Buyers remorse? (Some SSD Raid questions, Random Access time, Thunderbolt...)

    I've been testing my new setup rMBP with Logic Pro and multi-track drum editing, so I did some testing.

    Editing on the usb2.0 or fw800 was just awful, even play/stop response is vomit-inducing slow.

    Internal drive isn't all that big, but I copied the project over and tried it there. Transient analysis, overall response much better. 450mb/s.

    I then wondered if I would benefit from a faster drive... Meaning cMBP dual SSD raid0 setup for even more snapiness.

    So I created an 8GB RAMDrive and tested it real-life. The SSD jump from FW800/USB2.0 or even internal Raid0 HDD (tested on my cMBP) means instead of waiting 10secs for enabling/disabling quantization track to 1sec.

    Using RAMDrive instead of SSD means waiting 0.5sec, and project doesn't load any faster. (its already instant with single SSD)

    That leads me to believe I actually benefit more from random access time than actual bandwidth in practice when working with my projects.

    Also actual bandwidth used isn't more than 2-6 MB/s.

    As far as I know random access times go haywire when doing an SSD RAID0...

    In this particular case, would I see worse performance going RAID0? (>> no buyers remorse if true)

    Also, I'm waiting patiently for this:
    Can I hope to get the same Random Access Times as from internal sata?

    I didn't know all this when I ordered, otherwise I'm pretty happy with my retina.


    btw, if someone wants I can upload a simple RamDrive script I whipped together.

    Anyone who actually knows anything about SSD or RAID would have told you that before you did it ;)

    So no buyers remorse for me I guess. :)
