BuyPerUnit vs PCPartPicker: Which Finds Better Storage Deals?
What BuyPerUnit Does
BuyPerUnit focuses on one specific metric: cost per unit. It calculates the exact $/GB for storage and RAM, ranking them so you can see which drive gives you the most capacity for your money across Amazon, Best Buy, and Newegg.
What PCPartPicker Does
PCPartPicker is the definitive tool for building custom PCs. It checks compatibility between parts (e.g., will this CPU fit this motherboard?) and tracks price histories across dozens of retailers for every component category.

When to Use PCPartPicker Instead
