Abstract
(EN)
A logic partition method for a solid state drive and a device, the method comprising: obtaining the preset capacity of a logic partition (S10); calculating a required total number of units according to the preset capacity and the unit capacity of a logic unit (S11), wherein the logic unit is the basic compositional unit of the logic partition; counting the idle logic units in a solid state drive, and making a record (S12); and obtaining target idle logic units, the number of which matching said total number of units, and mapping the target idle logic units into the logic partition (S13). Hence, with the present method, logic units may be used in the same way in a situation where the logic units are not continuous, thus the discontinuous logic units are mapped and combined into a compositional part of a logic partition so as to avoid wasting space. Therefore, the space use efficiency of the solid state drive is relatively increased with the present method so as to guarantee that the solid state drive exhibits higher availability.

L'invention concerne un procédé de partition logique pour disque dur électronique et un dispositif, le procédé consistant à : obtenir la capacité prédéfinie d'une partition logique (S10) ; calculer un nombre total requis d'unités en fonction de la capacité prédéfinie et de la capacité unitaire d'une unité logique (S11), l'unité logique étant l'unité constitutive de base de la partition logique ; compter les unités logiques libres dans un disque dur électronique, et effectuer un enregistrement (S12) ; et obtenir des unités logiques libres cibles, dont le nombre correspond audit nombre total d'unités, et mapper les unités logiques libres cibles à la partition logique (S13). Ainsi, avec le présent procédé, des unités logiques peuvent être utilisées de la même manière dans une situation où les unités logiques ne sont pas continues, par conséquent les unités logiques discontinues sont mappées et combinées en une partie constitutive d'une partition logique de façon à éviter un gaspillage d'espace. En conséquence, l'efficacité d'utilisation de l'espace du disque dur électronique est relativement augmentée avec le présent procédé, de façon à garantir que le disque dur électronique offre une plus grande disponibilité.

一种固态硬盘的逻辑分区方法及装置,该方法包括:获取逻辑分区的预设容量(S10);根据预设容量以及逻辑单元的单元容量计算所需的单元总数(S11);其中,逻辑单元为逻辑分区的基本组成单元;统计固态硬盘中的空闲逻辑单元并进行记录(S12);获取数量与单元总数相匹配的目标空闲逻辑单元,并将目标空闲逻辑单元映射为逻辑分区(S13)。可见,本方法在逻辑单元不连续的情况下同样能够使用该逻辑单元,进而将不连续的逻辑单元进行映射组合成为逻辑分区的组成部分以避免空间的浪费。因此,本方法相对提高了固态硬盘的空间利用效率,进而保证了固态硬盘具有更高可用性。
