What about the promised benchmarks?
Could try Filevault 2 speed too?
That would be great. Since OWC drives use the SandForce controller, I expect performance will be similar to the Toshiba drive, unless Toshiba did some significant customization of the firmware.

Could you try with?
will sure do - once I resolved that issue ...

well ... looks like no TRIM after all

interesting!
I wonder if OWC has done something with the firmware to disable TRIM. I don't agree with their analysis that it is unnecessary. TRIM and GC complement, not replace each other. And Apple has certainly enabled TRIM for the Toshiba drive, which also uses a SandForce controller.
a reboot - fair enough - resolved it, write performance didn't change. I will post some filevault results later today - back to work in the meantime
yes ... MBA 13.3" 2012 i5 8GB RAM OWC 240GB SSD is very similar to stock Toshiba SSD
There are 256GB of NAND on both drives. Samsung overprovisions about 6GB for the drive, leaving 250GB of space. OWC overprovisions about 16GB, leaving 240GB of usable space.

Isn't that behaviour supposed to come from Windows?
For everybody who wants to buy an Air and use Filevault 2 but doesn't know if they should go for the 256GB Apple SSD or a cheaper version and upgrade to the 240GB OWC SSD I've included the following benchmark of my 13" MBA with the i5, 8GB of RAM and the Apple 256GB SSD (SM256E). Am hoping somebody else can do the same for the 240GB OWC SSD for comparison.
None. Garbage collection is what they use and it is as good as TRIM. It is only used to clear out mem cells marked as "not in use any more". It only makes a difference if you filled the drive than cleared it out. The performance when it is filled isn't that good (write mostly but read a little bit) just like with an ordinary hdd. Clearing out cells that are unused helps in this regard but this requires cells to be marked as "not in use any more", in other words, it requires you to do some cleaning up. This is a problem for any ssd. A Samsung will have this problem as much as a Sandforce drive will.
The use of uncompressible data like jpg, mp3, encrypted files and so on will affect read & write tremendously in case of a Sandforce controller. It's just how the Sandforce controllers work.

The Apple Store employees are not the most knowledgeable people on their computers.
The SSD and according to iFixit the battery are removable. The SSD has a proprietary Apple connector, but it can be removable. The RAM however is soldered to the motherboard.
The SSD and batter are not "glued" in.
Quite sad prices for the 2011 models being the most expensive....even 2010 is higher than 2012....I think OWC prices their things unfairly as well but its also because they can...being the only after market SSD providers for Macbook Air's....
Those of you that are going from 128GB to 256 for the 2010-2011 models I would highly recommend buying one off of eBay instead of OWC's 240GB....its a much better choice unless you going with the 6G series....
