In other words, the RAID configuration consists of combining several independent hard disks into a single storage medium. More precisely, it federates physical hard disks into a single large logical volume, thanks to storage virtualization techniques.  <\/p><p>Although RAID is based on the aggregation of several disks into one or more &#8220;clusters&#8221;, its primary purpose is not to increase storage capacity. With the exception of RAID 0, the useful capacity of a RAID system is always less than the total size of the hard disks making up the system.   <br>It&#8217;s preferably the advanced features provided by storage virtualization that users will be looking for.<\/p><p>As its acronym indicates, the second founding principle of RAID is data redundancy, to limit data loss in the event of failure. Each system will also meet specific objectives, depending on the way data is distributed between the various disks, the interaction between them and the RAID parameters: increased read and write performance, fault tolerance, data availability and reconstruction, etc. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-576aa67\" data-id=\"576aa67\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5f62654 elementor-widget elementor-widget-image\" data-id=\"5f62654\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid.jpg\" class=\"attachment-large size-large wp-image-15146\" alt=\"laboratoire databack\" srcset=\"https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid.jpg 600w, https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid-300x300.jpg 300w, https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid-100x100.jpg 100w, https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid-150x150.jpg 150w, https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/recuperation-raid-160x160.jpg 160w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-bac93d5 elementor-reverse-tablet elementor-reverse-mobile elementor-section-content-middle elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"bac93d5\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-19f481d\" data-id=\"19f481d\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-bfb1ee3 elementor-widget elementor-widget-image\" data-id=\"bfb1ee3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"600\" height=\"839\" src=\"https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/databack-systeme-raid-2.jpg\" class=\"attachment-large size-large wp-image-15149\" alt=\"\u00e9tag\u00e8re de disques durs\" srcset=\"https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/databack-systeme-raid-2.jpg 600w, https:\/\/www.databack.fr\/wp-content\/uploads\/2025\/02\/databack-systeme-raid-2-215x300.jpg 215w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-432567c\" data-id=\"432567c\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-7dace90 elementor-widget elementor-widget-heading\" data-id=\"7dace90\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<span class=\"elementor-heading-title elementor-size-default\">Data recovery with RAID<\/span>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c2fcedf elementor-widget elementor-widget-heading\" data-id=\"c2fcedf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">RAID data recovery<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f0a2fc9 elementor-widget elementor-widget-text-editor\" data-id=\"f0a2fc9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Data recovery on RAID systems<\/strong> can be facilitated by data redundancy and parity.
