Seagate Enterprise Value HDD (Constellation CS) Review
30 April 2013
Summary: The Seagate Constellation CS is a drive designed specifically for enterprise organizations who are on a tight capital budget for low-priority data but don't want the risk of using consumer drives for enterprise workloads. Constellation CS drives offer the lowest per-gigabyte cost that organizations will find in the enterprise market, making them worthwhile to consider for deployment.
Cons: Capacity, Performance, Configuration, Reliability/Data Integrity, Power Management, Environmental, Special Features, Dimensions for 3TB (HxWxD): 26.1mm (1.028") x 101.85mm (4.010") x 147.00mm (5.787"), Weight: 626g/1.38lb (3TB), Warranty: 3 years limited, Tops out at 3TB
Summary: The Seagate Enterprise Capacity 3.5" hard drive line offers the top available capacity of 4TB, with several options ranging from SATA or SAS interface, to SED and FIPS security (SAS model only). The Constellation ES.3 also gets a bit of a performance upgrade over the ES.2 as well. Seagate quotes a 13% throughput gain; we saw a write improvement of 14.2% and a read increase of 12.7% in 128k sequential tests.
Pros: Faster than previous models in every single workload, Top capacity in the Enterprise SAS 7K class, Offered in both SAS and SATA interfaces, FIPS and SED security options
Cons: Capacities, Higher latency standard deviation in mixed workloads over ES and ES.2
Seagate Constellation.2 and Constellation ES.2 Hard Drive Review
31 May 2011
Summary: This review produced surprising findings in two areas: between the 6Gbps SAS and SATA interfaces as well as between the 2.5-inch Constellation.2 and 3.5-inch Constellation ES.2. It’s really a toss-up between SAS and SATA; each benchmark was a tug-of-war between them. Sometimes SAS would win out, sometimes SATA, and other times they would have identical performance - buy whichever interface your existing hardware supports.
Pros: Offered in SAS and SATA interfaces, High capacities for their respective form factors, Long warranty period
Cons: Available Capacities: 250GB/500GB/1TB, Interfaces: SATA 6Gbps, SAS 6Gbps (500GB/1TB only), Spindle Speed: 7200RPM, Cache: 64MB, Seek Time, Average Read/Write (ms): 8.5/9.5, Average Latency (ms): 4.16, Interface Ports: Dual, Idle Power Consumption: 3.85W, Random Read Operating Power Consumption: 6.4W, MTBF: 1.4 million hours, Available Capacities: 3TB, Interfaces: SATA 6Gbps, SAS 6Gbps, Spindle Speed: 7200RPM, Cache: 64MB, Seek Time, Average Read/Write (ms): 8.5/9.5, A...
Seagate Constellation.2: 2.5” Enterprise Hard Drive
21 March 2011
Conclusion: While the Constellation.2 is not a speed setter, it is not a sloth either. It is one of the fastest 7200RPM mobile drives and is able to compete against some of the 10K RPM drives. It also is faster than 3.5’’ 7200RPM drives on some applications. The drive has a very balanced read and write performance which means that regardless of the environment and task, it will offer the best performance.
Pros: Excellent performance, Balanced read and write, 2.5” form factor, 1TB capacity, 5 year warranty
Excerpt: Just last week we showed the Seagate Constellation.2 1TB SATA drive . The new Constellation.2 proved to be a worthy successor to the popular Constellation Series and it outperforms the first generation drive by a significant margin. Seagate also managed to double the capacity of the series while keeping the price of the new drives in line with the old offerings.
