ide to ahci
 

Well whaddya know a question for the gang!! I am currently running win7
pro 64 on a small (40gig) ssd that was somehow set to ide on install. I
am going to upgrade this ssd to a 120gig ssd and then hang on to the
current 40gig for storage. Is there a way to purchase a new ssd,connect
it and set it to ahci then transfer windows to it? Or will this hose
windows?

First off win7 is taking all of the 40gig drive hence the reason for the
upgrade. Actual use is 37.19 total capacity and only 4.48 gigs clear.
Still not sure why it takes so much room when only the op system is
installed on this drive.

Currently my ssd scores a 7.2 on the W.E.I. as a ide drive. I know some
have said they are much better set to ahci.

As always any help is appreciated.

Drew.

Drew,
Changing to AHCI is quite straightforward, you can even do it to your
current drive right now.

1. Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\services\msahci.
2. Right click on the Start registry DWORD and select Modify.Set the
value to 0 and click OK.
3. Now the Start setting should be set to 0.
4. Reboot and enable the AHCI setting in your BIOS.
Once you are back in Windows it will surely ask for a new reboot.

AHCI performance is not the important part, it is the new features
what matter (NCQ, etc.).
As for the 7.2 rating I have observed that as typical of SATA II
interfaces.
SATA III tend to yield 7.9.
In order to get max performance you will need SATA III both on your
motherboard and your SSD.

Re: ide to ahci
 

This will enable the Microsoft AHCI driver. You will get best
performance with the up-to-date AHCI driver for your motherboard
chipset. If your chipset is new and not supported by the Microsoft
driver you must install the relevant AHCI driver before enabling AHCI in
your BIOS.

You can clone your existing Windows installation to the new SSD. Note
that you must disconnect the existing Windows installation before
rebooting with the cloned installation. If Windows sees two
installations it will decide for itself, without asking, which it will
boot from and will disable booting from the other.

There are several free, and trial versions of paid-for, programs which
can clone a Windows installation.

I have a script for that, you can download it here:

Dominic. As I just posted back to Carlos it is a older Intel D975XBX2
board. I do not think the chipset is the latest but may double check it.

Re: ide to ahci
 

Drew,
If your chipset is that old, it will make no difference in performance
between IDE and AHCI modes.
Just clone our 40GB to your new drive and you are good to go.
How long does it take to boot since you hear the BIOS beep sound?
30 seconds?
That's the best I can get from AHCI + SATA III.
Carlos

There might not be a performance difference during day to day access
now, but TRIM requires AHCI mode, and since he's using a SSD, TRIM is
probably important.

It obviously depends on the particular drive as to how important TRIM
is, with some SSDs relying on TRIM exclusively, some using garbage
collection exclusively and most of the rest using some combination of
both.

Still, given the relative lack of pain, there's no reason to not enable
AHCI.

Re: ide to ahci
 

If you have a free PCI-e x1 slot you can install a SATA III 6GBs
controller such as http://www.lycom.com.tw/PE115.htm or
http://www.highpoint-tech.com/USA_ne...eries_r600.htm.

Actually the trim function works perfectly however I cannot update the
firmware easily for it in ide mode.
