    Hi all, im looking at buying an external hard drive form OWC >

    http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/PerformanceRAID#

    and am confused as to their description of the drive. Is it writing all of my data twice, so I have a back up for my back up, or is it splitting the information across two drives? Surely having bits of a file across two drives would be useless if one of them failed?

    Also, does anyone have any experience with this company/drive? or other recommendations for an external drive? It doesn't need to be too portable, just robust, reliable and if it were able to save all of my files to a second back-up, that would be ideal.

    thankyou, Mike

    I'm generally against the idea of striped (0) raids. It's twice the chance of failure, and the improvements you gain in speed aren't anything worth writing home about.

    I have the single bay version of that enclousre, as well as a Guardian Maximus, and I can say they're both quality products. They're a bit on the pricey side, but you get what you pay for.
