dd over usb3 is extremely slow

gb flag

I'm using dd to wipe an old hard drive. It starts out doing about 70MB/s, but at around 6GB it slows to 1.3MB/s. I've read about the cache filling up, but i think usb3 can write faster then 1MB/s.

"dd if=/dev/urandom of=/dev/sdd bs=1M status=progress"

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
