What is a Seagate Constellation CS?

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. The Constellation CS offers that standards that enterprises look for – it’s a 7,200 RPM, 3.5-inch HDD that offers capacities that range up to 3TB. It goes even further though as it is also offered as an SED with Instant Secure Erase to keep data integrity high while making drives reaching retirement age easy to take out of operation.

What is 128k test?

It is a large block sequential test that shows the highest sequential transfer speed for a platter drive. Looking at the 128k performance of 100% write and 100% read activity, the Constellation CS 3TB measured strongly at 190066 KB/s read and 188698 KB/s write, which were solid marks in both read and write activity.

How many threads are in a benchmark hard drive?

Our enterprise hard drive benchmark process preconditions each drive into steady-state with the same workload the device will be tested with under a heavy load of 16 threads with an outstanding queue of 16 per thread, and then tested in set intervals in multiple thread/queue depth profiles to show performance under light and heavy usage. Since hard drives reach their rated performance level very quickly, we only graph out the main sections of each test.

What is SED encryption?

Organizations can select optional Self-Encrypting Drive (SED) models that feature Instant Secure Erase. The integrity of drive is thus unlikely to be compromised thanks to the encryption and the Instant Secure Erase feature that is able to render all data unintelligible in a matter of just seconds.

Available in 500GB, 1TB & 2TB capacities, you may choose from either a 3Gb/s SATA with 32MB Cache or 6Gb/s SAS 2.0 interface with 16MB Cache. The Constellation product line also offers a smaller 2.5-inch form-factor with lesser capacities (160GB or 500GB) and identical interface options.

What is iozone test?

Iozone tests the speed of sequential I/O to actual files. Therefore, this measurement factors in the efficiency of your machine’s file system, operating system, C compiler, and C runtime library. It produces a measurement which is the number of bytes per second that your system can read or write to a file. Here we simulate a 4GB sequential read.

What is a Tiotest?

Tiotest is a file system benchmark especially designed to test I/O performance with multiple running threads. Here we read 32 concurrent I/O threads, each 256MB in size.

What is a dbench?

Dbench is a filesystem benchmark that generates load patterns similar to those of the commercial Netbench benchmark, but without requiring a lab of Windows load generators to run. It is now considered a de-facto standard for generating load on the Linux VFS. Here we simulate the load of 1 client.

Is the Constellation 2.5 inch or 2.5 inch?

Side-by-side we can see how the Constellation 2.5-inch is slightly higher than a standard 2.5-inch drive. You’re not going to be able to squeeze this into a notebook or netbook PC, but then again why would you want to? As stated previously, Constellation drives are designed and intended for enterprise application. This of course doesn’t mean you couldn’t use it in a workstation or desktop PC though. Just be sure your chassis has 2.5 drive bays, otherwise a mounting bracket such as the SilverStone 3.5" to 2.5" Drive Bay Converter can be purchased from an online retailer for under ten dollars.

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.
