This is one of the best, most effective upgrades I have given my laptop and has extended its life by at least a year or two. Considering that I go through high-powered laptops every 2 years, this is great! I bought the 1TB version and have not regretted it for a second!
The magician software which ones with the disk is not optional if you want your drive to stay at top performance. Not only does it tweak your windows settings to disable anything which is physical drive-based, but is also keeps the drive working at top performance and after spending all that cash, this is something you'll want to do.
Like other reviewers, I have not turned off indexing and that will shorten the life somewhat, but I suspect that it will last as least as long as any laptop drive - if not longer. I will certainly be taking this drive along with me when my current laptop is finally confined to computer heaven.
Bottom line: if you want to purchase an upgrade that will make a real difference to windows/mac/linux performance, then this is the upgrade for you.
