Frequently Asked Questions
What is a good price per TB for a hard drive in 2025?
In 2025, a good price per terabyte for a consumer hard drive is around £12-18/TB for high-capacity drives (8TB+). Budget drives can go as low as £10/TB for used or renewed units, while smaller capacity drives (1-4TB) typically cost £20-30/TB due to lower economies of scale.
Should I buy a 3.5-inch or 2.5-inch hard drive?
3.5-inch drives offer better value per terabyte and higher maximum capacities (up to 24TB+), making them ideal for desktops and NAS systems. 2.5-inch drives are smaller and use less power, suitable for laptops or compact builds, but typically cost more per TB and max out around 5TB.
How long do hard drives last?
Consumer hard drives typically last 3-5 years with regular use. Enterprise drives are rated for longer lifespans. To maximise longevity, avoid physical shocks, ensure adequate cooling, and consider that drives with higher workload ratings (measured in TB/year) are built for heavier use.
What RPM should I choose for my hard drive?
7200 RPM drives offer faster read/write speeds and are best for primary storage or frequently accessed data. 5400 RPM drives are quieter, cooler, and more energy-efficient, making them ideal for bulk storage, backups, or NAS systems where speed is less critical.
