Stable storage refers to a storage system that guarantees data durability and consistency even in the event of failures, ensuring that once data is written, it will not be lost. Disk storage, such as hard drives or SSDs, is a physical medium used to store data but does not inherently provide the same level of reliability or durability; it can be subject to data corruption or loss due to hardware failures. In essence, stable storage is a conceptual framework focused on data integrity, while disk storage is a tangible technology.
What else can I help you with?
What is stable storage?
Stable storage is a classification of computer data storage technology that guarantees atomicity for any given write operation and allows software to be written that is robust against some hardware and power failures. To be considered atomic, upon reading back a just written-to portion of the disk, the storage subsystem must return either the write data or the data that was on that portion of the disk before the write operation. Most computer disk drives are not considered stable storage because they do not guarantee atomic write; an error could be returned upon subsequent read of the disk where it was just written to in lieu of either the new or prior data.
The most important advantage of disk storage over tape storage?
disk storage-> direct data access storage tape storage -> serial data access storage
What is the difference between fixed storage and removal storage?
The best example of fixed storage in a computer is the hard disk. A frequent example of removal storage is a thumb drive / USB stick.
The smallest addressable unit of storage on a disk is called a?
The smallest addressable unit of storage on a disk is called a sector.
What are hard disk drive?
Hard disk drive is a storage device.its is a non-volatile storage device
What is disk failure?
Disk failure is about the malfunctioning of the disk storage device that is caused by booting the computer from the files. The disk storage device will no longer perform well and it is needed to be troubleshoot.
