High latency for disk activity while writing file intel 80gb G1

[idata]

I was writing a large file to my ssd and my system was basically crippled because the response time for programs went from the usual <=3ms to a peak of 817ms. I got this info from the disk activity tab under performance monitor. I've also noticed that when the drive stutters, it's because the latency increases to ~500ms. Is there a fix for this because buying another ssd with say a SF controller? I'm using a lattitude e6410 with the latest intel ahci drivers installed.

I would strongly recommend not doing that. I haven't tried it myself but users on other forums have said that whilst it works to some extent on OCZ drives it has the opposite effect on Intel drives.

Could you run an AS SSD benchmark and post the results?

Do you have write caching enabled?

Also try a secure erase:

It's sad that Intel chose not to provide TRIM functionality for the G1 drives.

write cache is enabled. i ran the optimizer thing in the ssd toolbox. an error popped up for the read access time

access times went up to 2.2s for the 4k-64thrd part

Boy that sucks. I'd run a secure erase to see if that clears it up. If that fails to improve things something other than the SSD may be at play.

Do you write heavily to the drive all the time?

EDIT: I see you are using MSACHI drivers. (Standard Win 7 default) If a secure erase resolves the problem I'd switch over to the latest Intel RST drivers. (Assuming you have Intel chipsets.)

A secure erase will work.

A G1 should eventually recover but when results are this low, secure erase is the only sensible option.
