How much percent do you over provision your Samsung SSD 840 Pro?

What is the consensus on this?

Exactly 0%

LOL, seriously? so what's all this hype I read about over provisioning and that its the magic of Samsung's software?

PS: When I was speaking to Kingston Tech Support about my previous HyperX 3K SSD 480 GB they told me no need to overprovision as the SSD itself knows how to handle this

All SSDs handle this themselves, you don't need to be messing with overprovisioning unless you know you need to.

this. SSDs have improved a bit in the last couple years.

I understand, thanks for the advice guys

I over provision about 20%. You can also not fill up your drive, but I think partitioning makes it easier. If your SSD is full, its performance goes down and isn't consistent.

Anand recommends 25%.

From your link:

It's because of this relationship between write amplification and spare area that we've always recommended setting aside 10 - 20% of your SSD and not filling it up entirely. Most modern controllers will do just fine if you partition the drive and leave the last 10 - 20% untouched.
