Surveillance hard disks are typically mechanical drives optimized for high write performance. On top of that, the disk manufacturers need to ensure 24/7 availability of these drives. Long term reliability is a major requirement which these drives need to meet, whereas traditional hard drives on an average operate only between 8 hours a day and up to 6 days a week. So, the entire workload will be at the maximum 10%-20%, and their performance will be flat to average. Therefore, they usually exhibit low mean time between failures.
Other primary KPI’s include low power consumption and lowest cost per Gigabyte. The surveillance hard drives also come with an annual subscription based data-recovery plans in case there is a drive failure.
