It's quite clear that the burden is now on Apple's side - they have to update the drivers.
The only other option for the time being is to use Disk Utility, and do do a full/secure erase option that writes the partition with 1s and restore the partition from backup such as Time Machine - doesn't take too long for me.
The other option is not to care about write performance so much and enjoy other benefits of SSD - read speed, silence, no moving parts etc.
Exactly, the disk utility's disk erase does not tell the disk that the data on the disk can be overwritten without the usual read-modify-flash-write procedure and thus, the write speed should not increase just by overwriting the disk with 0's (this is what disk utility does) and rebuilding the data from a second disk.
I agree that Apple should add TRIM support for Mac OS X and indeed there seems to be at least one person at Apple who's considering:
What's stopping Intel from providing support for their SSDs in OS X, via a utility?
Surely it can't be seriously argued that Apple will prevent Intel from providing TRIM functionality via a utility because it sells Samsung SSDs in its largely Intel computers...?
Certainly, I agree that it's ideal to have OS-level support. But, I think the minimum acceptable level of support is for Intel to provide even a basic command-line utility that a user can run the TRIM command on HFS+ volumes with. In fact, I wouldn't be opposed to a bootable USB keychain device image containing such a utility. Anything is preferable to the current situation with absurd kludge like periodically writing an entire drive with 1s.
