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.
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.
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.
