Most geeks can understand the allure of a SSD drive with much faster data access, read and write speeds. What most geeks can’t get behind is the huge price premium you pay for the SSD when compared to a traditional hard drive and the amount of storage space you give up.

Today a typical hard drives in a computer are at least 80GB, even in tiny ultra portable systems. If you opt for a SSD you typically get 32MB, though some larger SSD drives are available like the 832 GB BiTMICRO SSD from CES 2008.

Imation has being showing around at CES its updated line of secure, rugged Pivot Flash Drives. Two models make up this family - the Pivot and Pivot Plus - and they range in price around $70 to $250.
