Embodiment Construction

[0050] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] At present, mechanical hard disks can be divided into two types: LMR hard disks and PMR hard disks. LMR hard disks are horizontal (horizontal) magnetic recording hard disks, but because the magnetic particles of mechanical hard disks are arranged horizontally, the density is relatively low, and a single platter cannot hold too much dat...

Abstract

The invention discloses a performance testing method, device, equipment and product of an imbricated hard disk, and relates to the technical field of storage, the method comprises the following steps: issuing a state switching command to a to-be-tested hard disk, and determining switching completion information returned by the to-be-tested hard disk according to the state switching command; the state switching command is used for switching the states of all forced sequential write-in areas in the hard disk to be mechanical from empty to full; based on the determined switching completion information, performing a read-write test on the to-be-tested hard disk, and generating a performance test result of the to-be-tested imbricated hard disk; the read-write test is used for querying and checking at least one of identification, attributes and power consumption modes of the to-be-tested hard disk. The invention provides a scheme for carrying out the performance test on the SMR hard disk, and the accuracy of data transmission detection is ensured while the performance test efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of storage, in particular to a performance testing method, device, equipment and product of a shingled hard disk. Background technique [0002] Mechanical hard disks are classified into horizontal (transverse) magnetic recording (Longitudinal Magnetic Recording, LMR) magnetic disks and perpendicular magnetic recording (Perpendicular Magnetic Recording, PMR) magnetic disks. PMR hard drives can allow hard drives to store more data and greatly increase the storage capacity of hard drives. Among them, the shingled (Shingled Magnetic Recording, SMR) hard drives in PMR hard drives can greatly improve the storage density of disks. SMR hard drive technology can effectively reduce unit capacity. the cost of disk storage. [0003] Due to the shingled track structure of SMR hard drives, data written to a track may overwrite adjacent tracks. However, the current pass-through consistency check of other types of...
