Hard disk drives (HDD) are available in a range of sizes, from 500GB upwards, allowing users easy and affordable customisation of the storage space available on their PC, laptop or server.
With more and more people building their own computers, and others gaining the confidence to customise their own devices, HDD remains a popular option, despite the increase in SSD sales. Hard drives also offer a secure backup as an alternative to a cloud service.
The advantages of choosing HDD over SSD
Internal and external HDD offers a much lower cost per GB than Solid State Drives (SSD).
HDDs have a much higher storage capacity than SSD. HDDs are available with several terabytes of storage, whereas SSDs become considerably more expensive over 2TB.
Availability of HDD is currently far better than SSD, with a much wider range of internal and external models available.
3.5” internal hard drives are designed for desktop/all-in-one PCs and entry-level DAS. They vary in price, based on capacity and read/write speeds.
2.5” internal hard drives are designed for laptops. They are very similar to the 3.5” drives, however, rpm and buffer tend to be lower.
When building a NAS solution, the type of hard drive that’s chosen to operate within the NAS has a significant impact on its performance. As data demands and user access increases, the performance of a low-cost hard drive will degrade, so it’s important to choose a drive that will meet demands.
NAS-optimised hard drives are designed with 24×7 use in mind and are optimal for continual use. They usually have a much higher capacity than standard HDD and are more reliable with cooling and anti-vibration technology.
NAS-optimised HDD is perfect for desktop RAID, server storage, and sharing, archiving and remote access.
External hard drives are formatted for use with either PCs or Macs, however many that are formatted for PC will also include a Mac driver. They’re more flexible than internal storage as they are portable and can be used across multiple computers. External hard drives range in capacity, from 500GB upwards, and pricing reflects the capacity and casing.
