Windows 7: AHCI : Enable in Windows 7 / Vista

I'm not entirely sure case. I didn't bother mucking with mine, and its running sweet as.

Case and Golden,
Some of the tweaks given at many SSD sites are for Gen1 SSDs and my not be needed for Gen2 SSDs.

Here is an OCZ thread dated after the thread you linked talking about this issue.

As mentioned, if you want to change settings and experiment, tweak and/or play with the settings, by all means do it.

The above quote just says that it's not required and may not give you any noticeable improvements.
It's up to you if you want to do most of these tweaks.


Case, the easy way to check your firmware is to D/L AS SSD, you don't have to run it, in the upper left corner just under 'Intel' will be the firm ware version.

Not sure if someone said this already in one of the 31 pages, but the performance increase is very noticeable. When moving files around 1.5GB it would start around 46MB/s and slow down more and more till the end it was about 18MB/s. Now with AHCI enabled it starts around 60MB/s and doesn't go below 33MB/s even with much larger files. So it's almost twice as fast...

I think a few people have mentioned things like this here and there (including me), but it seems you'll get a more noticeable performance gain if you have a drive that's had any fragmentation on it. The NCQ features of AHCI / RAID help a lot with reading (and I assume writing) to fragmented drives.

I have a theory that even a drive that was fragmented at some point and now no longer is can see a performance boost... The defrag process simply file fragments so each individual file is either not or at least less fragmented. But that doesn't necessarily mean that all the files in a folder are in one section of the drive platter.

By that, NCQ will help with reading a series of files that are on different areas of the drive platter more efficiently. Then again, that is just a theory and I may be horribly wrong, it's just my opinion.

For whatever reason, AHCI can help boost access speeds of almost any decent drive.

Well said!

Agree with both of you

Hehe... Thanks guys.

Hi,

For those of you have turned OFF disk indexing on your SSD's like me, be aware that I have run into problems with arranging files in Libraries because of this.

So, if you make extensive use of Libraries and you have an SSD, you may want to reconsider turning off indexing, or coming up with an alternate strategy. I'm still trying to work out what to do.....

Here is a link to my original post about this - rep to Brink for confirming the issue:

Library Question

I'd hazard a guess that the issue you described would probably affect normal drive users as well... Disabling File Indexing would affect how Windows handles the files themselves, it makes sense with the libraries if you think about it; a library in Win7 is essentially a dynamic folder, so sorting data in that dynamic folder without having indexed information on hand would be pretty impractical. If MS did still allow it, it would be dog slow and definitely not worth doing.

I also use the libraries a hell of a lot on my PC, mostly because I've got too much Anime / Movies / Series to fit all into one folder, so I use libraries to make it easier to make my "Media", "Data" and "Install Files" folders easier to find and use.


Hmmm.... I'd better stop there before I start going off-topic with crap like folder sharing with libraries. Lol.

Hey Zalith : is that on an SSD out of interest?
