Dave, I read on the Intel site that the Intel SSDs do not do idle time garbage collection. ie. idle at logon screen. Do you have any experience to dispute this? I know OCZ does do that as well as most other brands.

That's correct, Intel runs Trim differently than most others.

It's recommended to run the ToolBox once a week. It takes about a second and it's done.

Intel SSDs do not have idle time garbage collection (ITGC) or background garbage collection.
The downside to idle/background garbage collection is write amplification as it may perform unnecessary writes.

While Intel SSDs do not idle/background garbage collection, they have are very resilent to dirty pages.

If TRIM is working, you do not want/need idle/background garbage collection. For Intel G2 drives not in an array, the SSD Toolbox Optimization is a manual garbage collection (and can be scheduled). The scenario where you want/need idle/background garbage collection is SSD in RAID.

Dave, on extreme systems they have been testing SSDs. The Intel finally got to a 99% wear out, but it took 11.6TB of writes to do it. I don't think I could do that if I was trying. There is some really interesting info on how SSDs and trim actually work.

I guess that depends. The forum where they have been testing the Intel320 and X25 TRIM is kicking in as they run them.

They can watch it on a graph dip the write speed for about 5 seconds on some but about 1.5 seconds on the Intel320. Of course they are pushing terra bytes of info thru them.
So if it gets bad enough it will TRIM out or is doing it after the SSD is full.
They are filling them up so once full the TRIM may kick in.

This is the quickest at recovery by the way. OCZ is taking 5-10 seconds.

My 320 has the TRIM hang you speak of as well, but it only lasts 1.5-2 seconds. After this, the speed drops to about 39MB/s over the period of 30 seconds. During the next 30 seconds it slowly recovers to 42-43.
Amazing testing to follow.

Intel 320 is 24TB of write and down to 88% wear showing.

And people worry about putting page file on the SSD. Without a test program like they have, you couldn't write that much in 20 years. At least I couldn't.

But it is quite amazing if you think about it. 24TB of writes to a 40GB drive. I think trim must work quite well.

That reminds me that the university of Karlsruhe here in Germany is just now testing a new network based on laser. The transfer rate is 36TB/sec. That could wear out our good old SSDs in a jiffy.
