You can not Secure Erase the the drive while Windows is running on it. needs to be as a secondary drive.
I do alot of testing, experimenting, and messing around.
Therfore, I do many, many System Restores from a Acronis Back Up.
Even with so may restores, I have only done a Secure Erase on my Intel Drive 1 time.
its has so many re-images I lost count a long time ago, as well as a couple Clean Windows installations. Its still running just as good today as day 1.
With my OCZ drive, after a period of time performance starts to degrade. Especially if it gets re-imaged too much.
It ends up needing a Sanitary Erase to regain its performance, especially if I wanted to re-install Windows on it.
My Intel drive however seems to maintain its performance regardelss how times it gets re-imaged. It just hangs right in there. Sure, it might drop in performance slightly after a few, but if I leave it alone its right back up to speed in a day on its own.
Newer OCZ drives may very well be different, but thats one thing I love about the Intel.
Anyway, the point is & many may disagree but ...
Secure Erase should only be done if absolutely needed.
For the purpose of re-Imaging and daily use, it doesnt hurt it performance-wise.
I would even say, re-installing Windows all that you really need to do with Intel, format it and continue on.
