I just got a [Sabrent USB 3.0 4 Bay 2.5" hard drive/ssd docking station](https://sabrent.com/products/DS-4SSD)

Tied it into my Raspberry Pi 4

I see the drives just fine…can I wipe /dev/sdc and /dev/sdd with this command simultaneously?

```auto

zram0 254:0 0 2G 0 disk [SWAP]

```

```auto
dd if=/dev/zero of=/dev/sdc of=/dev/sdd bs=1M status=progress

```

Will it attempt to wipe both drives at the same time…yeah it’s over slow USB 3.0 speeds…but is that the correct command??

You can only have one `of`  
But I think you can do it [this way](https://unix.stackexchange.com/questions/284480/dd-write-to-multiple-disks):

`sudo dd if=/dev/zero bs=1M status=progress | sudo tee /dev/sdc /dev/sdd > /dev/null`
