Have a read of my thread about the issues I had with getting AHCI mode to work from my previous build of Windows, I used True Image also. There was nothing wrong with using TI the problem was, I think, with my build of the OS. The process of using TI was as painless as it has been on any mechanical drive.
Have a read of the official OCZ forums they have a lot of information on what you should and should not do with the drive. Basically I have turned off Defender, Indexer, Search, HD power off options and I did a quick format using the Windows install CD. I read on the OCZ forums not to use a full format on the SSD drive. You do not need to defrag a SSD drive.
I was going to buy the 120GB drive but after chatting with the sales person, and rethinking what I wanted to do with it, I decided for the 60GB. That will do me until the newer drives next year. That has allowed me to install the OS with all my applications and a steam install with the one game I'm playing at the moment. As yet I have 28GB free, but maybe something else might go on when I remember what is missing..!!
Performance wise it is nice but as I do not switch my PC off, I use sleep, I'm not sure if the boot process is quicker. It is useful for my apps like Photoshop Elements to open much faster but, for me, it is the silence that I really enjoy.
Use ATTO to measure the speed and try and not run it too often as that can degrade the drive.
