Could new self-healing flash ensure flash's long-term viability?
Today, I ran across a really cool article that discussed a potential solution to one of modern’s storage’s most vexing problems: flash wear. While some techniques, such as wear leveling, have been put into production, these techniques work around the problem rather than directly address the root cause. With wear leveling, solid state disks spread out data automatically so that a angle cell isn’t constantly subjected to the read/write cycle. Often, after around 10,000 read/write cycles, a cell fails, rendering it useless.
Now, engineers in Taiwan have developed a method by which this number can be 100 million cycles rather than just 10,000. If proven as possible and it’s actually achievable en masse, this technique could revolutionize flash storage. For more information read this article about the solution.
