Not sure what others have seen but apparently some SSD performance disappears with time, for some brands. Samsung is named in this article but could be others as well. I have considered moving to SSD but laziness and tech concerns hold me back.
That is an interesting article. SSDs do require specific setup and maintenance precautions, since what degrades them the most is intense write operations. Being aware of this and researching how to properly set one up is important for longevity.
I got a Patriot Wildfire 240GB four years ago and just reformatted/rebuilt this machine and benchmarked it after it was fully loaded. It has slipped about 10% in 4 years, but is now on par with its benchmark (was faster then).
One thing of note is that excessive heat (same as the excessive writes) will degrade electronics more quickly, so a "laptop" application will see even more heat (mine is in a desktop). This would also be something to consider with using one, but the read/write speeds of pretty much any SSD will put a HDD to shame - no moving parts.
I did find it interesting that none of the Samsung 850's were mentioned in that article. Another interesting item is that the smaller (128/256) 850 EVO outruns the 850 PRO (I thought the PRO was the top of the line model, but not looked at Samsung in a while).
