I have found the following devices. Is there anything better for a comparable price? Drobo is a little spendy for me right now.
Western Digital My Book Mirror Edition 2TB USB 2.0 Black External Hard Drive WDH2U20000N
LaCie 2big Quadra 2TB USB 2.0 / IEEE 1394a / 1394b / eSATA External Hard Drive 301352U
I'm about to start a small business of onsite computer repair. One of my greatest concerns is carrying a portable HDD for performing backups that may possibly fail before the data can be put back on the customers computer. I've gotten liability insurance planned but I'd rather not have to deal with that situation.
Can anyone provide good hardware and/or software solution? I was looking for something external with dual HDD's for doing a mirror across both.
