Why does Samsung recommend USB HDD over USB memory for the TV's PVR function?

* Please note, this section is designed to give you basic product troubleshooting information, also refer to your user manual for more information.

USB HDD (Hard Disk Drive) operate between 5400rpm (USB powered) - 7200rpm (AC powered), this means that they have a higher constant read and write, this is essential for the recording function, USB memory sticks on the other hand fluctuate greatly in their reading and writing capabilities, this makes them unreliable when it comes to purchasing a USB storage device for the TV's recoding function.
