my-Ditto exists in the crowded NAS product space, where more familiar brands like Seagate, Netgear, Iomega and Buffalo already play. For more money, you get more features, like on–disk encryption, WiFi connectivity and FTP services but, frankly, most folks don’t need those additional bells and whistles in a NAS for your house. I checked Froogle and, at $200 to $375 retail depending on capacity, the cost is significantly less than many other offerings and the feature set is great. Dane-Elec’s my-Ditto is a stylish, affordable and solid foundation for your domestic storage and streaming needs.

RAID or Redundant Array of Inexpensive Disks, is a method for increasing performance and/or decreasing the likelihood of data loss. RAID 0 is designed to increase the performance over a single disk by using two or more drives in parallel. RAID 1 uses “mirroring,” writing the same data to both disks simultaneously so, if one fails, the other is still accessible. RAID 0 has no redundancy so, a failure of either disk means all of the data — on both disks — is destroyed. RAID 1 protects your data as long as only one disk fails which, to me, is better than no insurance at all.
SPAN mode spans or concatenates the two drives, logically stitching the two disks together so they appear as one big volume. JBOD, or Just a Bunch Of Disks, is a mode where they mount as two distinct disks. The disks are completely independent, hence the name. Again, both SPAN and JBOD modes offer no protection whatsoever if either disk fails so, caveat emptor.
