How to increase HDD performance?
Seagate began shipping HAMR ( heat-assisted magnetic recording ) hard drives a few days ago , which was introduced back in November 2020, and has expanded its MACH.2 dual drive HDD testing program , which provides twice the performance compared to conventional hard drives. The company is confident that this set of technologies will increase both the capacity and performance of hard drives in the coming years.
Hard drive capacity is a very important parameter, but if capacity, write density and linear read / write speed increase, random read / write IOPS per terabyte decrease, which negatively affects the data center segment. To improve sequential read / write speed and IOPS per terabyte, HDD manufacturers are developing new models with two independent drivesthink of them as two separate hard drives in one 3.5 "enclosure. And Seagate became the first HDD manufacturer to introduce Multi-Actuator Technology (MAT) at the end of 2017, and in 2019, selected partners of the company received test samples of the corresponding Exos drives 2X14 MACH.2 Unfortunately, it is still unknown when Seagate's MACH.2 HDDs will be commercially available, hopefully in 2021.
"Seagate's first dual-drive technology has attracted the attention of a broad base of users looking for high-capacity, high-performance drives for scenarios such as content delivery," said Dave Mosley, CEO of Seagate. "Today we are increasing shipments of dual-drive drives, and this share will grow as capacity increases."
