HDDs are magnetic data storage devices. HDD is still the most popular storage devices among a majority of users. The comparison given here would help you make the right decision in selecting drive as per your preference. In addition, there are even larger capacities for enterprise use. SSDs are also available in varying capacities and huge storages, but an SSD with a given capacity is much costlier than an HDD of nearly same capacity. A hard disk drive consists of a round plate or disk coated with a layer of magnetic material.

Data is stored on this magnetic film. Moreover, files are written sporadically across the cells. Making simultaneous access to every cell which means data is read at a faster speed. Some SSD drives known for their speed. While choosing a storage device the first thing that might strike your mind is the cost of the drive.

There are various factors on which reliability or the lifespan of drives depends, such as the amount of data written over the time, how you handle the drive, environmental conditions, age of the drive, etc.

This denotes that an SSD would start failing after it crossed the limit of number write cycles. HDD Rigs developed by Herrenknecht can be delivered in five different standard configurations.

All models have a control cabin, as well as their own power supply pack powered by a diesel or electrical engine, in sound-insulated container or onboard. Combinations of all types are possible and one of Herrenknechts' strengths. Fusions of Trailer and Modular Rigs or Compact and Crawler Rig merged with an electrical power unit are often made and jobsite approved.

Herrenknecht Rigs are defined by their pulling forces, which are betwen 80 and tonnes and 6, kN. Frame Rig: Their low weight and easy transport make Frame Rigs a reliable and economical solution. Without its own transport or motion system, the Frame Rig reaches the jobsite on a regular truck trailer.

A standard crane is sufficient for loading and unloading and for aligning the rig on the jobsite. Trailer Rig: The great advantage of Trailer Rigs is their extreme flexibility. Due to their low-weight design, they can be transported with standard semi-trailer trucks. A crane is not required, neither for setup and demobilization, nor for alignment and commissioning.

This makes Trailer Rigs particularly suitable for projects in which long distances in between several crossings are to be covered. Their robust and mobile crawler with its caterpillar tracks enables mobility and maneuverability on difficult terrain.

Modular Rigs can be dismantled into two or three modules and transported in standard freight containers. On site they are re-assembled. An optional, remote-controlled crawler adds further mobility on the jobsite. Compact Rig: Short and compact designed rig optimized for smaller projects and inner city applications.
