Sorry about that. I will try to be more clear using an example. If you have a new SSD or a secure erased SSD of 100 GB, and create the partition of 90 GB, the balance of 10 GB will be ignored by your OS and be available as manual OP. Thus when you open My Computer in Windows it would show a drive with 90 GB capacity. Alternatively, if you went into Windows and shrank your existing partition and did not format/partition the new space created, it would qualify as manual OP.

...

The "hammered" mode occurs when the garbage collection/trim process cannot build clean blocks and additional writing to the SSD forces use of blocks that already contain data. In this case the SSD has to read this data, store this data, clean the block/blocks, and rewrite all the data (old and new) to the now clean block/blocks. You can see how complicated and slow the write operation now becomes. Here again the size of the OP can help in deferring this stage.

A secure erase to the drive in any one of the above states, allows a fresh start with all clean blocks. At regular but distant intervals, this is an excellent way to freshen up the SSD and while it will impact the overall SSD life by bypassing the wear leveling approach, it is not believed to be significant.
Very well explained, dererved rep.

I thought my friends here already knew this.....

Leaving the new reserved section "unallocated" was what I didn't realize.

I never found it specifially stated unallocated space so I thought it was just a partitioned area.

Which made no sense since Windows was in control of the partition so how could the SSD use it as Reserve.

Now it all makes sense by adding one word- unallocated.
One of those things that get you stumped and after the fact you go "so simple"!!! <Double face palm>

Ya, happens to me all the time

I searched for the above explanation for a long time before I found a good simple answer.

What's the bottom line on this idea of over-provisioning??

I have an 80 GB SSD with a single C partition covering the entire drive. Windows shows it as 74.5 GB total capacity.

I take that to mean that I have 5.5 GB of unallocated space available for "over-provisioning".

Who is to say that is not enough unallocated space? If I need more, how much more and how did you arrive at that number?

Does the need for additional over-provisioning unallocated space apply to ALL SSDs? Only certain SSDs? Which? With which controllers?

More clarification on these points requested.

Intel 320 series as you and I have don't need over provisioning for GC/Garbage collection.

Install the Intel SSD Toolbox and run manual TRIM command once a week and you are good to go.
That is all I do with mine and is all that is needed.

Older Intel X-25 series and most all of the other brands and series depend on auto TRIM and GC so the over provision is useful.

I run Windows Disk clean-up and clean out the temp files then run TRIM thru the Intel Toolbox every 7-10 days. It takes about 2 minutes total for both operations.
Of course if you use one of the other apps to clean out temp files that is okay also.

So install Toolbox and enjoy your SSD!!!

Mike, The X25's use the toolbox also. I just schedule mine to run once a week. It runs automatically.

Thanks Essenbe.

I wasn't sure when the Toolbox started.
