Which would be faster at storing backups; a portable HDD or a flash drive if both are connected to a USB 2.0 port?
Secondly, which would have the longer lifespan?
(Both are USB 3.0 devices, but the port used is only USB 2.0)
It's a backup of a portion of the HDD in my NAS. It only has a single USB 2.0 port for backup to another device. I've been using flash drives for years, but they eventually all fail at some point. I was wondering if using a portable drive would be faster and have a longer lifespan.
