It's pretty much an inevitability: our out-of-the-box smartphones
are nice and fast, but before too
long, they demand a refresh for a slight taste of the original performance
parameters. This is especially true on Android
both for smartphones and tablets
of which I have a lot of experience), and there are many excuses for it. A poor
file system, "bit rot", too much bloat, and so forth.
If a research team out of Seoul has its way, we could see some
dramatic improvements to both performance and battery life in the future. The
tech is called WALDIO, an interesting acronym that stands for "Write Ahead
Logging Direct IO". Where's WALDIO? Under the hood, taking on the role of
Flash memory can become well-worn over time
There are a number of different things WALDIO does to achieve
its goal, but it ultimately cuts down on writes to the flash memory, preserving
its life and performance, while at the same time improving battery life as a
direct result of the eased I/O load. The tech utilizes both the standard ext4
file system and SQLite database system, so it's a top layer that's responsible
for these improvements.
WALDIO's creators claim that over time, the speed of smartphones
can be improved by 14x (versus well-worn devices), while devices with a
built-in battery could see improvements of up to 20x. Because of all the saved
writes, battery life can be improved by upwards of 39%.
If WALDIO can do all that it says it can, and doesn't impact the
integrity of our data at all, it looks
like a good bet. Whether or not the market will pick it up is another story.
