Makes multiple references to "mandatory" over-provisioning on the 1TB 840 EVO, for example:
"Samsung’s 3-bit/cell MLC-based SSD 840 Series, equipped with mandatory OP, will still far outlast the useful life of the hardware it powers."
They go into no explanation about what "mandatory" means. I am not sure if the drive has inaccessible space allocated behind the scenes for OP, or if they mean that the user must allocate a mandatory minimum amount of space.
In Magician, OP is currently disabled, and I have no unallocated space. Effective drive size is 920GB (out of 1TB; ~9% presumably used by spare block pool). For the 1TB drive (which, from what I've read, has different characteristics than the smaller drives, and so answers pertaining to 256/512GB drives may not apply here), do I need to manually set aside OP space, or is the "mandatory" overprovisioning Samsung talks about already allocated?
