TRIM need AHCI or not

[pcslookout]

Ok I really need to get this question officially answered. I found anandtech saying you can use IDE or AHCI drivers to get TRIM. Then here is someone else who says the same thing. I know this source isn't the best like my first one but still. http://communities.intel.com/thread/8243?tstart=0

 

[Mr.Wolf]

I'd like to know if you have NCQ enable in your win7 in IDE mode?
Maybe you can use crystaldiskinfo to see if it's enable.
Tkx.

Checking now.

Ok this is my first time using this program. How can I make sure to see if NCQ is enabled or not please? Going to check if TRIM is enabled as well just to double check.

Ok here is a picture of what it says. Yep I have the latest pulled Intel firmware working just fine on the drive.

TKX.
In "supported features", we can see It says you have SMART, LBA, NCQ and TRIM enable (they are highlighted).

If you press your D : or E: drives in teh above screen u posted, and they are not SSD, you'll see that trim will be disable and other features will change.

Now you should do a benchmark to see if your ssd is top performance
try "AS SSD benchmark", I get a total score of 418 in my x25-m g2 160 gb here. (intel g2 80gb should score lower than 160gb)

If you get much less performance, try to run intel SSD optimizer from "Intel SSD Toolbox", and re-run the benchmark.

The only way I know to test if trim and ncq are working is comparing benchs with drive reviews.

Wow my scored bascially doubled by enabling AHCI from 196 to 401 The whole drive feels a lot quicker too. Can't believe it can double my performance like this. Now I have a few black ! with yellow circles in my device manager though. Not sure what to do about that. Glad I was able to enable AHCI though without a blue screen or my BIOS getting stuck. Maybe I will finally see the speed difference everything is talking about with SSDS. Maybe this was my problem all the time. Just that Windows 7 64 bit installation refused to finish or even start at times when AHCI was enabled. Sucked. Glad to know those hours weren't wasted though trying to get it to work.

Oh yeah I used F13 BIOS for my Gigabyte like you said because the issue with a pc not even booting up pass the BIOS with F14 when AHCI is enabled happen to me as well. I really prefer to use F14 because it has a new motherboard flash feature where it saves your last motherboard BIOS to your hard drive so if your flash goes wrong you can recovery your BIOS and save your motherboard. Oh well when I feel like I need another challenge I guess I will upgrade to F14 and try to get AHCI working with it maybe. Not sure if I want to break anything though.

Nice. However synthetic benchmarks for disks rarely give any real-world performance indications unless all you do is random read/writes or sequential read/writes, which in the real world, you use both.

AHCI/IDE, only difference is the first support NCQ/hotswap plug. My question is does desktop Operating Systems support NCQ? I also though this was a server Operatin System function only.

From a quick google I did a week ago on AHCI, NCQ does work on a desktop OS and I believe support goes back as far as XP.

I also thought AHCI also allowed APM and maybe AAM too.

1. TRIM needs ahci
2. AHCI enables NCQ, which would increase your SSD performance even without TRIM.

TRIM only requires the ATA stack to pass TRIM commands (including the drivers), be it IDE mode or AHCI. How TRIM cleans blocks is then down to the controller and firmware in the SSD.
No RAID drivers allow TRIM at the moment.
