Hard disk drives are today's fastest permanent storage media and have a large capacity. For this two reasons they are the most used storage medium in computers and servers. When buying a new hard disk, there are three important things to consider: - The connection of the disk to the computer or other device you will be using it with has a big influence on the speed with which data can be read from/written to the disk. Make sure the connection of the disk you buy is compatible with your computer! - The rotational speed is also important for the speed with which data can be read from/written to the disk and determines the time it takes to find a file on the disk. - Last but not least, the storage capacity of the disk, i.e. the amount of data that can be stored on the disk.

Western Digital Ultrastar 7K4000. HDD size: 3.5", HDD capacity: 4 TB, HDD speed: 7200 RPM

Delivering Industry-Leading Quality and Reliability

HGST Ultrastar® 7K4000 is the world’s first 4TB 7200 RPM hard drive with a 2.0 million hours MTBF specification and backed by a full 5-year warranty. Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design, which has been field proven by top server and storage OEMs and Internet giants. Engineered for the highest quality, the Ultrastar 7K4000 is put through grueling design tests during development and must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime, eliminating service calls and minimizing TCO.

Increasing Capacity Density by One Third

To deal with the explosive petabyte (PB) growth, data centers require large amounts of efficient storage. Reducing W/GB without expanding floor space is vital to lowering operating costs. To meet these demands, Ultrastar 7K4000 delivers 33% more capacity in the same footprint at 24% lower W/GB than its predecessor, Ultrastar 7K3000. Now you can get 2.4PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U, 60-bay enclosures. Ultrastar 7K4000 dual port SAS is available in traditional 512, 520 and 528 byte sector size. Ultrastar 7K4000 SATA is an Advanced Format* drive, using 4096-byte sector size to provide enormous capacity earlier than otherwise possible for environments optimized for this technology. Advanced Format drives are backwards compatible with legacy 512-byte sector size by offering built-in 512-byte emulation through the SATA interface.

Combining 7200 RPM Performance and Granular Power Control

Operating at 7200 RPM, Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power and HVAC requirements. With five Advanced Power Management modes, the 7K4000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 2W during standby/sleep modes, freeing up precious headroom for growing enterprise needs.

Innovating for a More Sustainable Environment

The Ultrastar 7K4000, with its halogen-free design and power-efficient operation, minimizes environmental impact in the areas of product design, manufacturing, operation and disposal.

HGST Quality and Service

HGST’s Ultrastar 7K4000 extends the company’s long- standing tradition of performance and capacity leadership. The proven drive design enables high reliability and availability to customer data. Ultrastar quality, performance and world class technical support and service provides customers with a lower total cost of ownership over previous generations.

HGST drives are backed by an array of technical support and services, which may include customer and integration assistance. HGST is dedicated to providing a complete portfolio of HDD/SSD solutions to satisfy today’s monumental computing needs.

Most of our avid readers of course have at least one SSD in their desktop and laptop, but for large volume storage you're still relegated to conventional hard disks. It's almost become a negative connotation - 'conventional' - and it really doesn't do t...

The Hitachi Ultrastar 7K4000 4TB made its first appearance on Maximum PC back in September 2012, when a gaggle of them debuted in the Dream Machine. At the time, they were the only 7,200rpm 4TB drives available, so they fit right in among all the othe...
Good Huge capacity; fast, superlong MTBF.

We all know (or at least most of us) that hard disk drives are much slower than solid state drives and so using the second just to house the primary OS (operating system) is always the ideal scenario. However no one can deny the splendid price/capacity ra...

Bottom line Based on our results it's quite clear that SATA II and SATA III are not at all apart in terms of performance (at least not with hard disk drives) which actually makes sense since the maximum speed of SATA II can reach 300MB/s (3Gb/s). Still we can only of...

WD's VelociRaptor 1TB might be the fastest hard drive in the world, but it could also be the loudest. The new Scorpio Blue 500GB is a different kind of drive, a single-platter notebook model with ultra-low acoustics.
