Apple I bought a brand new iMac on Tuesday. I'm pretty sure this will come as a surprise to some, so I figured I might as well offer some background information about this choice - maybe it'll help other people who are also pondering what to buy as their next computer.

the parts about ssd speed and lifetime sound right to me. even on fast new systems, hard drives still thrash left and right when doing lots of stuff.

and think of how many old semiconductors there are still working. the 10 year estimate makes sense because most ssds won't get worn out enough to kill the NAND. most of the stuff on an ssd just sits there. and when stuff is written, it is spread out across the nand to reduce aging.

The only time the thrashing gets noticeable on my machines has always been when the system is swapping--especially when the swapping gets out of hand. In this case, having to swap is a bad thing in general, and the fix (although it will come at a cost) is more memory. That swapping-related thrashing doesn't cause a definite and drastic decrease in the the hard drive's life, but if it were to happen on a purely SSD-based machine, it would. Hard drives really are built to handle some pretty heavy-duty work; I've put many of mine through hell over the years especially in terms of swapping, and they never failed to impress me at how long they last before breaking.

I tend to usually have a system drive and a secondary drive for /home though, so thrashing for me tends to be minimal unless the system is swapping. Years ago I put the swap partition on the /home drive, thinking that would minimize hard drive usage and therefore thrashing, but later I found that I was wrong and that putting the swap space on the same drive as the system partition gave better results.
