SSD upgrade and Lion

In the case of OCZ, it will make your life monstrously less insufferable if you ensure the drive has the latest firmware revision before installing it in your Mac, as OCZ does not support OS X (they provide a mixed bag of solutions that require a decent level of computer expertise and Linux distributions which are rickety at best). They make great hardware but have deplorable Apple support even after all these years.

You can view the latest firmware for your drive here. The utility requires either Windows or Linux and a working networking connection. It is also recommended you back up your data as the update could wipe it, so naturally it is best to do on a fresh drive. v2.1.5 has been out for a while so it is quite likely you won't need to update. Support forums are available in case you do.

If Lion shipped with the unit, you are in luck. The computer is capable of using both the Lion Recovery Disk Assistant or the Online Lion Recovery process (hold COMMAND+R after you hear the chime. Both will download Lion and install it for you. All new machines have their unique identifiers registered with Apple, so barring a complete logic board swap, they will always have access to Lion without the need to pay for the OS. In fact, your copy of Lion operates entirely outside of the Mac App Store.

Note: Be wary of partitioning tools (like SuperDuper, etc.) as Lion has a Recovery HD (weighing in at 650 MB) installed alongside the OS. This is there to either help with the reinstallation or diagnose and repair your system. It does not house the entire operating system, but rather things like Terminal and Disk Utility. Currently, partitioning tools do not clone this partition and the one's that are including this feature, are still in the experimental stages. Be careful.

Personally, I would verify the drive has the latest firmware revision and then install it in your Mac. Use either the Lion USB stick you created via the Recovery Disk Assistant or the built in Online Recovery and install Lion. That's it.

You can't. Apple has implemented a Compatibility Support Module (CSM) into the Mac firmware that emulates the PC BIOS specification. Since the Mac firmware is not 100% UEFI compliant, that CSM is the only way Windows can boot on a Mac.

Unfortunately, the ACPI tables in that CSM are just the bare minimum necessary to allow Windows to boot and nothing more. You lose several features when using it:

• No graphics switching (always uses the discrete card).
• No AHCI support (SATA devices are in IDE compatibility mode)
  • No support for TRIM
  • No support for Native Command Queuing (NCQ).
• No support for advanced power management features (only basic S1, S3, and S4 states are supported).

Basically Windows sees your SSD as just a really fast IDE hard drive. This will not affect the SSD in terms of lifespan. It may, however, make the SSD a little slower over time than it would otherwise be when running Windows.

NOTE: Some people have reported that they have been able to install Windows 7 in UEFI mode on a Mac, which would enable all those missing features. However, it cannot be done on your model. I've tried. With sufficient hacking you can get it up and running, but it's plagued with audio and video issues.
