Detailed information
HDD
Traditional rotating or platter disks are ideal for applications where maximum affordability and high capacity play the most important role. These are, for example, cold storage, NAS solutions and others. Server HDDs are significantly more reliable than desktop HDDs. Also, many of them can achieve higher read and write speeds.
SATA
Serial ATA is the designation for a computer bus used to connect high-capacity devices - HDD and SSD disks. Nowadays, SATA revision 3.0 (SATA 6 Gb/s) is used. It offers a data throughput of up to 600 MB/s. SATA uses the older AHCI interface for communication, which is, however, sufficient and the most widespread.
Speed
A key parameter for hard drives is the speed of rotation of the platters, which for hard drives ranges between 5400 rpm - 15000 rpm (revolutions per minute). This directly affects the speed of the disk and, of course, its price. Nowadays, hard drives are increasingly being replaced by SSD solutions.
Capacity
The capacity of a disk often determines its usage. Large capacity HDDs are used for storing and backing up large amounts of data. A large-capacity SSD is useful, for example, in cases where multiple users simultaneously work with larger volumes of data in real time. On the contrary, SSD disks, which have a small storage space, are mainly used for the operating system and its fast running, or as a boot drive or for the hypervisor.
