SSDs good for 1000 years?

[quote=http://www.engadget.com/2014/12/05/ssd-2-petabytes-of-data/?utm_source=Feed_Classic_Full&utm_medium=feed&utm_campaign=Engadget&?ncid=rss_full&utm_content=gravity_organic_sitefeed&cps=gravity]Four drives bit the dust prior to hitting the petabyte mark (though still far, far past their specified limits), often after their SMART systems moved thousands of bytes from failing flash sectors.
However, two drives -- the Samsung and Kingston models -- have both written two petabytes worth of data and are still going. Given that a typical user might write a couple of terabytes of data a year on an SSD, that adds up to a thousand or so years based just on usage (the actual parts would disintegrate long before that, of course).
Ok, so not exactly a scientific study but does look promising.

whilst that is good, its worth pointing out a test with random 4k files instead of 10gig files would be more realistic and probably would fail earlier.

Re: SSDs good for 1000 years?

Were your file systems aligned at multiples of 4Kbytes?

@fox Not sure why you are directing the question at me. I just supplied a link to the article and didn't conduct the study myself Wink

Didn't they say the same thing about Cd's in the 1980's?!  I bought Cd's that barely lasted a few months!

If you have a piece of string in your pocket ... measure it.
Many factors could apply.

recently KitGuru have been trying to destroy 5 OCZ SSD , their warranty is 22TB .
over the past few weeks they stress test  them with ANVIL utilities  and so far all 5 have passed 100TB of data  without failing  Cool

Re: SSDs good for 1000 years?

This is just a small section of an article on SSD's
However, few data centers will experience rocket liftoffs or sub-freezing temperatures, and SSDs have their own unique stress points and failures. Solid state architecture avoids the same type of hardware failures as the hard drive: there are no heads to misalign or spindles to wear out. But SSDs still have physical components that fail such as transistors and capacitors. Firmware fails too, and wayward electrons can cause real problems. And in the case of a DRAM SSD, the capacitors will quickly fail in a power loss. Unless IT has taken steps to protect stored data, that data is gone.
Wear and tear over time also enters the picture. As an SSD ages its performance slows. The processor must read, modify, erase and write increasing amounts of data. Eventually memory cells wear out. Cheaper consumer TLC is generally relegated to consumer devices and may wear out more quickly because it stores more data on a reduced area. (Thus goes the theory; studies do not always bear it out.)
the article was taken from,  www.enterprisestorageforum.com
So it may be a bit early to quote a 1000 years.

Re: SSDs good for 1000 years?

I bet switching off the power for a year will cause more trouble than continuous use for a SSD.
