How to enable AHCI in Windows 7 after Instalation:

There is one way to fix this, although you need to have knowledge of registry editing. The detailed steps from Microsoft are as follows:

1.Exit all Windows-based programs.
2.Click Start, type regedit in the Start Search box, and then press ENTER.
3.If you receive the User Account Control dialog box, click Continue.
4.Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesM sahci
5.In the right pane, right-click Start in the Name column, and then click Modify.
6.In the Value data box, type 0, and then click OK.
7.On the File menu, click Exit to close Registry Editor.

After this you’ll have to restart your computer, go to BIOS and enable AHCI. When you log in to Windows again, you’ll notice the installation of drivers for AHCI. Another restart will be required to finish the driver installation.

These steps are provided at your own risk and not suggested unless you know and understand the risks. You will want to make sure the controller driver and MB BIOS support this option before you enable it.

Mám zapnutý, SSD nevlastním.

Diky Karle,
pak se tedy obavam, ze to neresi, to zda je TRIM aktivni, pouze to rekne, ze je zapnuty. Chapes to stejne? Nebo to mam povazovat za aktivni?

Já se tím nezabýval, třeba tady píšou:

TRIM only improves performance when you delete files. If you are overwriting an existing file, TRIM doesn't help and you'll get the same write performance degradation as without TRIM.

Takže asi nejlepší metoda je mazat něco velkého a měřit čas :)

Neco bych tu mel, ta slozka se jmenuje Windows :)

tak me napadlo, neexistuje pro Samsung nejaka utilita, ktera by se dala jednou za cas ruco spustit a mela by stejnej efekt jako TRIM? pripadne by se jeste hodila nejaka, ktera by dokazala analyzovat stav toho disku. po delsim uzivani by se pak dalo rict, zda je trim aktivni ci nikoliv
