Apa itu ssd dan hdd
Some external hard drives, however, have protection to address this problem (such as Rugged discs, water-resistant, dust-proof, shock-and-fall). (4) Durability and resistanceĪ SSD has no moving parts, so it is more resistant to impact when compared to HDD. Whether you use computer for leisure, school and work, speed is still a criterion of choice for a computer. A computer with a SSD will start in less than a minute (a few seconds for most) and be faster than HDD for starting and running applications as well as for transferring files. The transfer speed is the strong point of the SSD. As for SSDs, the first prices offer a storage capacity of around 256 GB. 500 GB to 1TB HDD is commonplace and is considered a basic capability. (2) Storage capacityĪlthough there are several high capacity SSD (up to 16 TB), they remain scarce and costly. On the other hand, it will take about 300 euros for an SSD of the same capacity. An internal 2.5" 1TB HDD costs on average between 50 and 70 euros. SSD are more expensive than HDD in terms of Euro per gigabyte. But each has its own specific characteristics (storage capacity, price, speed, etc.). SSD and HDD do the same job: they can start your operating system, store your applications and your personal files. However, the HDD have generally higher storage capacity for SSD. The SSD offer improved durability and superior performance to HDD drives. SSD made of integrated circuit assemblies by the control unit and storage unit (FLASH chip, DRAM chips). SSD, also know as solid state drive (and non-mechanical HDD) memory to store information.
These platters have magnetic heads which move with an actuator arm to read and write information.
Inside the HDD there are sectors located on tracks, which are stored on rotating platters. These disks internal or external to the computer, consist of one or more mechanical disks that read and write information on the disk. HDD, know as hard disk drive are the most commonly parts for desktop computers. The hard drive of a computer plays the essential role of storing and retrieving information. These types of hard disks can store a large number of files, music, videos and images because of their high storage capacity. The hard drive is a key component of laptop and desktop computers.
