$239.99USD + Shipping. Cost/TB = $13.33 (before shipping) is the lowest I think I've seen, anywhere… generally I've bought anytime drive prices bottom out at $15/TB, so this really good price.
Reading reviews, it is a good drive. Cool feature is 512MB opti-nand which is built-in solid-state storage (consumer drives have 2MB 'cache'). Some reviews say the drive can be a bit noisy though.
5-year warranty, as opposed to cheaper drives that offer 2-year warranty.
B&H Photo Video compete with Prime Day so they have other deals too. I also bought the 13700K CPU from B&H Photo Video which is a steal. Now I need to find a cheap motherboard.
