I'm glad I picked up the x25-m 160GB for $419.99 when I did!

For what OWC is charging for the 200 GB drive I'd sooner get the Crucial RealSSD c300 256 GB drive for less money off newegg.
I wonder how many of the 200 GB model they've sold. The 160 GB G2 intel drive can be had for under $500 online. I just don't see people forking over another $300 for 40 gb of space from an unproven SSD vendor.
If Apple would implement TRIM in OS X already we wouldn't be having this conversation. I'm not sure what's taking them so long. They've had SSD options on notebooks for a while now.
In Windows you can use HDDerase. I'm not sure of a way to issue the secure erase command in OS X but you can buy a tool that does something similar from this guy: http://macperformanceguide.com/Storage-SSD-Reconditioning.html
I also think its incorrect to say that OWC is unproven - relatively speaking. The problems are the controllers not the end vendors. Most of them are rebranding drives that are made by one or two manufacturers. Crucials realSSD series is just as unproven as OWC's MEs. It uses a brand new Marvell controller. Crucials other SSDs use the Indilinx which we all know about the Pros and Cons. Both Marvell and Sandforce are proven companies and I would bet on either of them to have a quality product.
USB 2 maxes at around 55 mb/sec, so you'd really be throttling an SSD drive in there.
A mini update from Anandtech about about the latest Crucial drive. Unsurprisingly, it's got some issues.

Regarding the OWC boot drive and intel as the external, I don't understand why you'd want to do that. You'd want to relegate an SSD to a USB enclosure? USB 2 maxes at around 55 mb/sec, so you'd really be throttling an SSD drive in there.
And with respect to degraded writes, just look at the link i posted. The crucial drive shows to have slowed to well below HDD write speeds even after TRIMing.
Marvell is a proven company. They've been around since 1995, and they make a variety of integrated chips and controllers. Sandforce was founded in 2006, and their first products (SSD controllers) were released in 2009. There's not really that much information about them out there, as evidenced by the fact that the only Wikipedia article about them is in Japanese.

More like 30-35 MB/sec.
I keep going back and forth on this because I keep hearing different things.
So... Dual SSD drives. Who could do an optical drive removal to put in my second SSD? I look at OWC video for replacing the first HDD and am confident I could do that. I am not confident in the second one.
So... where does this leave me?
I think you'd have to find out if it'd even be worth it. I think you might be limited by the available bandwidth of the SATA II interface if you wanted to raid two SSDs in a current gen macbook pro.
I'm not running the new C300 drives. Any commercial program you can use to do a secure erase
For a bit of perspective, I've been running a C300 in my 15" unibody for just over two weeks and it's fantastic. Everything feels extremely fast if not instant and due to the lower temperature (hard disks get *hot*) the fans only ever come on when using Bootcamp to play games. I use the MBP for long hours every weekday for general internet use and app development, occasional gaming and also for running three windoze virtual machines (Sun VirtualBox) for my work.
