120 GB G2 - What Does This Mean (End to End Error Detection Count Change)?

[RhoXS]

Two weeks ago I replaced an Intel 80 GB G2 with a new Intel 120 Gb G2. At that time I ran the Intel SSD Toolbox and recorded the results of SMART Attributes. I ran it again today and noticed a change.

End to End Error Detection Count
Raw---Normalized---Threshold---Date
0------100------------99-----------3/16/11
0------100------------90-----------4/2/11

What is the significance of "Threshold" decreasing from 99 to 90?

I did upgrade the firmware a few days ago to 2CV102M3 and yesterday I did briefly switch to AHCI until switching back to IDE tonight because I noticed a 5 second increase in boot time (beginning when "starting Windows" appears) with AHCI.

I just checked mine, and I'm still 0-100-99 (started using drive on 03/24).

Why did you update the firmware -- was there something significant that this addressed? I'm still at 2CV102HD.

You're running the drive all of the time as IDE now? I thought SSDs needed to be set up as ACHI. (?)

I ran my first SSD (Intel 80 GB G2) as IDE from Nov, 2009 until last month when I replaced it with the 120 GB G2. There was no conscious decision to do this. It just happened by default because I never was triggered by anything that indicated faster performance with ACHI. I only experimented with ACHI briefly because I read some articles that led me to believe there might be some benefits. When I noticed an increase the time W7 takes to start and then measured a 5 second difference (18 seconds to 23 seconds), I decided IDE was not broken, it was a mistake fixing it, and reverted back to it. I know of nothing that indicates a problem using IDE with an SSD except for the loss of the features ACHI supports.

I generally maintain all my significant hardware with the latest firmware. I certainly recognize there is a school of thought that there is risk doing this if there is nothing driving the change. However, it makes me feel better having the most up to date firmware as long as I see nothing negative about it in the various forums.

The 'threshold' is the level at which the drive triggers a BIOS alert (pop up warning saying 'replace drive soon')

The old firmware set a threshold if 99% drive health for an alert. The new one sets 90% health as the level for a 'replace drive soon' alert.

Your drive is still at 100% health for 'end-to-end' errors, so there is no concern.

Thanks - I appreciate the explanation.

Seconded... thanks much!
