The new full-disk encryption feature that’s enabled by default in Android 5.0 Lollipop comes at a hefty price in terms of performance, according to a recent benchmark report.
In fact, when full-disk encryption is enabled, random read performance drops by 62.9 percent, while random write performance falls by 50.5 percent, AnandTech reported late last week. Sequential read performance, meanwhile, drops by a whopping 80.7 percent. The bottom line is “serious negative implications for device performance in any situation where applications are reading or writing to disk,” the report concludes.
