SATA – short for « Serial ATA », a designation for a computer bus interface used for connecting drives (HDD/SDD) or optical drives (CD, DVD etc.).
- SATA 1.0 – Throughput of up to 1.5 Gb/s (real bit rate of up to 150 MB/s)
- SATA 2.0 – Throughput of up to 3.0 Gb/s (real bit rate of up to 300 MB/s)
- SATA 3.0 – Throughput of up to 6.0 Gb/s (real bit rate of up to 600 MB/s)
HDD – (Hard Disk Drive) is the name for hard drives that store data onto rotating platters via magnetic recording. A « classic hard drive », the most popular type of disk in computers and servers.
They are divided into internal drives, which are used when assembling a computer or looking to expand its storage capacity, and external drives. External drives are suitable for storing and backing up data such as films, photos or music.
SSD – (Solid State Drive) a device for purely electronic data storage. The successor of magnetic hard drives which contains no moving mechanical parts. As a result, its advantages include higher resistance to vibrations and pressure changes, quieter running, lower power consumption and, above all, much higher speed
M.2 NVMe/SATA – M.2 is a new SSD format designed for internal mounting onto a PCI-Express bus or the high-speed SATA III interface. It is even smaller than a standard SSD with double the capacity and allows a number of advanced features. It is thus ideal anywhere where maximum performance and reliability at minimum space is paramount.
