RAID technology on portable hard drives might sound new to some IT professionals. Of course, for the IT professionals, you should have been very familiar how RAID is being used on the server-side data storage such as how RAID 1 could give you mirrored copy of your data and RAID 0+1 increases the performance of data read and write as well as mirroring your data etc.
Norazza is the company that thinks RAID 1 or mirroring technology is important too even on portable hard drive. Imagine, you have a portable hard drive that you always bring along and it stores all your precious data. But, one day the hard drive fails to read its data, that would the biggest disaster for you. Norazza’s PocketRAID is a little external portable hard drive that is equipped with RAID 1 technology. The PocketRAID consists of two 1.8 inch laptop hard drives, data is being written to is automatically duplicated onto two separate hard drives. Similar to RAID 1 used on server-side storage that if one drive fails, you still have everything backed up on the other drive.
The PocketRAID is 5 inches long and 1.5 inches high, and weighs under 2 pounds. It supports drives up to 160GB in size, so you’ll get 160GB of available mirrored storage. It’s equipped with USB 2.0 and eSATA interfaces, it’s both fast and versatile. The smallest version 60GB is asking for a price of $439, and the largest 160gb is priced at $929. Sounds pretty expensive? Bear in mind, your data are more expensive!
