Most laptop hard drives are standardised at 2.5-inches, and you can install any brand.
Based on my terrible experiences with Seagate drives (four new ones all failed in less than a year) I cannot recommend them. WD drives have a better reliability record, as do Samsung & Hitachi drives.
Hey Phil thanks for the answer. About your Seagate drives, what was the reason of the failure and were you able to RMA them?
