High-capacity hard drives of 20TB and above are for serious archives, media servers and dense NAS builds. These are enterprise CMR drives, and while the sticker price is high, the price per terabyte is often the lowest of any storage. This table ranks 20TB+ drives on Amazon.ca by live price per terabyte, so you can find the most capacity per dollar at the top end. The 14-18TB band is sometimes better value; check our capacity pages too.
