The best WD SSD depends on whether it goes in a desktop, a thin laptop, a NAS or your bag, because Western Digital builds a separate color line for each job. This guide matches every color to the buyer it fits.
We compared interface, rated read and write speed, capacity, endurance focus, bundled software and warranty for each Western Digital drive. We checked each Amazon listing on October 24, 2026 and used only the specs the maker or seller lists. We do not list exact prices because Amazon prices change in real time. Use the buttons to see the current price and availability on Amazon before you buy. Scores are our editorial scores out of 10, not Amazon customer ratings.

In-Depth Reviews
1. What the WD SSD colors mean
Western Digital uses Blue for mainstream PC drives such as the WD Blue SN5000, Red for NAS drives such as the WD Red SN700, and Green for slim, entry-level drives. The My Passport name covers portable storage.
Match the color to the device first. A NAS drive is tuned for endurance and many users, while a Blue drive is tuned for everyday desktop and laptop speed.
2. NVMe or SATA WD SSD
