Why? Because of the way it\u2019s designed, those files would be instantly removed from both disks, as the disks are mirrored. Again, if one disk becomes corrupted by worms, Trojan horses, root kits, viruses or some other form of malware, this means that both disks become corrupted simultaneously. What about power surges? Those would most likely fry both disks. And then there\u2019s always the possibility that your home will flood or burn to the ground, taking both disks with it.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"RAID_LEVEL_0_is_a_Striped_Disk_Array_without_Fault_Tolerance\"><\/span>RAID LEVEL 0 is a Striped Disk Array without Fault Tolerance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Specs and advantages<\/strong><\/p>\n<ul>\n<li>RAID 0 uses a striped disk array where data is broken down into blocks, then each block is written to a separate disk drive<\/li>\n<li>Input \/ Output (I\/O) performance is thus improved by spreading the load across multiple channels and disks<\/li>\n<li>Ultimate performance happens when the data is striped across multiple controllers with only 1 drive per controller<\/li>\n<li>There is no parity overhead<\/li>\n<li>Its design is simple and very easy to implement<\/li>\n<\/ul>\n<p><strong>Why not RAID LEVEL 0<\/strong><\/p>\n<ul>\n<li>It\u2019s not fault-tolerant<\/li>\n<li>If one drive fails, this will result in the loss of all data in that array<\/li>\n<li>If you live and die in a mission critical environment, RAID 0 is not for you.<\/li>\n<\/ul>\n<p><strong>What we recommend you use RAID LEVEL 0 for<\/strong><\/p>\n<ul>\n<li>The Production and Editing of Videos and Images<\/li>\n<li>High bandwidth Applications<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"RAID_LEVEL_1_utilizes_Mirroring_and_Duplexing\"><\/span>RAID LEVEL 1 utilizes Mirroring and Duplexing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Specs and Advantages<\/strong><\/p>\n<ul>\n<li>One Write or two Reads are possible per mirrored pair<\/li>\n<li>It has double the Read transaction rate of single disks and the same Write transaction rate as single disks<\/li>\n<li>In case of a disk failure, it\u2019s one hundred percent redundant.
