SSD Tweaks and standard Hard Drives

[dcl]

With super/prefetch and indexing, do you have to disable the services or you can disable them specifically for the SSD? It would be a shame to have to disable them globally for the sake of the SSD and compromise performance on other hard drives.

Are people here finding that Win7 is automatically adjusting OS settings for their SSD? Thinks like disabling auto defrag/indexing/superfetch and what have you? There seems to be mixed reports.

I don't suggest disabling indexing. That is taking away one of the major improvements w/ Vista/7. Defrag/superfetch/etc are not disabled automatically.

I think the idea is that the drives are fast enough to disable Indexing and not take a performance hit?

Are most users here disabling superfetching and whatnot? Can we disable them only for the SSD so our games/media drivers don't cop a hit? Do these features even make a difference for those things?

It isn't possible to use superfetch on one drive but not the other. I personally don't think it is all that helpful anyways. I have mine setup to only cache the startup files. http://mydellmini.com/forum/windows-7/2441-windows-7-ultimate-solid-state-drive-speed-tweaks.html Post two here shows how.

If you use the start menu search a lot, w/o indexing it is considerably slower.

According to MS (http://blogs.msdn.com/e7/archive/2009/05/05/support-and-q-a-for-solid-state-drives-and.aspx) Win 7 should automatically do the following when it detects a ssd; disable defrag, superfetch, readyboost and application prefetch launching. (At least on ssd’s that Win 7 deems to be fast enough).
I thought that for this to happen the ssd would need be TRIM enabled, so I was disappointed to find out that none of the above optimisations occurred automatically following a fresh install of a retail copy of Win 7 on a G2 drive with the TRIM f/w pre-installed, using Win 7 AHCI drivers. :shrug: WTF. Did it just not work on my system or is the TRIM f/w not compatible with this Win 7 feature yet? Considering the f/w does not even auto TRIM with Intel AHCI drivers I’m going to guess that the f/w is far from being fully integrated with Win 7 at this stage :confused:


EDIT:
Weird.
"We (http://www.legitreviews.com/article/1112/2/) thought that TRIM command would run in the background without any consumer knowledge, so we asked if Intel had any documentation on when the Windows 7 ATA Data Set Management Command’s trim attribute would be functioning. For example is it set to run every hour or it is done constantly?

Intel replied that they "don't have any documentation from Microsoft on how TRIM is run. However using the Intel SSD Optimizer (part of the Intel SSD Toolbox) a user can run TRIM at a scheduled interval in Windows 7, Vista and XP as well."

So how are you supposed to know if TRIM is working automatically? The "fsutil behaviour query DisableDeleteNotify" command is only to check if OS is sending Trim commands, it does not tell you if the drive is being TRIMed.
