  • High Bandwidth – Provides 3X the throughput of enterprise SATA SSDs
  • Mitigate SATA Sprawl – Enable potential 3:1 server consolidation
  • Low Thermal Profile – 10W average power compared to 25W solutions

SATA SSDs have long been used in data centers and cloud storage. But as capacity needs grow along with the necessity to access data with minimal latency, the adequacy of the interface bandwidth between the host and the drive comes under scrutiny. With no announced evolution of the SATA standard beyond SATA 3.x (6Gbps), the use of SATA SSDs in the cloud has reached performance limits. While capacity and bandwidth can be scaled by supplementing more SATA drives, they will come at the cost of increased floor space and lower PUE (Power Usage Effectiveness). The sprawling effect of SATA SSDs can be mitigated by the use of Ultrastar DC SN620 NVMe-compliant SSDs. By delivering 3x the bandwidth of enterprise SATA SSDs, like CloudSpeed Gen. II SATA SSDs from the SanDisk brand, Ultrastar DC SN620 SSDs can yield server consolidation benefits as much as 3:1.
