MacBook Pro :: In Absence Of OSX TRIM Support, How Can I Restore SSD Performance On A Mac?

Whenever the MBP refresh happens I intend to upgrade the stock HDD to a 7200rpm 500GB HDD or, less likely, to an SSD. An SSD had been my first option until I learned about SSD performance degradation and the lack of TRIM support in OSX. I was ready to stomach the massive SSD price premium, but the lack of TRIM would most likely rule it out completely for me. And I recall reading something about the MBP hardware connection (perhaps the the SATA connector) having a slight bottleneck compared to SSD-equipped Windows machines; so some of the top of the line SSDs won't be able to max out their transfer rates on OSX. (This is the best, not so informative, link I can find now referring to that impaired performance: http://macperformanceguide.com/Revie...tml#Single_MBP) With these performance issues, I've become perplexed why SSDs are popular amongst some Apple users
