Best Hard Drives & SSDs (Price per TB)

Finding the best storage value requires looking beyond the sticker price. We calculate the true cost per terabyte for hundreds of HDDs and SSDs daily. Whether you need a lightning-fast Gen4 NVMe for your PS5 or a high-capacity drive for your NAS, our price-per-TB comparison helps you spot the best deals instantly.

SSD vs. HDD: Which do you need?

Solid State Drives (SSDs) are essential for operating systems, games, and applications due to their speed. Hard Disk Drives (HDDs) remain the king of cheap bulk storage, ideal for backups, media servers, and NAS setups.

NVMe vs. SATA

Modern NVMe M.2 drives communicate directly with your CPU via PCIe lanes, offering speeds up to 7,000 MB/s or more. older SATA SSDs cap out around 550 MB/s but are still excellent for game libraries and secondary storage.
