C300 Stuttering

Hey everyone,

Have a 64GB C300, stutters when playing media files. Latest AHCI drivers, running off T61 (ICH8M), with updated SATA II bios. Tried turning off AHCI power management, but none of the common wisdom for SSD performance during "idling" situations seems to apply. Sometimes the stutters are very long lived. Up to 30 seconds. Any ideas?
 
Just to clarify this is clearly an SSD I/O issue. While HDD is relatively idle (like during movie playback) hard drive led will randomly go solid for up to a minute. Happened today while watching netflix. It's absolutely unfortunate, because the SSD is pretty nice. The problems did not manifest with a Sandforce based SSD, although I did not do extensive testing on my Sandforce drive since it perma-BSOD'd on me about a week after install (boot drive). The problem is supposed to be down to AHCI power management, but I've tried disabling it using regedit and so far the problem has not disappeared.

No one has had this issue? 002 firmware btw. 006 introduces random i/o stutters for people.
 
Try this: Go to Device Manager, double-click on the C300. In the new device properties window that pops up, click on the Policies tab and ENABLE "enable write caching on this device" AND ENABLE "turn off windows write-cache flushing ..." Now reboot.

Has seemed to work to fix stuttering issues with 06 firmware and certain Intel AHCI drivers.
 
I will give it a shot again, although I did have that setting enabled before, with no difference, though that may have been before I messed with the AHCI power settings.
 
Damn.. now I got this problem with my brand new C300.. I guess it's my punishment for not waiting for the C400 to come out.

...starts looking for solutions and trying them out....
 
Have you changed the power management settings on your computer to always on?

Some laptops come with proprietary programs and some use the OS's program but they must be set to always on.

My 2 x 128GB C300s in my desktop have the 0006 FW on them and I have NEVER experienced any stuttering. I would try any of the suggestions here but moving to 0006 FW may also fix your issues.
 
My C300 is brand new, with the 0006 FW and all. It still stutters once in a while. Event Viewer shows "The device, \Device\Ide\iaStor0, did not respond within the timeout period."

I tried that. It didn't work.

Try disabling C6 reporting in the BIOS and report back.

That didn't fix the problem... within 2 minutes of booting up after disabling C6, the computer froze for a few seconds. I checked the Event Viewer, and there it was:

10 instances of the error:

"The device, \Device\Ide\iaStor0, did not respond within the timeout period."
 
I just purchased a C300 and a P67 MB, so I will probably have this same issue :/

I hate worrying about crap like this, I just want all my stuff to work, especially after spending so much for all of it.
 
Fresh OS install?

Enable write caching and turn off write cache buffer in the device manager?

SATA3 or SATA6 Intel ports?
 
I think its luck of the draw. I have the C300 and a P67 motherboard. Mine stuttered and I too get that error in event viewer. I did the fix posted at crucial forums and its been all good since. For some the fix works and for others it doesn't yet we have almost the same hardware go figure...
 
the c400 uses the same exact controller, only with 25nm NAND instead of 34nm NAND, and slightly tweaked firmware. It probably would have fared the same in whatever situation you are in, and would be more likely to have issues due to being new and less widely tested.

do you have TRIM?
The C300 and C400 on a non TRIM capable machine drop to unacceptably bad performance when hammered with random writes. Anandtech m4 review mentioned that and said they will stutter without TRIM.

Also, did you update firmware?

There has to be something in common with the hardware or settings and the drives that aren't functioning correctly.

I've had no problems with my 256GB C300 on an Intel ICH10 or LSI 9240 set-ups.

There has to be something in common.
