Technologies behind hard disk drives (HDDs) have been well tested and are currently well known, as this type of disk has been present on the market for more than 50 years. Throughout this long period of time HDD technologies have been steadily developing, increasing the capacity, decreasing the physical size, and becoming more sustainable and affordable.
Modern Enterprise HDDs offer:
- Up to 20TB in the typical 3.5” form-factor
- The workload of up to 550TB/year and 24/7-Operation
- Yearly failure rates as low as 0.35% (equivalent to a Mean-Time-to-Failure MTTF of 2.5M hours)
