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. :)
