Solid state drives have been the single largest performance boost PCs have seen in years. While SSDs are not a new technology, the more recent price drops have brought them into the mainstream and out of the prohibitively-expensive category.The downside is that for certain users, the average 120GB or even 240GB SSD just doesn’t have enough storage. For those who upgrade their laptop on a budget and go with a smaller <100GB model, it is even more of an issue. Newer laptops have small “SSD-on-a-stick” mSATA drives that plug into the motherboard and are the size of a stick of RAM, allowing for a larger traditional hard drive to remain.For everyone else that needs more storage on their SSD-equipped laptop, or those that just need to keep their files backed up, a portable, external hard drive makes a lot of sense.Portable drives like this Buffalo MiniStation Stealth 1TB model use a 2.5-inch laptop hard drive in a small enclosure. The low-power, compact drive allows the unit to be powered by a USB cable alone and it is small enough to easily slip into a bag.Traditional hard drives still continue to advance, albeit much more slowly than solid state storage, and we now have 1 Terabyte drives available in the 2.5-inch form factor; and at reasonable prices to boot.In addition to the portable USB 2.0 drive, Buffalo also includes software to help automate and manage your data backups and the security of that data. This drive generally sells for $99.99 or higher at most retailers, but for a limited time you can get it for just $79.99 with free shipping.Click here to get the deal from Dell.com with $20 instant savings applied automatically.
