Firmware upgrade after windows installation

[idata]

Sorry if it is a question already answered, but I cannot find it and having read all these posts on firmware upgrade problems, I just want to be sure.

I just received my new x25-m g2 80 GB and I don't want to upgrade firmware until Intel comes out with a new one, hopefully without problems. My question is: if I install Windows 7 now, with firmware 1.3, and I upgrade later to 1.4 or whatever will be, will Windows TRIM be aware of old data blocks erased (and in need to be TRIMMED), or it will only be aware of data blocks erased after firmware update?

It is a pain for me to watch my Intel ssd and not to install W7 instantly But if I have to reinstall it later, it is better not to have a useless write/reinstall on ssd cells. Thanks for answers.

Im running Vista and a Single (due to RMA) SSD and another Raid0. Bios is set to Raid. Firmware update does not work with adapter set to RAID, but the Toolkit works.

Hope that helps.

Blowd: That's what I thought but Fernando is suggesting the toolkit optimizer still won't work if chipset is set to RAID mode, even though the SSD is not part of a RAID array itself.

Checking again I'm not sure this is right as the toolkit optimizer allows me to select the SSD and allows me to run it with a status of Passed. I would expect some sort of error message if this were not the case. Reading the white paper I can see it suggests the Optimizer does the same as TRIM for those of use that are not using ACHI.
