Interesting that they are now offering a SSD drive......does this mean they have now added the SSD TRIM command (or planning to add it in Lion)?

they've always offered SSD

  Indeed, they've done so for some time now. I hoped it would be the default in the new MBP's... :-(

There is already an SSD option for current Macbooks. No TRIM.

newer SSDs (Vertex 3 Pro) actually perform worse after a TRIM

  _worse_? I'd expect worst-case no-change, if it would hurt, the vendor would make TRIM a NOP. However, I'm always open for a source. (AnandTech for instance writes, TRIM just doesn't help, at http://www.anandtech.com/show/4159/ocz-vertex-3-pro-preview-the-first-sf2500-ssd/6 http://www.anandtech.com/show/4159/ocz-vertex-3-pro-preview-...) [edit] Well, if you look at the numbers, one column actually got worse. Wow.

Not sure why you were voted down - I really want to see Apple support TRIM, too. Does anyone know whether there's a next-gen interface standard that's being worked on that might supersede SATA, with more elegant support for flash memory (beyond SATA's hacky NCQ+TRIM)?

  High-end SSDs may migrate to PCIe with NVMHCI.

  Built in garbage collection in newer SSD's makes it unnecessary.

So I (blindly) thought that an Apple-integrated SSD might somehow be better than an aftermarket add in I drop in, RE TRIM. Is this not the case? IANAHDS (I am not a hard drive specialist)

According to a benchmark, OS X doesn't really require TRIM to keep the performance up. Please see this link: http://www.bit-tech.net/hardware/apple/2010/07/01/mac-ssd-performance-trim-in-osx/7 http://www.bit-tech.net/hardware/apple/2010/07/01/mac-ssd-pe... I have been using two Intel X25-M SSDs as RAID 0 in a Macbook Pro almost a year now and I've yet to see any loss in performance. Apple has been offering SSDs as BTO for quite some time now. If you can use a screwdriver I suggest you buy a Sandforce-based SSD and install it yourself as those are immensely faster than the Apple-provided ones.

  That article is misleading for a number of reasons, foremost that they performed a full format before getting started, effectively trashing the SSD's performance. See here: http://news.ycombinator.com/item?id=1486847 http://news.ycombinator.com/item?id=1486847 However, TRIM support is mostly a moot point if you go with the Apple offered SSD upgrade, since the Toshiba drives they ship features very aggressive background GC (making TRIM rather redundant). There is still a question mark as to how severly this constant background GC will affect the durability of the drives though:http://www.anandtech.com/show/4010/kingston-ssdnow-v-plus-100-review http://www.anandtech.com/show/4010/kingston-ssdnow-v-plus-10...
