I would like to see if there is a way of getting TRIM support on SSD drives gotten from other manufacturers.

As far as I know, Apple does not produce SSD drives so if I get a similar drive not from them it should work? Or maybe they have custom firmware?

Enabling TRIM on third party SSDs

You can enable TRIM on third party SSDs by using a tool called Trim Enabler which "works by patching a kernel extension, and also includes some SMART data to check the health of the SSD drive". [1]

I don't know if buying similar drive will get you TRIM to be auto-enabled in Lion. User @kukoo reports that he has bought an OEM-SSD which auto-enabled TRIM in Lion after installation. [2]

According to user @bmike, Apple usually uses custom firmware . [3]

Is enabling TRIM necessary?

User @cksum has covered this as a part of his answer to a post "Optimize MacBook Pro for internal SSD+HDD drives".

I replaced the optical disk in my macbook pro with a Sandisk ssd, and built a hackintosh with a Crucial ssd -- both are trim enabled with this method. –  Roy Jul 18 '12 at 21:48

OWC's SSDs work great http://eshop.macsales.com/shop/SSD/OWC/ and have Mac TRIM support.
