Conclusion<\/h2>\n
Although EBS Provisioned IOPS does appear to almost always guarantee consistency in throughput, it also prevents you from attaining the maximum available speeds available through bursting.<\/p>\n
Write performance on EBS is considerably slower than read performance. \u00a0If you perform a lot of writes, Provisioned IOPS can really help.<\/p>\n
If you are going to purchase a provisioned IOPS volume, provision 3000+ IOPS, or you’re likely to get better performance on average with EBS standard.<\/p>\n
Unfortunately EBS Provisioned IOPS is not a magic bullet for increased IO performance, only consistency. \u00a0No matter which type of EBS volume you choose, it’s going to be slow.<\/p>\n","protected":false},"excerpt":{"rendered":"
I recently set up a provisioned IOPS EBS volume on Amazon EC2. \u00a0I decided to run CrystalDiskMark against it to see how it compared to a standard EBS volume in terms of performance. \u00a0I wanted to know if provisioned IOPS is worth the extra money that you pay for it. \u00a0Here are the results: EBS […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[302,304,303],"tags":[306,307,310,309,324,323,305,308],"class_list":["post-250","post","type-post","status-publish","format-standard","hentry","category-amazon-web-services","category-ebs","category-ec2","tag-amazon","tag-aws","tag-benchmark","tag-crystaldiskmark","tag-ebs","tag-ec2","tag-provisioned-iops","tag-windows"],"_links":{"self":[{"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/posts\/250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/comments?post=250"}],"version-history":[{"count":3,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/posts\/250\/revisions"}],"predecessor-version":[{"id":255,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/posts\/250\/revisions\/255"}],"wp:attachment":[{"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/media?parent=250"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/categories?post=250"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.visigo.com\/chriscoulson\/wp-json\/wp\/v2\/tags?post=250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
