Running Intell SSD in legacy mode with built-in windows driver: Any performace issues

Hi

I'm considering a X25-M G2 80 GB drive in my next system. I'm aware of the problem with missing TRIM support in Intel storage driver (which I find rather embarassing for Intel...). I'm therefore wondering if it has any influence on performance when running the controller in Legacy mode. I'm assuming that native command queing won't work, but does it make any difference on a SSD where the penalty for random is so low?

Thanks in advance
 
Windows 7 I assume? Why wouldn't NCQ not work? If you are running the MS AHCI driver, NCQ should work (AFAIK). As for performance, not sure. I know that Intel is supposed to be working on a TRIM compatible version but not sure when it's going to be released.

I thought legacy mode would force IDE/ATA protocols; there's no NCQ in IDE/ATA. Please correct me if I'm wrong, I don't want to spread misinformation.

AndyKH why are you running SATA in legacy mode btw?

NCQ according to Intel is supposed to help compensate for latencies in the host PC, rather than sending one request at a time multiple are sent to the drive without having to wait for a response.

Oh, you're right. I thought he meant native MS drivers vs "insert other brand here" drivers. Never crossed my mind about legacy = SATA non AHCI. Sorry! 😳
 
Thanks for all the replies

Yes, why?

I apparently misunderstood something in an article i read. I realize now that AHCI mode is exactly the opposite of legacy mode. So I have absolutely no intention of running in Legacy mode. I will just do as the article says: Enable AHCI mode and install Windows 7 and then refrain from installing any storage driver and just let windows use its own.
 
You can run in IDE (legacy) mode, AHCI (native SATA) or RAID mode. Pretty straight forward if you ask me. You'd need AHCI to enable TRIM access and also command queueing for the SSDs, which intel uses.
