It's called an SD card and they are very common.
No sir, that is not USB, I didn't stutter in my post! Different interface entirely.
Actually it's not. SD uses USB under the hood. It just moves the connection point. SD is the better design of USB.
-
That's why SD cards and USB sticks show up the same as block devices... because they are the same.
-
What do you want to use them for?

expensive block boot devices to make monthly clones of my XS servers.
-
Why do you want read only for that?
-
@Reid-Cooper said in Enterprise USB drives:

To ensure no logging goes back to the USB if it's is being actively used.

Why not just mount the FS read only if you want to block it entirely?

And how would you go about doing that, if you're using this device as a boot device for a hypervisor?
-
This is to run the hypervisor, with logging redirected to my graylog server, I have centralized logging.
The goal is "nothing on cheap drives" so just looking for a long life USB that can be used to make a bootable clone of the running USB drives.

I used an earlier model of that kangaroo drive when I was building out scripts to image computers. I used the write protect switch when I was learning how to script diskpart....

You still have to mount the volumes. Just use the read only options for your root volume, or put /var/log on a separate volume and mount it read only.

You can get usb thumb drive like things with an sd card slot. the SD card just sticks a bit out. We have a couple here.

SD cards survive the writes much better than USB sticks?

Will XS even boot from a read-only boot drive?

I think it would crash as it writes more than just logs to the boot device...

Right, I would think the same. So while I understand @DustinB3403 desire to keep XS from writing logs to the USB/SD card, write protecting it probably won't work.

That was just a thought, the important item here to take away is if you know of any "enterprise" grade usb's let me know.
-
Since I don't think there is a general use case for something like this, I don't know of any "enterprise class" USB sticks, or SD cards for that matter.
When you start worrying about these types of things, you replace them with SSD or HDD I would guess.

SD cards are generally higher quality, like SAS and SATA, it's convention not technology. The two are literally the same thing, just one has the adapter built on, the other does not. But SD cards have the ro/rw switch built on.

So here is one such model. http://store.kanguru.com/products/kanguru-ss3
We use them
Unless you have a VERY SPECIFIC NEED - avoid at all costs.
It's just a big, slow, exceptionally expensive USB drive that you accidently switch into RO and continually get frustrated with.
