I thought it would have been kind of defragmenting.

The files at a SSD are major fragmented. Yes, this is good. Ignore this.
 

Whatever OS can access the "fragmented" table and thus execute TRIM on that.

I don't understand this.
No OS can "fragment" the SSD internally.
Only the SSD firmware can access the blocks inside the SSD.
 

GC

This is SSD firmware internally too. No OS is involved.
 

Still, if 7 doesn't see the XP partition will it be able to do the GC?

It's OS independed. Yes, GC is active.
 

The interesting thing is that what the Magician Software seems to do is an on demand TRIM, if that is so, then TRIM is not a real time thing at all, and the data to be trimmed must be hold somewhere (SSD?) meanwhile, in that case my theory would apply.

TRIM is real time issue, if the OS supports TRIM: Windows 7
In addition you may TRIM on demand using the Magician Software: Windows XP and Windows 7

Real world advice:
ignore TRIM theory. You may measure a difference, won't recognice one in real world.
Use the SSD and be happy.

But if TRIM is a real time task (ie. when files are handled), what is an on demand TRIM supposed to do? It is passive (real time at background) or active (on demand). If you can execute TRIM on demand through software, it would well accomplish the same goal through 7's internal (and automatic/passive) TRIM, don't you think?

It's real time on demand.
Run Performance Optimizations on demand, the software trims at real time next: runs some minutes
Most likely the Magician Software crawls the NTFS MFT and calculates unoccupied blocks.
And informs the SSD firmware: this blocks are free to use

Yes, I think so.

Contrary there are other user experiences
http://www.anushand....840-series.html

http://superuser.com...sd-optimization

Windows 7 is supposed to run the TRIM command automatically, but when I run the performance optimization in the Samsung Magician software, I see a vast improvement especially in random write operations (up by 30-40% immediately after optimization).

Performance Optimizations seems to be useful at Windows 7 too.
I don't know what Performance Optimization does actually.

Again: you may measure the difference, but won't recognise this at real work

I see, so the "Performance Optimizations" actually "do things" that either XP or 7 don't. So at practice using XP or 7 is indifferent for the end user.
This SSD technology seems rather immature still, nobody knows what really is what and what should be done, actually I could say the same about computers. It looks like a giant mess of great and sometimes not so great ideas that somewhat made their way to surprisingly function together and not break apart.

 

You said that what Performance Optimizations does is run some minutes being TRIM aware, so it's more a kind of prevention than say "fixing".

But the next quote says that after applying Performance Optimizations the SSD runs 30%-40% better, kinda fixing past degradation.

As for a average end user it's pretty fine. Given a decent SSD, use it and ignore technical details.
It runs smoothly in real world.

No, it's fixing some previous glitches.

No, not the SSD runs better at all. A special feature works better.
Value this feature for daily work: random write operations are seldom at a average end user.
A average end user won't recognise any change.
You have to decide at Windows 7 with TRIM: it's worth to run Performance Optimizations at all?
Why take the time, if there is no real benefit after?

Just my 2 cents worth:

Get on another computer and go to:

http://www.partition...ootable-cd.html

download and burn the free iso to a CD. Use BurnCDCC v2.02

http://www.portablef...ndex.php?id=116

With ONLY the SSD attached, have your computer boot from

CD 1st.

When it loads, right-click the SSD and partition it to your liking.

My Corsair CSSD-F120GBGT-BK is C 35GB, D 16 and E 62.

Now right-click the C and set to "Active".

Shut down.

Restart and put your Win 7 DVD in the player.

Install to your C.

Reboot and take the DVD out of your player.

Good luck.

B

BTW: Win 7 64-bit has built-in Trim.

To see if TRIM is enabled, open up a command prompt

and type “cmd” into the search bar.

Right-click on the first result (“cmd”) and click

“Run as administrator”. Next, type in the command

“Fsutil behavior query disabledeletenotify”.

Hit Enter. If this returns the result “= 0″,

you’re good to go! Otherwise, TRIM isn’t

supported and needs to be enabled.

Try entering the command “fsutil behavior set

DisableDeleteNotify 0″. If that doesn’t help,

a firmware upgrade might be necessary to enable TRIM.

You need nothing extra Win 7 bootable disk can handle everything.

When you get to partition screen create 1 and it adds the small one.

Select 2nd partition and choose delete. Now just Extend the 1st part to fill drive. Format and install. Or just choose next and Windows will format it and install

No 100mb disk

 

On Win 8.1 its 350mb
