In tech space, even 9 years can produce 1000x results. I love this microSD storage example, 2005 vs 2014: http://i.imgur.com/1jyVev4.jpg

I had a similar realisation a few days ago - I was putting a new microSD card in my phone, and realised that it represented 100 times the storage of my first PC (200GB vs 2GB). I still get a feeling of "this shouldn't be able to store this much" every time I use a microSD card.

I love looking at MicroSD cards and imagining how, in your example there are 1,600,000,000,000 individual storage units inside it.

That's 200 x a billion x eight.

>this shouldn't be able to store this much

Same here. I was thinking about how many CD-ROMs it would take to store a certain amount of information, as a measure of just how much data something amounted to. Then I thought that with microSD cards, the same amount of data would sound much less impressive.

Nine years to change one letter? Jeez, and we pretend that technology moves fast.

3 letters, the X makes it sound cool.

What's the average/expected lifespan of a microSD card vs. a flash drive vs. a CD-R/DVD-R. I've seen various graphs but does anyone have even anecdotal personal experience?

Well anecdotally, I've never had a single storage piece die on me. The only exceptions are two microSDs that got fried in my rpi. Apparently you shouldn't constantly read/write to them, and instead just put boot files on it and move everything else to usb.

You can read them as much as you like. It's the constant writing that can be an issue.
