A project to increase the throughput of HDDs without increasing the cost of production.HDDs, on low-end (a 2TB HDD has a price identical to a 256GB SSD, 40€), have a price 8 times smaller than a SSD but have 30 times less IOPS and 5 times less throughput. As the reading/writing is done on only one side of a platter (1 bit HDD) and it is not possible to increase the rotation speed of the disk or the areal density, bigger HDDs are becoming even slower to backup, for example, for a speed of 100MBps (7200 rpm HDD) it takes 52 hours to backup a disk of 18TB.To compete with SSDs on server market, HDDs have to increase their capacity to 100 TB by 2030 which, given the difficulty in increasing density, only is possible by increasing the number of platters...
