Seagate Dual Read and Write Arm Drive Successfully Applied to Microsoft Cloud Service Cluster: Speed Catch up with SATA SSD

Under the impact of SSD, mechanical hard drives have obviously accelerated the pace of technological innovation, such as increasing the disk capacity density of SMR, EMAR magnetic recording technology, speed up the reading and writing speed of multi-literacy arm technology. Seagate has commercially traded a dual-literacy arm technology called Mach.2, according to reports, the first product 14TB Exos 2X14 hard drive has been deployed in Microsoft’s cloud server cluster, for Azure, Exchange and other services.

Aaron Ogus, Microsoft’s cloud architect, says tests have shown that exos 2X14 drives deliver twice as much throughput and IOPS.

Seagate Dual Read and Write Arm Drive Successfully Applied to Microsoft Cloud Service Cluster: Speed Catch up with SATA SSD

According to the previous official introduction, 8 disc 14TB continuous reading and writing speed 480-500MB/s, basically catch up with SATA SSD, compared to the ordinary 7200 rpm, SATA3 hard disk extreme value (235MB/s) directly doubled, even if the highest end of the standard 15K (15000 rpm), is faster than 60%.

Random reading and writing can reach a maximum of 160 IOPS, or about 10 IOPS per TB.

However, due to the higher prices, the broader application of Mach.2 products will take time to grow.
