Nanotube Memory Finally Beats Flash For Speed 86
holy_calamity writes "Although flash memory that stores each bit on a single nanotube has been tinkered with in the lab for years, it has always been much slower than the devices in use today. A Finnish team has now cracked that, demonstrating single bits of nanotube memory that can be written in just 100 nanoseconds. Existing flash memory takes tens of microseconds."

Your average Flash chip does 100k erase/write cycles. 18k is certainly reasonable for new tech, which will certainly improve over time. The number refers to the number of operations per erasable block (or it will in the future), so in practice you get a much larger number of total I/O operations on the entire chip, given a reasonable wear leveling algorithm.

How much latency does that algorithm add? They are only testing one bit. Won't a controller and the wear-reducing slow it down a fair amount?
Still a ways to go:
"The next challenge is to join an array together into a working memory chip, as the team has so far only tested single carbon nanotube elements. And although they have only proved capable of "remembering" data for several days after the power is cut, the team are confident this can be extended."
Several days is a pretty short life for SSD...and longer

Let's say they make this into a thumb drive. Now, let's say that you read/write the entire drive twice a day. That's four operations. 18,000/4/365 gives you twelve years of this. Even if you are filling and then erasing the drive ten times every day it is still two and a half years of use. Less than you can do with current flash memory, but fine as a proof-of-concept.

CD-RW will only last for 100 writes. Have you ever seen a failed CD-RW? I didn't. Even if you had a nanotube drive that you completely overwrote every hour, it would last for 2 years. An USB drive with 100k writes would last for 11 years. In real life scenarios drives are rarely written to more than a few times a day, and certainly not in the same places. This can be further reduced with wear leveling filesystems. The only reason we don't use those widely is that it's extremely hard to write a filesystem dr

I used packet writing quite a bit for a while and I think I killed a few CDRWs with it over the years when I used it.
However the vendors fucked up on thier software. Adaptec and ahead came up with incompatible packet writing software and even if they had been compatible bundled copies of nero didn't generally come with incd. So as the burner vendors switched to bundling nero packet writing died out at least among those of us to
