the problem is when i first benchmark the score... the write read speed is 460mb and 190 write... now is 460read 150 write... how come decreased?

"Used" SSDs are always a bit slower, because the NAND chips they use needs to erase "old" data first before they can write new data. Benchmarking a lot will quickly render any SSD into a "used" state. Especially with CrystalDiskMark's default setting of writing about 20GB of data per full test.

so isit normal for intel ssd 520 120gb going on 150mb on write speed?

That I do not know. But I would recommend that you do at least one test run with ATTO first. If it should still show ~150MB performance on write, then there might be a problem.

ok will try now

Looks like everything is fine then. Read and write is hitting past 500MB/s.

This is how Sandforce-based SSDs behave. Poorly on random and incompressible data and very well on compressible data, and all the manufacturers uses the compressible data performance for their advertising.

phew... i thought got problem thx everling for the software

You're welcome.

How come mine m4 doesn't show in hwmonitor??

Nor does mine and nor does every single owner of the M4.
SSDs don't have a temp sensor like HDD does, because there's no use in it having one. An SSD doesn't even bulge 10 celcius anyways.

So nothing to be angry about, it's just the way it is. Don't freak out because you think there's something wrong with your SSD when there isn't.

Normally I just do a diskpart and "clean" it. Works like a charm for me and I regain the speed You can try it too.

Crucial M4 128GB user here...
my cpu only QuadCore Q8300
8gb ram...ATI 6970
very happy with performances ....
cant imagine with i5 cpu and 16gb ram
and run SATA3...now only running SATA2

Salam.
A new noob reporting in.

my intel 330 120gb. dont know if this is good or not.
my 1st ssd and still a noob.

result after doing ssd optimization step ( i refer to link provided on the first page ).

Thanks for the tip!

I also use diskpart and "clean" my SSDs, but my goal was to configure my partitions. I hadn't thought about using "clean" for restoring performance. I should try that one day on my old Kingston SSD as its benchmark performance has dropped over the years.

The performance doesn't seem to be improved.

Is there any other guide for optimization?

New build with SSD (120GB). Should I partition it? Or just leave it like that with OS & some applications...

All sifus ....120gb ssd issit enough for win7 64bit + 1 antivirus software? any reliable brand can suggest? Intel?

no need partition.... trust me, you wouldn't want a partition on a disk with small capacity...

Not all optimisations will improve raw performance. Disabling the automatic defragmentation for instance doesn't effect your raw performance, but it does improve your SSD's lifespan.

You do need to create at least one partition in order to install the OS. As for having multiple partitions, don't create them if it is in a desktop and you have HDDs. If you are on a laptop, you could create them if you like. My laptop's Windows 7 64-bit partition was only 40GB in size until recently.

120GB is more than plenty, like I said above, 40GB is spacious enough for non-gaming needs.

Intel's 330 Series is a good SSD brand for anyone new or old to SSDs. They're cheap, fast, and reliable.
