C300 on SATA3 TRIM issues

danielanthony · 20 Aug 2010 at 07:24

I liked the look of the C300 256Gb SSD drive until I found out that it would not support TRIM when using the Marvell SATA3 controller:

http://www.forum.crucial.com/t5/Sol...vell-9123-9128-TRIM-yes-no/td-p/11109/page/16

I think this issue should be wider reported as yes, the drives themselves support TRIM but these instructions are not passed by the controllers they will be plugged into.

If there is a solution to this, getting SATA3 with TRIM working, I'd be interested to hear it! Is it ever worth buying an SSD drive without TRIM?

you would be better getting the aus usb3 pci card,i used this card with a 128gb c300 and was getting full read/write 355/140,it also has trim

That debate goes on and on. Just use the standard MS AHCI driver for Trim. C300 on Marvell SATA 3 controller:

Think you will find that the controller on the U3S6 is in fact the same one as is on his motherboard so this will not work (9123 or 9128 doesn't really matter, they are both marvell)/ you misunderstood the ops situation

The Op needs to uninstall the marvel drivers and go back to the MS ones that come with win7

I have the asud card and I use the MS drivers for Sata 3. I can install the Marvel drivers but get no trim with them. I hop marvell come out with drivers with Trim support soon as I get better performance with their drivers then MS.

simulatorman's results look pretty good for non-specific drivers on that controller. We have the same mbI believe so even more relevant.

Surprised Marvell haven't sorted this out themselves :-|

So how do you switch to the MS drivers if the C300 is your boot drive. I read somewhere that it's as simple as going in and going to device manager, click on the controller and say Update driver and then just pick the "Standard AHCI 1.0 Seial-ATA-Controller" instead of the "Marvell 91xx SATA 6G Controller".

Has anyone actually tried this out?

When I tried out the Marvell 91xx SATA 6G Controller Drivers and decided to go back to using the MS drivers, all I did was to uninstall the Marvell ones
from device manager, rebooted the computer and during windows 7 loading up, the MS drivers where automatically installed.

Yeh you just going to device manager, click on the controller and say Update driver and then just pick the "Standard AHCI 1.0 Seial-ATA-Controller" instead of the "Marvell 91xx SATA 6G Controller". When you computer restarts it start using the other drivers. I use the MS work for a week then switch back to the Marvell one as the performance is great with the Marvell drivers.
