What is Seagate constellation es 4TB?

Seagate recently updated its enterprise class lineup to increase the capacity available up to 4TB with the introduction of the Constellation ES.3 4TB drive. Delivering drives with larger capacities results in needing fewer drives to reach targeted storage capacities for a data center.

How many IOPS read from Seagate Constellation ES.3?

In our first workload with a 100% random 4K transfers, we measured 229 IOPS read from the Seagate Constellation ES.3 and 192 IOPS write. This was a steady improvement over both previous-generation models.

What is the capacity of a Seagate 3.5" hard drive?

The Seagate Enterprise Capacity 3.5" hard drive line is the newly rebranded family of high capacity hard drives of which the Constellation ES.3 is the newest member. The ES.3 is a 7,200 RPM, 3.5" enterprise hard drive with SAS or SATA 6Gb/s interface that’s offered in capacities up to 4TB. Seagate didn’t just bring a capacity bump to the line though. Compared to the prior generation Constellation ES.2, the ES.3 offers a sustained data rate of 175MB/s, up 13%, and Seagate has doubled the cache from 64MB in the ES.2 to 128MB in the ES.3.

What is the capacity of Seagate Enterprise 3.5?

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. Across the rest of our benchmarks we more or less found the ES.3 to top the prior generation drives in every test, showing Seagate has been able to eek out just that much more performance out of the platform that now offers 25% more capacity to boot.

How long is the average latency on a server?

In our Web Server test, average latency ranged from 34.87ms at 2T/2Q which scaled up to 1,151ms at 16T/16Q.

How much latency is 2T/2Q?

Looking at average latency in our File Server workload, we measured latency scaling from 33.41ms at 2T/2Q up to 1,189ms at 16T/16Q.

Does Seagate have a ES-3?

Seagate offers the Constellation ES.3 in a variety of options. Both SATA and SAS versions come in 1TB, 2TB, 3TB and 4TB capacities. The SATA version comes in both standard and SED iterations, the SAS models also add a FIPS security option, which is currently exclusive to Seagate. The ES.3 comes with a 5-year warranty.

What is a thermal pad on a hard drive?

Removing the circuit board from the hard drive body, we find multiple thermal pads used to dissipate heat from certain components into the HDD body. This allows the drive to act as one large heatsink, bleeding off excess heat with normal server airflow.

What is OLTP in banking?

OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Enterprise HDDs are uniquely well suited for the financial sector with their low latency and high random workload performance. Databases are the bread and butter of many enterprise deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.

What is the capacity of the Seagate Enterprise Capacity Constellation ES.3?

The Seagate Enterprise Capacity Constellation ES.3 provides a new enterprise-class SATA 6Gb/s 7200K HDD in a 3.5" form factor. These sixth-generation HDDs from Seagate are geared for those with the need for large, reliable bulk storage. The ES.3 is offered in capacities of 1TB, 2TB, 3TB, and the 4TB we are evaluating today.

How many IOPs per watt?

IOPS to Watts measurements are generated from data recorded during our test. The Constellation ES.3 delivers an average of 26 IOPS per Watt for 4K random writes , and 24 IOPS per Watt for 4K random read access.

What is 128k sequential speed?

The 128K sequential speeds reflect the maximum sequential throughput of the HDD using a realistic file size encountered in an enterprise scenario.

What does removing the PCB reveal?

Removing the PCB reveals a foam padding, drive controller and drive motor controller components. We can observe the two metal squares on the bottom of the HDD case that transfer the heat from the thermal pads into the case of the HDD.

What is 8k read and write speed?

8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.

What is consistent latency?

Consistent latency is the goal of every storage solution, and measurements such as Maximum Latency only illuminate the single longest I/O received during testing. This can be misleading, as a single ‘outlying I/O’ can skew the view of an otherwise superb solution. Standard Deviation measurements consider latency distribution, but do not always effectively illustrate I/O distribution with enough granularity to provide a clear picture of system performance. We use histograms to illuminate the latency of every single I/O issued during our test runs.

How fast is CrystalDiskMark?

CrystalDiskMark showed slightly higher sequential read transfers then our IOMeter tests using the 500MB test size. To compare performance between the slowest and fastest sections of the drive we used 600MB partitions positioned on the outermost and innermost locations on the platters. At its best the drive transfers data at about 130MB/s for read/write and at its worst it slows down to about 65MB/s read/write.

How many gigabytes is a Seagate Constellation ES?

512GB, 1 TB, and 2TB configurations offered in SAS and SATA interfaces with plenty of security and power savings options make the Seagate Constellation ES line a solid drive for high-capacity enterprise storage needs.

What is the speed of a Seagate Constellation ES 2TB?

The Seagate Constellation ES 2TB gives users solid performance with 129MB/s read and 133MB/s write transfer speeds on the 2TB SATA model. Seagate puts a strong emphasis on energy savings with the Constellation ES, offering PowerChoice to reduce power during slow or idle periods. In our tests with the drive in an active state we saw an idle power draw of 6.46w which was just under the advertised power draw of 7w. For users with security in mind Seagate also offers Self-Encrypting Drive (SED) as an option. Factor in that there’s also an SAS model and the Constellation ES has its bases covered.

What is the ES 3.5?

The Constellation ES is Seagate’s 4th generation 3.5" 7200 RPM enterprise-class hard drive. The drives come in 500GB, 1TB and 2TB capacities and support both SATA II and SAS interfaces. The Constellation ES isn’t all about high capacity and performance though; Seagate’s high on their power management and temperature tolerance for enterprise applications. The entire line also offers self-encrypting drive technology as an optional feature. With a spec sheet like this, it’s hard to imagine wanting anything else in a high-capacity enterprise-class storage solution.
