Flashdrive Longevity??

05/22/2019 10:55 PM

We have a number of workstations widely separated, no way to network them all.

Each one has a flashdrive to automatically backup critical data every evening. While most work just fine, we find others that will not complete backups. Sometime because they just are no longer recognized (unplug and re-plug and they are back). Other times I feel them and the are warm to the touch, sometimes fail so the computer will not boot due to memory issues from said drive. Then I just replace - with a new bigger drive and all is good.

Some of our techs abide that they are only good for X number of read/writes. Others say the quality of the flashdrive determine the lifetime.

Looking for any/all thoughts. While I cannot re-design the backup system, I'm just looking for information on flashdrives…...

"Some of our techs abide that they are only good for X number of read/writes. Others say the quality of the flashdrive determine the lifetime."

Both statements are not mutually exclusive and particularly the first statement is correct.

Same thing happened to me. But, I left the cap for it at a computer lab once. After awhile it got filled with lint/junk. It worked fine after I cleaned it. Those caps are easy to misplace/lose.

Open the flash drive and look at the memory chip. Look at the manufacturer's data sheet for that chip. It will tell you what the minimum number of writes the chip is rated for. That will give you a basis for comparing drives and how long to expect them to last.

This certainly part of the issue!

The drives are left in all the time since most backups are done after midnight. I'm guessing this is why I'm feeling them warm??

Do you leave them plugged in and can other ports be used in a storm?
