Question 1

Is an SSD or HDD cheaper per TB in 2026?

Accepted Answer

HDDs are still much cheaper per terabyte for bulk capacity. On Amazon.com today an SSD typically costs several times the price per TB of a 3.5-inch hard drive. This calculator reads live median prices for both, so it shows the exact multiple for the capacity you enter rather than a stale rule of thumb.

Question 2

When is it worth paying for an SSD over an HDD?

Accepted Answer

When the job rewards speed rather than raw capacity. A boot or OS drive, a NAS cache, a video scratch disk, or a database all benefit from SSD throughput and IOPS enough to justify the price premium. For a media library, backups, or an archive, the hard drive wins on cost per terabyte and the SSD premium buys you little.

Question 3

How do I calculate the SSD-vs-HDD cost break-even?

Accepted Answer

Take the capacity you need in terabytes and multiply it by the current price per TB of each drive type, then compare the totals. This tool does that live: it projects your target capacity at the median price per TB across every trustworthy SSD and 3.5-inch HDD listing on Amazon.com and shows the dollar difference plus a buy link for the best-value drive in each category.
