Flash drives are the latest craze in portable storage technology. Technically known as USB Flash Drive (to distinguish from Flash Cards used in cameras or MP3 players, which have different device connections and don’t have as sturdy cases.), they are also know as Thumb drive™ or jump drives™, pocket drives™, pen drives™.

Flash drives are digital storage devices, usually smaller than a pack of gum, which can be used to store and transfer digital photos, business presentations, and music. They are easier and faster than burning a CD or DVD.

They can transfer files between computers (i.e. work and home), faster and easier than ever before. They don’t require external power. They are shock resistant. And most will store data safely for at least 10 year.

• Capacity - 32 Megabytes to 2 Gigabytes
• Speed - Usually quoted in Megabytes or Megabits per second to read and to write (there are 8 Megabits in a Megabyte).
• Size - Range from the size of 3 "C" batteries to a pack of gum or smaller
• Design - Most units have a removable top or a protective case that protects the USB plug. Some are even built into watches, pens or lipstick cases.
• Built in Features - Some have an LED that indicates when data is transferring
• Compatibility - Most require a USB 2.0 port. Some will work with USB 1.1 ports. Almost all will work with Windows 2000, Apple’s Mac OS 9.0, and Linux 2.4.10 or higher without any special drivers. Most work with Windows 98SE and Mac OS 8.6 with a download from the manufacturer.
• Warrantee - Many units have a 1 to 5 year warrantees. Some even come with a lifetime warrantee

First figure out your main uses of the flash drive. Will you be using it to transfer business files between two computers, music files between multiple computers, sharing photos with friends, etc.

Determine your capacity and speed requirements. While business presentations can vary in size, you can estimate typical photos at 1 to 3 MB each and songs at approximately 4 MB each. If you will be transferring often or very large files, consider a faster unit.

Make sure the flash drive is compatible with your operating system and USB ports. If you are sharing files across many different computers (perhaps older ones) consider a unit with Windows 98SE and USB1.1 compatibility.

Finally, look at warrantees. Although most units are built for abuse, a good warrantee can protect you against product defects.
