Add reliable, high-capacity storage with internal hard drives for desktops, servers, NAS units and surveillance systems. We stock Seagate, Western Digital and Toshiba drives from 1TB up to 20TB+, including drives purpose-built for NAS (NAS-rated for 24/7 operation), CCTV/surveillance, and enterprise workloads. Choosing the right drive matters — surveillance drives are tuned for constant write loads, NAS drives for always-on multi-bay reliability, and enterprise drives for heavy server duty. If you want speed for your operating system and apps, pair an HDD for bulk storage with an SSD. All drives are genuine, brand-new stock with manufacturer warranty, priced in NZD including GST and delivered across New Zealand.
When shopping for a hard drive, capacity is typically the first consideration. For basic desktop storage, 2-4TB drives offer good value, while professional users might require 8TB, 10TB or even 16TB models. Consider what you'll be storing – large media files, backups, or business data – and choose accordingly.
The intended use of your hard drive should guide your purchase decision. Standard desktop drives are designed for everyday computing, while specialized drives like WD Purple are optimized for surveillance systems with 24/7 operation. NAS-specific drives like the WD Red Plus series are built for reliability in network storage environments, with vibration protection and workload ratings suited to multi-drive systems.
Connection type is another important factor. Internal drives typically use SATA connections, while external drives offer USB 3.0, USB-C or Thunderbolt interfaces for plug-and-play convenience. For professional users in Wellington, Auckland or Christchurch requiring the fastest possible transfers, consider Thunderbolt 3 options like the G-Technology G-DRIVE. Remember that all hard drives at Comsys come with manufacturer warranty and our 30-day returns policy, giving you peace of mind with your purchase.
Desktop drives suit single-PC use. NAS drives (e.g. WD Red, Seagate IronWolf) are built for 24/7 multi-bay operation in a NAS. Surveillance drives (e.g. WD Purple, Seagate SkyHawk) are optimised for the constant write load of CCTV recording. Using the right type improves reliability and lifespan.
It will often work, but it's not recommended. NAS and surveillance systems run continuously, and purpose-built drives are designed for that duty cycle with firmware tuned for the workload — giving better reliability and warranty cover in those applications.
It depends on your use: a few TB suits general file storage; CCTV and NAS setups often need 8-20TB+ depending on cameras, retention and number of users. For surveillance, match the drive to your NVR's recording days and channel count.
SSDs are far faster and best for operating systems, apps and laptops. HDDs offer much more capacity per dollar, making them ideal for bulk storage, backups, NAS and surveillance. Many systems use both — an SSD for speed and an HDD for capacity.
Yes — all drives carry the manufacturer's warranty, which varies by range (consumer, NAS and enterprise drives often differ). Check the product page for the exact warranty term.
