How to choose this product

hard-disk-drive

A hard disk drive stores data permanently, contrary to random access memory (RAM). It is connected to the motherboard via an IDE, SCSI or SATA interface, or via a USB port, a firewire or an Ethernet port, in the case of an external hard drive.

Applications

Hard disk drives are used as mass storage devices in computers or in networks.

Technologies

These drives are composed of stacked platters kept in rotation by a motor. A series of intermediary magnetic heads read and write data on the platters' surface.

Drive capacity has increased significantly faster than speed, which is limited by mechanics. One terabyte is a common standard. Hard drives feature cache memory to compensate for data access delays.

In low-capacity applications, hard drives are more and more often replaced by electronic memories, such as SD cards or SSD disks. They are composed of flash memory, feature no mechanical parts and withstand vibrations better, but are more costly.

How to choose

The drive's capacity and data access speed are the main choice criteria. Furthermore, determine the required interface type, whether the disk should be external or not and the form factor. The harshness of the working environment also should be considered.

Advantages

- Mass data storage

Disadvantages

- Data access delays
