    A couple of weeks ago, with the announcement of the new MBAs, I decided to test the waters on bay for my mid-2010 15", hi res, 500 gb 7200 rpm i5 machine, figuring I'd sell that and get a 13" MBA instead.

    When I didn't get what I was asking, I decided to take a different approach. I've just swapped out both the HD and the SuperDrive for two OWC 60 gb ssds set up in a striped RAID array. All I've really given up is form factor--and even the MBP 15 is easier to travel with than my old think pad, with its crazy bulky 9 cell battery that still only lasts 3 hours with wifi on and massive power brick--and I've gained quite a bit of flexibility over the Air. If I really want to travel light, there's always the iPad.

    I highly recommend this approach, which might be even more attractive on a 13" MBP than a 15 (though then you're losing resolution).

    How much improvement with striping?

    I'm also looking at going the 15" MBP route with an OWC SSD drive. I really do need a minimum of 240 GB. I was just going to go with the OWC 240, but you got me thinking about a striped pair of 120s.

    Did you compare striped versus non-striped performance of the SSD drive?

    I didn't do any comparisons. Coming from a mechanical HD, I knew I'd see a performance bump either way, and figured striped RAID would be faster than concatenated. Plus, the thing is crazy quiet and cool now...

    As it turns out, I overestimated my space needs and probably could do with 2x40 gb. I budgeted to keep my vm on the ssds, not thinking that would thrash them pretty quickly. I also decided not to reload my iTunes library, but rather to stream over home share.

    Of course, the only problem with striping is that your reliability drops. That is a definite consideration for HDD -- probably a lot less for SDD. Although I noticed that OWC sells a higher end line of SSDs specifically for striping applications.

    Thanks for the post. I have been thinking about breathing new life into my MB 2.2 santa-rosa with a SSD in place of the DVD (that is now bad). I will have to read up more.
