Hard drives present the lowest price per storage capacity, making them perfect for backups. Yet, in terms of performance, hard drives are inferior to solid-state drives.The above hard drives have an internal Data Transfer Speed of around 180Mb/s. And practical Random Seek Read Write is usually around 15Mb/s. That mechanical limitation presents a bottleneck with an external SATA6 Interface connection speed of 6Gb/s.

Comparison Solid State drives Data Transfer Speed start from 500Mb/s as well Random Seek Read Write achieving over 5000Mb/s for a modern SSD with NVMe interfaces.

Hard Drive Reliability

Western Digital consistently ranks as the most reliable hard drive manufacturer in independent data. Backblaze, which monitors over 300,000 drives in its data centres, recorded WDC drives at a quarterly annualised failure rate (AFR) of just 0.0% to 0.85% from 2022 to 2024 - the lowest of all manufacturers tracked and well below the industry average of 1.57% for 2024. The WD Red 10TB is rated for 24/7 NAS operation with vibration compensation, making it the right choice for always-on backup and media storage. The WD Blue is the standard for desktop and laptop hard drive replacements where cost per gigabyte matters most.

We stock these reliable Western Digital hard drives at our Brookvale workshop on Sydney's Northern Beaches. All terabyte hard drive prices above include GST and apply when supplied with an on-site service such as computer repair or data recovery.
