The hard drive operates at a speed of 7,200 revolutions per minute (RPM), which is faster than the standard 5,400 RPM speed of most laptop hard drives. In this article, we will provide a detailed description of the ST9500420ASG hard drive, its specifications, features, and benefits.
Storage Capacity
ST9500420ASG has a storage capacity of 500GB, which is a large storage capacity suitable for storing various types of files, including documents, photos, videos, music, and applications. The storage capacity is the amount of data that the hard drive can store, and it is usually measured in gigabytes (GB) or terabytes (TB). The 500GB storage capacity makes it an ideal choice for users who require a large storage space for their data.
RPM Speed
The RPM speed of a hard disk drive refers to the number of revolutions per minute that the disk spins. A higher RPM speed means that the drive can read and write data faster. ST9500420ASG operates at a speed of 7,200 RPM, which is faster than the standard 5,400 RPM speed of most laptop hard drives. The faster RPM speed ensures that the hard drive can access data more quickly, making it ideal for users who require fast data access.
Data Transfer Rate
The data transfer rate of a hard drive refers to the speed at which data can be transferred to and from the drive. ST9500420ASG has a data transfer rate of up to 3 Gigabits per second (Gbps), which is the maximum data transfer rate provided by the Serial Advanced Technology Attachment (SATA) interface. The fast data transfer rate ensures that the hard drive can transfer large files quickly and efficiently, making it ideal for users who frequently transfer large files.
Form Factor
The form factor of a hard drive refers to its physical size and shape. ST9500420ASG is a 2.5-inch form factor hard drive, which makes it suitable for use in laptops and other portable devices. The small form factor of the hard drive allows it to fit into small spaces, making it an ideal choice for users who require high-capacity storage in a small form factor.
Shock Tolerance
The shock tolerance of a hard drive refers to its ability to withstand physical shock and vibrations without losing data or suffering damage. ST9500420ASG has a shock tolerance of up to 350G while operating and up to 1000G when not operating. This means that the hard drive can withstand accidental drops and impacts without losing data or suffering damage, making it a reliable choice for users who require a durable hard drive.
Power Consumption
The power consumption of a hard drive refers to the amount of power it requires to operate. ST9500420ASG has a low power consumption, which makes it ideal for use in laptops and other portable devices. The hard drive consumes an average of 2.5 watts of power when in operation and 0.5 watts when in idle mode. The low power consumption ensures that the hard drive operates quietly and does not drain the battery of the device.
Cache Size
The cache size of a hard drive refers to the amount of high-speed memory that is built into the hard drive. The cache memory is used to temporarily store frequently accessed data, which allows the hard drive to access the data more quickly. ST9500420ASG has a cache size of 16MB, which is a large cache size compared to other laptop hard drives. The large cache size ensures that
