I have seen numerous references to free space on an SSD having a dramatic effect on performance (like, every review I've ever read of an SSD...)
The Samsung 256G 840Pro I have seems particularly prone to this speed decrease it seems, once around 25% or less of the drives space is free.
I saw in passing a reference to some details written by Anand involving decreasing a partitions size, then re-partioning the freed space but not formatting it. I've tried to find that article, but can't, and can't find specific reference in the howto here. So for a very important bit of information -
What is meant by 'free space' on an SSD? I had thought that is a partition was < 75% full it was fine, or even better < 66% full. But is that what free space actually is? I'm particularly eager to know, as mentioned my 840Pro seems to suffer a lot from this condition.
I guess the next question is, if I've accidently gone over the limit, what is the best procedure to follow?
