My descovery made for increasing the normal s-ata hdd performances for the VAIO Z series...

In this topic I want to gather all the possible informations about how to speed up a normal s-ata HDD.I have a Sony VAIO VPC-Z13A7E which has a normal s-ata Toshiba HDD with 5200rpm (it's sad but it's like so..),and I've begun to make some studies about how to raise the performance of this type of HDD and I had also made some tests with some different size of cluster .First I had made a partition with 64k cluster (the maximum cluster size for a NTFS partition) which it wasn't so easy to do it the speed was amazing but had some incompatibilities with the software,after I tried to make a partition with 4k cluster (the maximum cluster recommended for Windows 7),in this one I felled a big difference comparing with the other one with 64k but this one had a incompatibility with the nvidia GC given me a error code 31 and a exclamation sign right next to her (like in the first photo) i tried to find something about this error but found nothing concrete.And with the 4k cluster it freezes allot of times also.Conclusion is that changing the cluster size can improve the performance of the normal s-ata HDD and this i had seen also in the system rating made by windows at the hdd section for the disk data transfer rate the score has significantly increase,i also post a picture of the system rating with 4k cluster in which the 4.4 pt are because of the GC error 31,and i'm sorry that i didn't made a print screen also for the one with 64k cluster...
PS:Sorry for my bad english...
