I Dont Want My Flash Usb to Immunzed Again
Some time ago I recollect I read on your site that flash drives can wear out. Now, I go on my flash drive in all the time because I'one thousand a writer and am ever backing things up on the computer and the wink drive, but I dislike having to close the flash bulldoze down, accept it out, just to reinsert it again after I take a break or run an errand. And I e'er leave it in when I run a full system browse because the flash drive will get scanned as well.
1. Is it harmful to the wink drive to just exit it plugged in 24/7, even when I put the figurer on standby for the night?
2. Why is information technology necessary to shut the flash drive down before removing it from the computer? Why tin can't I just pull it out when washed?
iii. And if I am right about flash drives wearing out, what wears out? As far as I can tell, they take no moving parts. And at what point should I consider replacing the flash drives I have?
These are very legitimate, but unfortunately very tough, questions to answer.
Wink drives exercise wear out, absolutely.
Simply exactly when a flash drive will wear out depends on so many things, it'southward impossible to give a specific answer. All I can say is "It depends."
I'll give you some guidelines that I'd follow on using a flash drive, were I in your shoes.
What wears out?
You're correct: there are no moving parts in a flash drive. A wink drive is so named because it uses what is chosen "flash retentiveness" — a type of solid country memory that retains its contents even later on power has been removed.
These devices wear out a picayune each fourth dimension something is written to information technology. Write to information technology enough, and somewhen writing to it will fail.
Exactly how chop-chop this type of failure happens depends primarily on ii things: the quality of the electronics and the number of writes. SSDs — solid state drives — are also a form of flash memory, but they're at present of high enough quality that they ofttimes outlast the estimator they're in, nether normal usage.
External USB flash or "thumb" drives? Not then much.
Why "safely remove"?
While it applies to both flash drives and traditional magnetic difficult drives, writing to a flash bulldoze is as well slower than reading from it, and then there'due south a performance benefit to buffering besides. Delaying writes until they are necessary maximizes speed and minimizes wear.
The "Safely Remove" function forces Windows to flush everything to the device. In addition, it checks for applications that have files open on the device that may exist in a similar partially-complete state.
Recent versions of Windows have changed their default behavior such that write caching isn't used as much as it was in the past, so "Safely remove" may not exist needed on all of your USB devices.
Should I exit it plugged in?
This is where my "it depends" really comes into play.
What information technology depends on is easy: is the device beingness written to — even occasionally — while it is left plugged in? I'yard not talking nigh your work; I'grand talking about other programs, similar Windows itself, anti-malware software, utilities, and other things that — on the surface — would take no reason to write to the device.
And nonetheless some practice. Mayhap.
If your computer is powered down — be it close downwards, hide or stand-by — there'due south no event. Nothing'south writing to the device when the machine is turned off.
If, yet, like me, you lot leave the motorcar on 24 hours a mean solar day, there's a small-scale run a risk.
Chance? How big a risk?
Information technology depends on several things.
It depends on the quality of the wink drive. It depends on what software you have installed on your machine. Information technology depends on how your USB or other connecting port is configured (some of the buffering might be turned off). Information technology depends on how long you plan to proceed your flash bulldoze. Information technology depends on how catastrophic information technology would be to you lot if it failed.
For many — perchance fifty-fifty most — in that location'll never be a problem. Most people might physically lose the flash drive earlier it wears out.
And the quality of wink retention is constantly improving. Equally I mentioned above, high-end flash memory used in SSDs have a applied lifespan that volition probably be longer than the machines in which they're installed.
Just that inexpensive flash bulldoze you picked up or were given for free? It'south probably not going to exist that aforementioned high quality. In fact, where it'll be on the quality scale — a scale that is constantly moving — is anyone's estimate.
But the risk is definitely in that location. Murphy'south Law being what it is, failure will happen when it'southward least expected and most inconvenient.
Mitigating risk
Here's what I recommend y'all practise: plan for failure.
Assume that sometime, out of the blue, a write to your flash drive will fail. Or that a later read volition fail.
In fact, that's an assumption you should brand well-nigh any storage device you use. Traditional hard disks also fail, ofttimes completely and without alert.
Brand certain that through some form of back-up, you can recover to a convenient spot.
Mayhap that means you need to save 2 copies every time (one to your laptop, one to the wink bulldoze). It sounds like that'south exactly what you exercise.
Perhaps it means that you don't employ a flash drive at all, just rather an online storage service like Dropbox, and so every time yous salvage the file information technology'south updated online. That's my preferred approach these days.
Perhaps information technology means deciding beforehand that information technology would be OK to lose a weeks' worth of work.
Regardless of which it is, make it a conscious decision and and so act on it accordingly.
