Costco offers its members the ioSafe Solo G3 3TB USB 3.0 External Hard Drive, model no. SK3TB, for $299.99 with free shipping ($0.10/GB). (Non-members pay a $15 surcharge.) That's tied with our May mention and the lowest total price we could find by $115. Sales tax is added where applicable. This drive protects against data loss in fire up to 1550° F for 1/2-hour and from full water immersion up to 10 feet for 72 hours. Offer ends October 7. (We incorrectly listed this as the 2TB model earlier today. Our apologies.)
