As\u00a0data\u00a0and parity are striped across all of the disks, no single\u00a0disk\u00a0creates a\u00a0bottleneck.<\/li>\n<li>Conversely, RAID 10 combines\u00a0disk mirroring\u00a0and\u00a0disk striping\u00a0to protect data. RAID 10\u00a0requires a minimum of four\u00a0disks, and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional,\u00a0data\u00a0can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is no\u00a0parity\u00a0in the striped sets. RAID 10 provides\u00a0redundancy\u00a0and\u00a0performance, and is the best option for\u00a0I\/O-intensive applications. One disadvantage is that only fifty percent of the total raw capacity of the drives is usable due to mirroring.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"HDD\"><\/span>HDD<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Raid 5 is less efficient on normal spinning hard disks (HDD) because it increases the number of random I\/O operations. Writing small amounts of data more frequently results in slower performance than when writing larger amounts of data sequentially.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"SSD\"><\/span>SSD<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Conversely, \u00a0SSDs can write random smaller blocks of data more efficiently. What\u2019s more important though is knowing the total amount of data written to the drive.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Parity\"><\/span>Parity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A\u00a0parity drive\u00a0is a hard\u00a0drive\u00a0used in a RAID array to provide fault tolerance. For example, RAID 5 uses a\u00a0parity drive\u00a0to create a system that is both fault tolerant and, because of data striping, fast. One way to implement a\u00a0parity drive\u00a0in a RAID array is to use the exclusive or, or XOR, function.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Striping\"><\/span>Striping<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Disk striping is the process of dividing a body of\u00a0data\u00a0into\u00a0blocks\u00a0and spreading the data blocks across multiple\u00a0storage\u00a0devices, such as\u00a0hard disks\u00a0or solid-state drives (SSDs). A stripe consists of the data divided across the set of hard disks or SSDs, and a striped unit, or strip, that refers to the data slice on an individual drive.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Writing_hard_amounts_of_data_to_the_array_at_once\"><\/span>Writing hard amounts of data to the array at once<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>With RAID 5, you\u2019re not writing the data five times over \u2013 it\u2019s actually 1.25 times in total with \u00bc to each of four drives and the additional to the fifth drive for parity. This helps improve data recovery.<\/p>\n<p>With RAID 10, all of the data is mirrored, so when using four drives, \u00bd of the available write bandwidth is utilized to store copies of your data.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Efficiency\"><\/span>Efficiency<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>RAID 10 is more efficient in that it\u2019s able to keep the drives active (at a maximum) more so than RAID 5. However, for maximum performance (actual writing speed), RAID 5 is better because less time is used storing information that is redundant.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Workload_variances\"><\/span>Workload variances<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you\u2019re testing efficiency between these two types of RAID configurations, be aware that your results will vary depending on the type of test data you\u2019re utilizing. A single threaded test will produce different results than say, running multiple simultaneous write threads.<\/p>\n<h4><img decoding=\"async\" class=\"aligncenter wp-image-51 size-full\" src=\"https:\/\/www.prolimehost.com\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935.jpg\" alt=\"ProlimeHost RAID Server Solutions\" width=\"400\" height=\"80\" srcset=\"https:\/\/www.prolimehost.com\/blogs\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935.jpg 400w, https:\/\/www.prolimehost.com\/blogs\/wp-content\/uploads\/sites\/4\/2014\/08\/unnamed-e1408122780935-300x60.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/h4>\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"BROUGHT_TO_YOU_BY_PROLIMEHOST\"><\/span>BROUGHT TO YOU BY PROLIMEHOST<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>We\u2019ve been in the web hosting industry for over a decade, helping hundreds of clients succeed in what they do best and that\u2019s running their business.
