How TerabyteWise Ranks Storage by Value

terabytewise.com is an independent site for the US and Canada that answers one practical question: what is the cheapest storage by the terabyte right now, and which drive should you actually buy. We rank NAS-rated hard drives, DIY TrueNAS and Unraid build parts, and shuckable external drives by live price per terabyte, on Amazon.com in USD and on Amazon.ca in CAD.

Most of this is otherwise scattered across Reddit threads, forum posts and stale spreadsheets. We pull it together with live pricing so you can decide in one place. We only recommend NAS-rated CMR drives for RAID pools, we track post-shuck $/TB against buying an internal drive, and we give honest caveats on warranties and recertified stock.

Prices and availability are synced from the Amazon Product Advertising (Creators) API into our own database several times a day and served from there, so pages load fast and never call Amazon at request time. The last update time is shown on every page.
