Can I safely use a HDD in a car?
192/24 for my vinyl rips (iPod only outputs 48/16).


The audio quality of vinyl discs is way below 48kHz 16 Bit due to the analogue and mechanic process - the "scratching" of the needle generates a relative high background noise level.

I strongly recommend using flash memory technology in a car instead of magnetic platters. While 2.5" notebook HDDs can take a bit more abuse, they are still senstive - shock can damage them quickly.

But audio needs low bandwidth so you can try to use cheap memory like USB sticks or SDHC/SDXC cards. No need to use expensive SSD.
