Thanks for the feedback guys. There is a new Revodrive3 X2 Max IOPs that coupled with the right system that should have amazing results. Presently difficult to get hold off.
What I wanted to point out in the post, was the benefits off building in extra manual OP when initially installing Windows on SSD drives. I have been using SSD's for a considerable time, Intel, Crucial, OCZ through their several generations and in practically every case, creating approximately 15 to 20% manual OP makes a tremendous difference in the garbage collection (particularly important in raid setups). When necessary it is a simple process within Windows to access this extra OP for traditional storage by expanding the partition. Furthermore, the garbage collection process can be greatly facilitated in heavily used SSD's by logging off the computer in the safe mode. In this mode the reduced CPU and disk activity greatly improves the garbage collection process.
Cheers.

OP- Over provisioning free space.
Never made sense to me because the factory over provisions SSD's out of the box.
What good an extra partitioned non used area would do is beyond me.
It isn't a fixed partitioned area as on a spinner.
I'm not sure if it helps but have never read any proof that it accomplishes anything.
I live next to Missouri which is the "Show me State." Still waiting on a credible explanation in English not jibberish.

As Hopalong X mentioned, OP refers to over provisioning. A little explanation might help.
When you first get your SSD you will notice that the actual capacity shown in Windows is a little less than the stated size of the SSD. The difference (which puzzles some first-time SSD owners) is the part of the SSD drive allocated to OP by the manufacturer. The garbage collection and wear leveling algorithms built into SSD drives used this OP to assist in their processes.(if you need more information on how this OP is used, please post) They obviously try to achieve an optimal OP between efficiency in their algorithms and available capacity.
When the user is installing the OS on these SSD's they have the option to create a partition/partitions that do not fully utilize the available capacity. Any differences between the partition/partitions and the available capacity is referred to as the manual OP. By creating this manual OP, the efficiency of the garbage collection process can improve. Since very few users maximize the use of capacity, at least initially, leaving certain space unused is fairly easy. Recovering the space if and when needed is also easily accomplished by increasing the partition size within Windows. In raid setups, trim is not available to the SSD's and they have to depend on efficient garbage collection to maintain their speed and efficiency. Creating manual OP can greatly facilitate this process. It also helps in drives where trim is available, keeping in mind that trim is simply an instruction to the SSD and it is the garbage collection/wear leveling process that accepts the trim instruction.

That is the most sensible explanation I have seen of over provisioing.
Speed up clear/clean garbage collection would increase speed overall the more you use the drive.
Intel doesn't use GC and the newer ones have manual TRIM available thru Tool Box.
So I have not run into this problem- yet.
If I get a Crucial m4 now it makes sense of why to over provision!
Thanks.

1. For that reason some manufacturers sell 60GB SSDs which are in reality 64GB SSDs. At least they are honest.When you first get your SSD you will notice that the actual capacity shown in Windows is a little less than the stated size of the SSD
2. Another effect is, of course, between the decimal number on the box and the binary number in the system.
