[SandForce OPing] Does manual OP an Intel 530 yield benefits?

As above. I am not familiar with Intel or SandForce drives. I'm in the market for an Intel 530 for a new laptop and I'd like to know is it true that SandForce drives can s imply use spare area that isn't OP'd for TRIM, GC etc? i.e. 100GiB/240GiB used, can an Intel 530's controller access the remaining 16GiB+140GiB?
That said, I tend to run my SSDs no more than 50% filled and the Intel 530 will operate in a similar environment.

Simply for the space that's unused, I OP them as with the Samsung drives seen on my sig so on average, my drives are at least 40% OP'd. I only run consumer workloads.

If there are specific articles or tests that prove or debunk manual OPing benefits on SandForce SSDs, do post up the relevant links here.

Cheers.

 

Ahhhh.... You my friend have opened up a real can of worms since none but the ssd engineers can answer this. For all its worth, I have heard from quite a few it experts that the unused partition is just as good as manual Op on modern SSD. However, the most reliable method is still making a smaller partition than the drive as the Op will still stand even as the drive is completely filled under continuous load. This is especially important for SandForce which aggressively uses spare area for GC and to improve performance as it doesn't have a dram cache.
