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)?

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.
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-10...
[edit] Well, if you look at the numbers, one column actually got worse. Wow.
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)?
