Flash Destroyer Tests Limit of Solid State Storage
An anonymous reader writes "We all know that flash and other types of solid state storage can only endure a limited number of write cycles. The open source Flash Destroyer prototype explores that limit by writing and verifying a solid state storage chip until it dies. The total write-verify cycle count is shown on a display — watch a live video feed and guess when the first chip will die. This project was inspired by the inevitable comments about flash longevity on every Slashdot SSD story. Design files and source are available at Google Code."

Flash! Aa-aaahhh!!
Wait, which flash are we talking about here?
I was expecting something cool, like storing a picture, displaying it, and then constantly XORing each pixel with some random number twice, repeatedly, and watching the image decay over time. Although it would appear that it'd need quite a lot of time.
Now, to see how much explosives it takes to MAKE it fail!
This is my favorite part! :-)

If you have any important data on that drive, urine trouble...
They could add an extra digit to the front of the display showing how many times the other numbers have reached their maximum! Brilliant, 10x the capacity for only one digit more!
A SSD with flash that averages 1,000,000 writes before blocks start to fail but does it gracefully with little/no data loss could be better than one that averages 2,000,000 but goes out in a blaze of glory as soon as the first block fails.
That depends on how you define "better", and for my personal definition, it depends on exactly how glorious a blaze it is. :)

That brings to mind an old favorite of mine: the Light Emitting EPROM. The power pins on EPROM chips are in opposite corners. Plug in the EPROM chip backwards and you've hooked the power up backwards. Result: A light emitting EPROM, though one with a very limited service life.
