Hi,

i am one of those Macbook pro users who hasn't been able to bring themselves to buy a Macbook Pro (or other) with an SSD. I got a lot out of the OWC SSD review, but am not sure I got everything I need regarding garbage collection and long term use degradation when using such a drive on a Macbook pro

The main question I have is:

Will I get garbage collection (not necessarily 'Trim', but I assume there are other techniques) with any of the available SSD drives when used with a Macbook pro (I am willing to pay up for an enterprise class drive if that is what it takes)?

thanks

OWC drives are specifically designed for Mac OS X and protect against degradation of the SSD.

You can read more about it there. Scroll to the bottom of the page to read reviews.

SL does not support TRIM this is true.
Just get the Mercury from OWC as it is specifically designed for Macs. Buying a different SSD with TRIM is pointless (like Vertex 2, Phoenix Pro, etc) since Snow Leopard does not support it.

Snow Leopard does not support TRIM so the answer is no. Garbage collection is not supported. Chances are (we don't know for sure) that the next major upgrade of OS X (Lion) will have support for TRIM built in.

Mac SSD performance and TRIM in OSX | bit-tech.net

It may well be Snow Leopard does not require TRIM. Have a look through th above link particularly page 7 Analysis "Does Mac OS X need TRIM?". Use an OWC SSD and very impressed with its performance but if anyone goes this way a clean install is essential as cloning makes the drive as slow as a normal hard drive.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Interesting article harry. Thanks for linking to it. It does raise more questions though doesn't it? Some other food for thought.... the new Air machines use Flash storage. How is that affected? Or is it the same as an SSD?

Great thread, I have some of the same concerns over long-term viability. I notice that there's been a lot of articles out there about tuning different applications to prevent SSD issues. In particular, moving caches for applications like a web browser over to a RAM disk in order to avoid constant writes and re-writes. There seems to be some sound reasoning associated with these recommendations.

Maybe I'm being a nervous nelly, but I'm having a hard time parting with $400+ even though I REALLY want a 256GB SSD based on some of these comments.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Q: What is different about OWC's Solid-State Drives that separates them from the rest of the market to earn the "Made for Mac" title?

The controller inside is specifically designed for Mac OS X. Plus it can potentially read/write faster.

I guess I was looking for a more technical answer. OWC uses a SandForce SF-1200 controller. This very same controller is also used in Corsairs and OCZ SSDs.
