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.

Do the maths. 3000 p/e cycles per block. So for a 128GB drive with ideal wear levelling, you can write ~3000 * 128GB. If you write 64GB a day (unlikely) you'd get 6000 days worth of writes. That's > 16 years.

I believe they "did the math" as well as controlled-climate testing when they came up with the conclusion that the Compact Disc would last up to 100 years, did they not? Also, I've had a few hard drives outlive the computer itself, so that's not saying a whole lot about the SSD. Especially when it's all theoretical anyway.

And in the previously mentioned case of swap use on an SSD, that same math will work out of your favor, speeding up the loss of bits on that device. Unless these drives actually swap bits from different partitions across the entire device. Do they?

Once these things have been in decent use in the real world for about 15-20 years and there is real-world evidence to back it up, I'll believe. ;) Of course, by then the newest SSDs of the time will undoubtedly be far more reliable than what there are now.
