Hello everyone,
I was wondering if it would be advisable - because I know it can be achieved without much trouble - do host the wallet files on an external disc drive.
Will it stress particularly the disc drive in question?
Will there be any latency due to this?
Thank you for considering my questions!

No problem at all,its fine if you install wallets on second or third harddisk drive on your pc ive did this in the past and no issues at all as far as your pc is able to detect the external hard disk you will be fine,just make sure you dont leave your private keys on your hard disk because you will lose your coins if your hard disk died one day
And what about downloading it on my laptop for now and then moving it to the external disc drive?
