From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is the largest file transfer you have ever done? (startrek.website)

I'm writing a program that wraps around dd to try and warn you if you are doing anything stupid. I have thus been giving the man page a good read. While doing this, I noticed that dd supported all the way up to Quettabytes, a unit orders of magnitude larger than all the data on the entire internet.

This has caused me to wonder what the largest storage operation you guys have done. I've taken a couple images of hard drives that were a single terabyte large, but I was wondering if the sysadmins among you have had to do something with e.g a giant RAID 10 array.

Manually transferred about 7TBs to my new Rpi4 powered NAS. It took a couple of days because I was lazy and transferred 15 GBs at a time which slowed down the speed for some reason. It could handle small sub 1 GB files in half a minute otherwise.

Could the slowdown be down to HDDs that cache on a section of - I think it's single layer? - and slowly rewrite that cache onto the denser (compound layer?) storage?
