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)
File size: 5.9 MB
Conclusion
To overcome the performance limitations of data storage based on HDD drives several types of Open-E JovianDSS caching approaches can be deployed so as to help in accelerating both the read and write operations. First of them is using the SSD or NVMe-based Read Cache to improve the speed of read operations, and the second is the Write Log to do so with the write operations as well.
