Portable Apps, Carry your Apps with you without having to install them!

"A portable app is a computer program that you can carry around with you on a portable device and use on any Windows computer. When your USB flash drive, portable hard drive, iPod or other portable device is plugged in, you have access to your software and personal data just as you would on your own PC. And when you unplug, none of your personal data is left behind."

Cheap Network Attached Storage with RAID

A Network Attached Storage (NAS) box allows you to store all your files in a central location and connects directly to your network. Both Mac's and PC's can connect to it, and you can even access it from the internet through FTP. And you can store terabytes (1 terabyte = 1000 Gigabytes) of data on it.

RAID (Redundant Array of Inexpensive Disks) adds fault tolerance to your setup. You need 3 hard disks minimum to take advantage of RAID, and becuase of parity data stripped across the drives, even if one drive fails, the array will stay up, you wont loose data and you will still be able to access it. Then you can replace the drive at will.

The first to market with a NAS with RAID is the Buffalo Terastation. Released over a year ago, this is still my recommended option becuase you can get a 1TB terastation for $650 (click here, assuming this deal is still on) This combines 4 250GB hard drives in a RAID array for a total of 1TB of storage. Of course, since the equivalent of one drive is used for parity data you will have about 750GB of usable space. There is also a TeraStation Pro which adds hot swappable SATA drives for about $100 more

Several vendors have realized that cheap NAS RAID boxes are going to be a hit, so Intel has released their own box. They call it the Intel Entry Storage System SS4000-E. This is also $650 but does not include any hard drives, you have to purchase them seperately. Ironically, this box uses Linux and not Windows as you would think from the "Wintels" congolmoration. This system runs faster becuase it has onboard memory and a higher data transmission speed. This would be a better solution for a small business that has multiple users accessing the data at once. It is also upgradable to 2TB. You still would need 4 250GB drives at $100 each for a grand total of over $1000 to be equivalent to the Buffalo solution
