With the gaining popularity of SSDs, it was only a matter of time until we started seeing large capacity external SSDs hit the street and the time has come. Whereas less than seven days ago we had never had an external SSD of 512GB capacity, today I have three 512GB and a 1TB external SSDs sitting in front of me as I type. As an added benefit, we can state right off that these external SSDs are probably the most powerful manufactured to date and surprisingly, all can be thrown in your pocket. Today we are going to rip apart and test the new Monster Digital OverDrive 3.0 External SSD seen here. Monster has just released this SSD in several capacities, ranging from 128GB all the way to 1TB. Regardless of capacity, the form factor is the same and this SSD is smaller and thinner than just about any cell phone at 60mm x 126mm x 8mm.
