In the beginning there was memory, and it was called flash. It was small, expensive but convenient and the geeks saw that it was good.
What is a thumb drive?
Research done at Microsoft recently found that much of the time the most effective way of moving files around was via the sneakernet. Thumb drives are small pocket sized devices that have no moving parts and can store almost as much information as a CD-R. They use flash memory to hold the data and connect to a computer via a USB port. They generally can get on to all but the most locked-down computers and can be used to remove or transfer computer files. I use a 256MB Sony MicroVault
Why do I need a thumb drive?
Your work computer doesn’t have a CD writer and you want to move a presentation or work on it at home. You could run an FTP server and move the files electronically, but this could be hacked, is hard for a nebbish to set up and relies on your broadband service provider to not fall down at the wrong moment. Its cross platform, I can use mine on my Mac and PCs at work
Cover thy ass
A friend of mine recently ended up in court. The wrangle ended in their favour but it could have been avoided. At the time, redundancies were on the cards and they had developed a business plan in association with another friend regarding the possibility of setting up a new business. The time past and all that was left of the idea was a pipe dream on an spreadsheet that was stored on a network drive that had backed up their email account. Years later when their employer wanted to get rid of them, they used the file as evidence in a legal move to get them out the door. Anything like this, do on a removable drive if you have to use a work computer at all.
