Founder, BuyPerUnit
Jon Levesque
Former Microsoft and DocuSign exec Jon Levesque built BuyPerUnit, a free price-comparison site that ranks storage hardware, TVs, and printer ink by cost per unit ($/GB for drives, $/inch for TVs, and $/page for ink) with daily pricing from Amazon, Best Buy, and Newegg.
Background
Jon Levesque is a former executive at Microsoft and DocuSign. BuyPerUnit grew out of personal frustration: sourcing hard drives in bulk meant opening 47 browser tabs and manually calculating which drive actually gave the most storage per dollar. The site automates that calculation across thousands of products and three major retailers, updated automatically twice a day.
The site launched in January 2026 and was covered by PC World and TechSpot the following month. Rankings are sorted purely by price per unit, cheapest first, with no paid placements and no vendor relationships that affect order. How prices are sourced, how the price-per-unit math works, and how articles are fact-checked are documented on the Methodology page.

“New PC storage shopping site only cares about price per gigabyte”
Former Microsoft and DocuSign exec Jon Levesque built a site that only cares about one number: how much you'll pay per gigabyte. The site tracks hundreds of drives across Amazon and Best Buy, automatically recalculating the per-gigabyte cost.

“New website helps you find the cheapest storage by cost per gigabyte”
Jon Levesque, a former executive at Microsoft and DocuSign, built a website that does not evaluate performance metrics — it only cares about price per gigabyte. The site was built after frustration sourcing hard drives in bulk meant opening dozens of browser tabs to manually calculate which drive gave the most storage per dollar.
