Might want to consider browsing using something else (a large tablet e.g.?) until this issue is resolved. My machine is almost identical to yours. My reported writes are about 1.31TB or less than 1/40th your number. I do some native compiling and some browsing. Chrome is a well known memory hog.

I haven't even installed Chrome on this laptop. I switch between Safari and Firefox.

I wonder if Chrome's memory usage pattern is a contributing factor.

wtf, 55TB+ read/write in 2month? what the heck are you doing with your laptop?

This is my 11y/o SSD ( OCZ Vertex2 64GB ) on my laptop:

241 Lifetime_Writes_GiB 0x0032 000 000 000 Old_age Always - 3904

242 Lifetime_Reads_GiB 0x0032 000 000 000 Old_age Always - 5120

Did you even read the headline? I mean, it's kinda what this is all about.

I had a ridiculously high failure rate with the Vertex 2. I also still an OCZ drive of that era somewhere, which would work... But if you didn't use it for a while, it would be completely blank when you next used it.
