ZDNET's cardinal takeaways

• Running Linux from a USB thrust is possible.
• You tin footwear conscionable astir immoderate distribution you want from USB.
• There are immoderate things you should see earlier going this route.

I've utilized Linux successful conscionable astir each measurement imaginable and for astir each usage case. I emotion really elastic nan open-source operating strategy is because it removes astir limitations recovered connected different OSes. 

One measurement I've utilized Linux is straight from a USB drive. Not only is this nan easiest measurement to instal Linux, but it's besides a viable measurement to usage Linux.

With a instrumentality for illustration uNetBootin, you tin burn an ISO to a USB drive specified that it's imaginable to footwear to Linux, bypassing nan installed OS connected a computer.

It's very handy.

But what are nan pros and cons of utilizing Linux successful this way? 

Pros

First, let's talk astir nan affirmative aspects of Linux connected a USB drive.

You'll ever person Linux pinch you

I ever for illustration to person a Linux OS pinch maine because I ne'er cognize erstwhile I'm going to tally into a business wherever I request Linux and nan only OS successful show is Windows. When those situations occur, I tin propulsion retired my trusty USB drive, insert it into nan computer, reboot, and footwear into Linux. 

I tin past do what I request to do and, erstwhile I'm finished, I tin unopen down nan PC, region nan USB drive, footwear nan system, and we're backmost wherever we started.

Try earlier you bargain

Unless you're utilizing Linux connected a virtual machine, installing nan open-source OS is usually done via a USB drive. Because of this, you tin pain an ISO to a USB drive, reboot nan system, footwear into nan USB drive, take nan Live action (if necessary), and trial nan distribution you've chosen.

If you don't for illustration that distro, commencement again pinch a different one. 

Rescue and betterment

I've utilized Linux arsenic a rescue and/or betterment instrumentality for years. When thing goes incorrect pinch a PC (whether it's moving Linux aliases Windows), I tin footwear up a Linux USB thrust and (most always) either lick nan problem aliases rescue nan files/folders I need. You tin do this pinch a modular Linux distribution, aliases 1 designed specifically for rescue and betterment (such arsenic SystemRescue).

Isolation

Let's opportunity you person Windows installed connected your PC and you request to do thing that requires a spot much privateness and information than offered by nan Microsoft OS. You tin ever footwear Linux from a USB drive, do what you request to do, and reboot nan instrumentality backmost into Windows.

Even better, you tin footwear into Linux, disconnect from nan network, and you person a pseudo air-gapped PC.

When utilizing Linux from a USB drive, nan OS is isolated from nan installed OS (Unless you equine nan soul thrust to Linux).

Cons

Now let's look astatine nan antagonistic aspects of utilizing Linux via a USB drive.

You person to configure it for persistent retention

If you want to prevention files from Linux connected your USB drive, you'll request to group up persistent storage, and that's not ever truthful easy. The easiest method of doing this is pinch nan likes of nan Rufus bootable USB creator. Not only tin you pain your ISO to nan USB thrust pinch this tool, but you tin besides create persistent storage.

With persistent storage, you tin prevention documents aliases different information while utilizing Linux from a USB drive. With that information saved to persistent storage, erstwhile you adjacent footwear Linux from nan USB drive, nan information will still beryllium location and accessible. Without persistent storage, thing you prevention from Linux connected nan USB thrust will beryllium mislaid astatine nan adjacent boot. 

You'll request a reasonably ample USB thrust

Sure, you tin tally Linux connected a smaller USB drive, but if you want it to activity good (especially if you adhd persistent storage), you'll want a USB thrust that's astatine slightest 64GB. With thing smaller, you tally nan consequence of Linux not moving arsenic good arsenic imaginable and moving retired of persistent retention space.

Getting full-disk encryption is very challenging

If full-disk encryption is simply a necessity for you, past moving Linux from a USB thrust is astir apt not nan champion option. The process of getting full-disk encryption for Linux connected a USB thrust is rather challenging. 

Creating encrypted persistent retention connected a USB for Linux requires a batch of work. The different action would beryllium attempting to instal Linux straight to nan USB thrust and enabling full-disk encryption via nan OS installer.

USB drives don't past arsenic agelong arsenic SSDs

Sadly, USB drives simply cannot lucifer nan longevity of a modular SSD drive. Granted, flash retention tin past up to 10 years, but that depends connected really it's used. The logic is that this type of retention is constricted by constitute cycles. 

Also: I tested nan world's smallest 1TB SSD drive, and it's a game-changer for activity travel

If you're utilizing a USB thrust to simply shop data, you tin expect to get astir 10 years retired of that drive. If, however, you're utilizing it to tally a unrecorded Linux instance, it tin eat done those constitute cycles overmuch faster.

There are different issues involved, specified arsenic temperature. An soul SSD is going to typically beryllium successful a much accordant temperature, whereas a USB thrust will beryllium carried pinch you, near successful basking cars, possibly dropped successful snow, etc. 

Suffice it to say, I would expect a USB thrust that runs Linux to past betwixt 2-5 years. Granted, that's a beautiful agelong time, but if you usage persistent storage, you'll want to make judge to backmost that information up.
