Summary: I had researched external hard drives and some of them dropped old data when new data was entered. This one is so easy to install, use and you could line them up like books because of the way they can stand on edge (also can lay flat).
Summary: First the bad: The automatic backup function is seriously flawed. The default setting is to save files by "Category". After the first backup, the software would no longer save new files. For 3 weeks, the software would tell me that all my files were backed up, 100%, all good.
Summary: I had bought one of these from Wal mart. When it fell in the floor and the USB port on it broke loose I had to find a replacement to put my original drive in due to the encryption the adapter card puts on it. My wife insisted I get this and I'm glad she did.
