This is less related to the used hot swap drive bay or disk, it's depends more on the clothes or flooring. IMO we shouldn't wear an antistatic wrist strap, unless the used gear is connected by galvanic isolation. I don't have my computer gear connected by isolating transformers and I don't trust fault current circuit breakers, so IMO wearing an antistatic wrist strap is not without a risk, let alone that it is annoying to put on an antistatic wrist strap, just to replace a disk. > 2) I have been using an external hot swap drive as backup for >over a decade. _Never_ had problems I could reasonably attribute >to static discharge. Actually static discharge never caused an issue for me, without ever wearing an antistatic wrist strap and apart from this I always had good luck with very good operating fault current circuit breakers. Nevertheless, you never know.
