Apple's release of the Retina MBP, with its standard SSD drive, made me wonder about SSD vs HD life expectancies. I know that SSDs are far more durable than spinning HDs, as far as withstanding physical trauma like bumps and drops. There are no moving parts to wear out or get misaligned. But what about repeated access to the flash drive chips? I've read stuff about "a certain number of reads and writes" before even SSDs begin to fail.

Assuming that SSDs will of course fail, is this "usual" number of read/write life expectancy similar, or hopefully greater than, the average life of a spinning hard drive? I know there are lemon hard drives that fail within a month, and others that last 9 years. I'm just talking about ballpark experience.

Curious to hear anyone's thoughts. Thanks --

SSD's aren't perfect...still a great idea to maintain backups!

Great info here. Kudos to Nick for the Links.

I read them and went home and made another bootable clone of my MBP. . . ..

I've always wanted to be smart, handsome and modest. But, I guess I'll have to be satisfied with two out of three . . .
