big sibling to that device, the Surface Pro, suffers from similar woes. The 32 gigabyte Surface RT had 16 gigabytes of free space. The 64 gigabyte Surface RT had 46. In short, for the lower-end Surface RT tablet, only half of the reported storage was up for user files. But like we said, it gets worse. For the Surface Pro 64 gigabyte device, a shockingly low 23 gigabytes are open, The Verge has confirmed with Microsoft. That is it. At the moment, TNW cannot confirm figures for the Surface Pro 128 gigabyte model. However, the figure for the 64 gigabyte device means that a mere 36% of the listed storage is open for general file storage. If there was ever an argument for SkyDrive, this is it.
