Our pick

Seagate BarraCuda 2TB

Choose the Seagate BarraCuda 2TB for bulk files in a laptop with a compatible 7mm 2.5-inch SATA bay.12

Why this one

  • It doubles the 1TB model’s capacity in the same thin 7mm case, adding room for a larger file library without needing a taller bay.123

Read the review

Before you buy: Choose this SMR drive for bulk files updated occasionally. For frequent large writes, choose a suitable SSD instead, and keep a separate backup.2

Other contenders

  • Seagate BarraCuda 5TB
