    Pretty sure you won't have to buy an Apple provided SSD to have TRIM. It would be powerfully stupid for Apple to make that move. I just don't see it happening.





    To the 2nd part, it's appearing so far that non-Apple BTO SSDs that do support TRIM in other OSs aren't showing up with TRIM supported in these OS X builds. To prevent getting post deleted again I won't use the L-word.

    Im sure if you just kept on the subject at hand, that wouldn't happen.

    Let's see - I replied to a poster who mentioned that he was running that same build with a non-Apple SSD and TRIM didn't work by adding more information.



    Bucking for moderator or one of those editor slots they've opened up? How did you add ANYTHING on topic?



    Pot. . . meet kettle. k thx

    I wonder if TRIM support will be extended to the Apple supplied BTO option in my recently purchased iMac.

    Not all SSDs support TRIM, but most released within the past 12-18 months do.



    Still, that is correct even for drives that do support it.

    I wonder if you Boot Camp Windows 7 if Windows has TRIM support.

    Elegant in that you'll have to buy a brand new MBP to use it?

    Windows 7 has it by default. Most SSDs have had TRIM support for at least two years. Seems like my $1200 drive doesn't...

    First of all, this isn't news any more, as we've known this for some time.



    Secondly, until 10.7 comes out this summer, trim only supports the Toshiba SSD's Apple installs, though it may work with other drives using the same model Toshiba controller.



    Apple has had partial trim support for some time, but it was only for third party testing purposes. Trim is such a basic OS level system that it must work perfectly, or not at all. Apple is conservative about such things, and using it only with drives they support for now, makes sense.



    But, if you buy a drive with a Sandforce, or similar controller, trim support is much less of an issue.

    You shouldn't have to, as this is an OS attribute. When 10.7 comes out, most machines should be able to take advantage of it.

    Many SSDs didn't come with it but it was added with firmware updates. Hoping if Apple's older SSDs are capable with firmware, that it'll get done.

    I suppose booting Windows in Boot Camp would give Windows direct hardware control and that TRIM would work on a recent-vintage installed SSD, whether or not from Toshiba. Using a Windows guest OS in a virtual machine would not enable TRIM, however, as hardware calls from the guest are mediated through the virtualization hypervisor, and the OSX host, at least according to what folks are saying here re the current downloadable build of 10.6.6, does not support TRIM.



    All of this is interesting for someone considering buying a BTO MBP with base-config HDD, swapping out the hard drive and substituting an SSD with higher performance and at lower cost than Apple's Toshiba SSD. I wouldn't do it yet.



    And as for Toshiba, Apple seems married to their SSDs.

    For Apple picked SSD's, or for any SSD?

    Err, how much more elegant can you get than a command that runs when idle by default?

    They used Samsung SSD's for two years first. Toshiba has a very aggressive controller which gives much better performance, but may lead to shorter drive life.

    I've been using an Intel X25 G2 in mine for nearly a year now, and even without trim, there is minimal slowdown with normal usage. Only if you're OCD and perform benchmarks every day you would notice smaller numbers under write speeds over time.



    But I do hope they support third party drives, Apple's SSDs are way overpriced and often much slower.

    Ah, very good question sir!



    There is a teeny problem with trim as it's now implemented. If you RAID two or more SSD's together, TRIM DOESN'T WORK!



    How about that? Turns out that it can't understand two or more SSD's together. If Apple could solve that problem, their trim support would be more "elegant".

    Apple's current SSD's are not overpriced, and they're pretty fast.
