It's spinning rust drive, that is going to be slower as main OS disc
than any sort of flash based medium. It would be OK for mass data storage.

It probably requires too much power, and caused a voltage dip. You'll
need to use a USB hub to provide the power most types of spinning rust
hard drive require.

Given the two points above, it's the wrong thing for a Raspberry Pi. If
you are happy with the its physical form factor, get a USB attached SSD.
