What is Disck ? (click to see more info)

A hard drive is a type of mass storage device that stores and processes data.

Types of Disks

Disk HDD they write data on spinning magnetic platters. The rotational speed of the discs is 5400 or 7200 rpm. They are characterized by a large capacity, because on the market you can get 1 TB HDD drives up to 6 TB and more, which will have space for large files, saving computer games or tens of thousands of photos. One of the cons of HDDs is not very high performance, average drives have download speeds of 50 - 120 MB / s which isn't a lot in nowadays. Disk defragmentation can occur when it is at an angle after a long time, we connect it to the SATA connector.

Disk SSD is a solid state drive based on flash memory. This solution allows you to get a write and read speed of 250 to 1000 MB / s and more, which is quite a good result. With an SSD, the operating system starts up quickly and so do the applications you use. To the list of advantages, it is worth adding even lower energy consumption, which has a key impact on the extended battery life. Cons of SSD Disk is a limited number of data write cycles. This means that subsequent data writing to the disk wears out flash memory cells and reduces its life, we connect it to the SATA connector.

Disk SSD M.2 are solid state drives based on a new type of connector based on the PCIe 3.0 x4 bus, only motherboards with an M.2 connector can be connected to this drive. The M.2 drive achieves reading speeds of 2000 - 4000 MB / s and more. M.2 drives are a significant step up from previous solutions. The new interface allowed for the construction of much smaller media. M.2 drives are available in sizes 2230, 2242, 2260, 2280 (22 is the width of the drive in millimeters, and the remaining 2 digits are the length of the media in millimeters).

PCI-Express NVMe interface

The interface determines the type of connector through which the SSD connects to our computer. In the case of PCI-Express, we are dealing with a universal connector that allows you to transfer data at high speed. Drives with this type of connection, supported by NVMe technology, are characterized by very high performance and are an excellent option for demanding users. The immediate exchange of files between NVMe disks deserves a lot of attention. The wide offer includes devices from many different manufacturers.
