How to install Linux on a USB flash drive
There are five things you'll want to consider when buying the perfect flash drive for Linux. If we order them with the most important first, it looks like this:
- Reliability. This is easily the most important thing to care about, because it doesn't matter how cheap, fast and spacious a flash drive is when it dies after 20 minutes. If losing your data is simply not an option (and, let's face it, that's almost certainly the case), go for a brand name you trust - we chose Corsair, because it's a company with a huge amount of experience making quality flash drives, and its Flash Voyager range is designed to be water- and shock-proof.
- Cost. This is always going to be a consideration, but fortunately flash prices have dropped dramatically in recent years - whereas 256MB drives used to be £60 or £70, you can now get 32GB drives for the same price. That's over 100 times the capacity for the same price!
- Capacity. 1GB is the absolute minimum needed to get started, but it really depends on how much data you want to store - and also how much extra software you want to install. If cost is an issue, the best value drive sizes right now are 4GB or 8GB.
- Speed. The simple rule here is "pay more, get more". Companies such as OCZ and Corsair specialise in high-performance devices - Corsair even makes a special range of flash drives (known as 'GT') that are made from extra-fast components. Remember, your entire computer will be running from this tiny device, so only go for a slow drive if you're a very, very patient person.
- Size. Arguably the least important consideration is the actual physical size of the flash drive. This isn't usually a problem because all flash drives are necessarily small, and it's only if you're after a particularly tiny one that you even need to consider this. SanDisk's Cruzer Micro and Corsair's Flash Voyager Mini both come in 4GB and 8GB capacities, despite being less than half the size of conventional drives.
Make your choiceThere are two distinct ways of running Linux from a flash drive, but we'll only be covering one of them here - and for good reason, as you'll see.
