Intel X-25-M

Hello, do i have trim properly working?

I installed this one today, it already come with latest firmware, so what i done:

1. Set Bios to AHCI
2. Clean Windows 7 install

Once i got in desktop, i saw that it was listed under "Safely hardware remove", why?

I tryed installing latest chipset inf, but it was still showing there.

Then i download intel rapid storage technology and finally it is not there anymore.

What worries me, if by having this installed, will trim work? i read that it will not for raid setups, but with only one SSD, what?

This is normal; you did not need to do anything else. AHCI natively supports hot-swap, so it's normal to see the "Safely Remove Hardware" icon when running drives in AHCI mode.

There's probably no harm in installing the latest chipset drivers (although it's likely unnecessary) but there is no need to install the IRST drivers unless you are running drives in RAID.

The good thing is, your drive will work either way. But I'm not sure if its performance would be better under the Intel chipset drivers or the IRST. I prefer to use the Intel drivers for my chipset (ICH10R) since I'm not running RAID; I haven't seen the need to run the IMSM or IRST since Windows XP.

If it is normal to be shown there, then why with irst drivers it dont?

Thanks for your reply.

there is a way to check if trim is working in this post. you might wanna read it anyway because it has some interesting facts

if i remember correctly i think you type in "fustil behavior query disabledeletenotify" into command prompt. if it give you back disabledeletenotify=0 then its on and working. however i still run intel's trim tool every once in a while

The command is not a reliable way to tell if TRIM is working or not. It's reported that TRIM was on when I was using an old JMicron drive which had no TRIM support what so ever. The only reliable way to tell is to use your drive for a while and see if you notice any performance degradation.

If he's using the default Microsoft AHCI driver with newer firmware, than TRIM will be working. There's no reason to doubt that as I've never heard of it not working when those simple conditions are meet.

There is seriously no reliable way to know if TRIM (a much touted and apparently beneficial feature) is enabled on Intel SSDs? I find this very unreasonable.

The command line utility -> tells you if Windows 7 has enabled TRIM.
AD SSD benchmark -> tells you which driver you use; either msahci.sys or recent iastor.sys (intel) have TRIM
finally, CrystalDiskMark -> tells you if your SSD supports TRIM

So no real way of checking of everything works, but TRIM has to be enabled on three levels:
- filesystem (windows 7 with disabledeletenotify=0)
- driver (msahci.sys on windows 7 or recent intel drivers)
- SSD has to support TRIM

Note that the controller itself shouldn't matter, as long as it's AHCI or IDE compliant (thus no RAID/SCSI/CAM).

I meet all of these, so i guess trim will be working... but i dont understand why with windows driver, ssd is shown in "safely remove hardware" and with irst ones not...

Current benchmark:

On average, good or bad?

Looks fine to me!

About the 'safe removal' that's the 'hot-swap' feature. It's possible the Intel drivers hide the system disk in this list; while the Microsoft driver does also list the system disk; which may not make much sense since disconnecting the system disk would crash Windows.
