Filling up a SSD and what problem to expect

[jfri 11]

I have read on support forum for vertex SSD that you should never fill you SSD more than 80%. I wonder why? What problem can I expect if filling it more? How much do you fill your SSDs?

Mine's been at 90+ percent pretty much since I got it and haven't had any issues.

I'm no expert, but I think the garbage collector needs some free space to move things around. It's not a mech drive though, you should be fine up to 80 - 90%Nick Needham recommends 90% maximum

The wear levelling firmware needs some storage to work, but if it needs all of 20% for that they're doing something wrong. The Intel SSDs maintain some background storage not reported or user-accessible for this purpose...perhaps others don't.

I think I have read somewhere that this generally apply to SSD. It might be pointed out that my 120 Gb SSD was noticable cheaper than others similary SSD and the seller told me not as fast either (but the price has been raised now).
