I wonder what's the rating for the magnetic media. It may be expressed
in different terms, but if it could be compared, people would be shocked
how 'low' it was. Although the media may be rated to outlast the
mechanicals.

I'm happy to see these sorts of tests getting more attention. There's been a
tremendous about of FUD spread about SSD wearout. Under typical usage
scenarios, the SSD will be obsolete years, or even decades, before the NAND
itself will have worn out. Hardware.info did a test of two 250GB Samsung
840's as well, and they lasted over 3200 P/E cycles for over 750TB of
writes. These are the (presently) one-of-a-kind TLC drives that are
estimated to be rated for 1000 cycles. If the P/E ratings were accurate,
they'd already have a tremendously long useful life--but the ratings are
ultra conservative. Given a 10GB/day usage scenario (a high estimate for
most users) and a write amplification factor of 3, those drives would last
for ~80 years based on tested endurance, or ~25 years based on the
"guaranteed" spec. I know there are some that like to hold on to old tech,
but I suspect even Duncan would have retired the drive before then. :)

I don't know if anyone has been following this experiment, but after 200TB
of writes, even the weakest SSD (Samsung 840, which is what I
have) is still going strong.
