HDDs are experiencing increased competition from SSDs in many aspects, but remain the go-to solution for capacity applications. The two technologies are destined to co-exist in the datacenter, and caching and tiering solutions merge the positive aspects of both solutions to accelerate workloads, and provide robust storage capacity. Datacenters are evolving to accommodate both forms of media and leverage their respective strengths to deliver the best overall solution.
New architectures, such as the Open Compute initiative, and new VSAN architecture, are designed from a system level to rely upon both forms of media, furthering intertwining the two technologies. These approaches also offer administrators wide latitude in the type of solutions they deploy into their architecture.
The Seagate Enterprise Capacity 2.5 HDD v3 steps in and offers a big capacity boost for space-constrained server and NAS/SAN applications. The slim form factor provides flexibility to deploy the drives into a number of applications, and enhanced density and lower power consumption address several pain points in the datacenter.
The Enterprise Capacity touts an 18% increase in sequential workloads, and best-in-class performance for the 2.5" 7,200-RPM segment. In our sequential testing, we found that the Enterprise Capacity v3 delivers fast sequential speed, and performance in mixed sequential workloads actually beat out the Constellation ES.3. The Enterprise Capacity v3 performance came in second to the speedy 6TB Enterprise Capacity.
In random testing, the Enterprise Capacity 2.5 HDD v3 delivered tremendous performance that surpassed the other drives in the test pool. Random workload performance was incredibly impressive with 4k and 8k workloads, and the v3 also demonstrated impressive strength in mixed random workloads.
The Enterprise Capacity v3 delivered excellent performance in our OLTP, fileserver, and email server workloads. The Enterprise Capacity v3 also exhibited excellent latency characteristics in our random workload latency-to-IOPS comparisons that easily outpaced the larger capacity drives in the test pool.
The most impressive test results actually came during power testing. The Enterprise Capacity v3 delivered a massive win in idle power draw, and even under heavy workloads, the gap remained large between it and the competition. The radically lower power consumption in tandem with increased performance contributed to a big win in every IOPS-per-watt test. Even with expected lower sequential speed, the Enterprise Capacity v3 managed to score a win in IOPS-to-MB/s measurements.
The Seagate Enterprise Capacity v3 offers the features we have come to expect from enterprise-class HDDs, such as an available dual-port 12Gb/s SAS connection, SED and FIPS options, Seagate Instant Erase, support for the RAID Rebuild functionality, and a five-year warranty. Pairing high performance with low power consumption, and a hefty dose of capacity in a small form factor, creates a compelling offering with class-leading attributes, winning the TweakTown Editor's Choice Award for the 2.5" capacity segment.
