Frequently Asked Questions
Are HDDs still worth buying?
Yes — for bulk storage, HDDs deliver far more capacity per dollar than SSDs. A 4TB HDD costs roughly the same as a 1TB SSD. They're ideal for backups, media libraries, and NAS systems where raw speed is less critical than cost per TB.
What is SMR vs CMR and which should I buy?
CMR (Conventional Magnetic Recording) is the reliable choice for most workloads, especially NAS and frequent writes. SMR (Shingled Magnetic Recording) is denser and cheaper but writes slowly under sustained load. Always prefer CMR for NAS, backup drives, and anything write-intensive.
