I Recently had a quad 6600 and a AMD 5550 card HTPC with Windows 7 Ultimate 64 bit 8Gb Ram and media centre was snappy and responsive. Op System was on a WD Green drive and media library on a second WD Green Drive.
I Just built a new HTPC with Haswell I5 4570 wth 8GB Ram no video card but have added a ssd for the op system still W7 Ultimate. Im still using the same WD green drive for the library.
My Problem is MC is laggy when changing between shows. After deleting a show or changing between folders. The whole thing freezes for about 10 seconds or more and there is nil response then it works again. All other software is exactly the same as the old rig but there is a problem somewhere.
My Readings suggest a separate Video card would eliminate this but the new chip on the Haswell is supposed to be much better for HTPC than the old one. Can anyone shed any light on this laggy problem.
Also if you cloned your OS, instead of a clean install check SSD alignment: http://whirlpool.net.au/wiki/Checking_SSD_Alignment
Also verify that BIOS is set to AHCI not IDE. I doubt this is the cause but what Antivirus are you running?
Last - check eventviewer for any error messages or related warnings.
I did a clean install of the op system on the SSD I have just noticed that the Green drive with the Shows on etc is listed as an extended partition under Administrative tools so Im wondering if this is causing me trouble.
I checked AHCI and SSD is working as it should.
I will wipe the data drive reformat it and see if that helps.
