Flash memory breakthrough results in 14x faster writes, cheaper phone storage

The read/write performance of current phone flash memory storage is not very efficient, as numerous frequent recordings in large batches lead to slowdown and deterioration over time, as any handset owner can attest after a few months of usage. Korean researchers from the Computer Science and Engineering at Hanyang University led by Professor Won You-jip, have developed the so-called Write Ahead Logging Direct IO (WALDIO) method.

It records information only when necessary, and in much smaller batches, at the same time avoiding duplicate recordings by the mobile OS. This gentle use will not only allow cheaper flash storage to be used with the same effect as more expensive one, but it can also extend the lifespan of said storage by up to 39%, the team discovered.

Perhaps the best advantage of WALDIO, however, is that it prevents the slowdown that numerous unnecessary record/erase cycles result in with the current technology. Without those frequent interruptions gumming up the works, the researchers recorded up to 14x increase in speed, which for phones with embedded battery (i.e. most flagships and even midrangers now), can reach up to 20x. The researchers are currently presenting their results at the USENIX conference in Santa Clara, California, and hopefully we will be able to see the tech implemented in handsets soon.

I am looking for the day when I don't have to pay $100 more for more storage.

Can thank apple for that pricing structure!

The day will never come if we keep having all those average consumers with no real mind to judge if they are really truly getting a good deal. If people would have stop buying iPhones with higher storage bc of the price ratio, Apple would have change how much they charge those higher GB models by now. Beside, new tech + cheap to make = high retail price.

Korean scientists hmm ... Wait for Samsung and LG to adopt this technology :O!

Well they will just use cheaper memory chip to make bigger margin.. nice!

Read the article just to say this, we (the consumers) will be charged more... because it's faster!

Well, so so, we can simply not buy the products that rip us off, but lets face it we keep buying because we want the latest and greatest regardless of knowing how big a profit margin the companies have. Look at Apple, they have the biggest profit around, they pay less and less to get their stuff made and their prices increase, yet people buy it constantly. They are great at marketing and making you forget that you are paying quite extreme amounts of money compared to what you get. That said a lot of other companies can't get away with this, so it is quite odd. And I have no idea what this new tech will mean :/

Nice work. Standardize it ASAP.
