    My latest tinkering project is done. :)

    After upgrading my MBA from 64GB to 128GB (out of warranty anyway), I thought that instead of selling the 64GB for ridiculously little money it would make more sense to buy another 64GB blade and two SATA adapters for them.

    So I dug around a bit on eBay and got a 64GB blade for ~€30 plus two adapters for ~€30, both including shipping.

    Just threw them into my hack, created a RAID0 from them using Disk Utility and applied some terminal commands. (the latter because a hack won't just boot from a softRAID)
    This RAID is way faster than the Intel 320 80GB SSD I used before (see attachments).

    Nice side effect: Since they're original MBA SSDs, they have native TRIM support.

    This will work in a Mac Pro, too, of course.

    Depending on the Solid State Disk, they may or may not support the TRIM command while in RAID-0.
