In many cases the investment of replacing hard drives is taken on the assumption that SSDs are generally faster. But it depends on various parameters whether or not this assumption is true for a specific system. It is crucial to know which demands a system has to its disk subsystem in order to design it correctly. It is important to analyze how the devices behave under certain circumstances to ensure they can fulfill one&#8217;s storage needs. Such performance tests are generally difficult to implement because they need to be accurate in terms of setup, test scenario and result reporting.<\/p>\n<p>There are many performance testing tools which do not cope with the previously noted requirements. Due to the lack of automatically generated testing reports it is often difficult to figure out test parameters and the system&#8217;s environment. In this talk we dive into the topics of I\/O performance and discuss I\/Os per second, throughput and latency. We also present the Open Source performance suite TKperf which uses the Flexible I\/O Tester (Fio) in the background. Covering the needs described above it brings performance testing to a next level. TKperf implements the tests specified in the SNIA \u201cSolid State Storage (SSS) Performance Test Specification (PTS) Enterprise v1.0\u201d, fulfilling all of its reporting requirements. We applied the ideas of the specification to test traditional hard disks with TKperf, too.<\/p><\/blockquote>\n<h3>Die Vortragsfolien&nbsp;<a href=\"http:\/\/www.thomas-krenn.com\/de\/wikiDE\/images\/9\/93\/20130523-ssd-and-hdd-performance-testing-with-tkperf.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">stehen hier zum Download<\/a>&nbsp;bereit.<\/h3>\n<p>&nbsp;<\/p>\n<div style=\"background-color: #f2f2f2; padding: 15px; height: auto; vertical-align: middle;\">\n<div style=\"display: inline-block; background-color: #f2f2f2; margin-right: 15px; vertical-align: middle; width: 80px; height: auto;\"><a href=\"https:\/\/www.thomas-krenn.com\/de\/tkmag\/expertentipps\/warum-standard-backupsoftware-noch-immer-sinnvoll-ist\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-5718\" src=\"https:\/\/www.thomas-krenn.com\/de\/tkmag\/wp-content\/uploads\/2013\/08\/TKmag_Logo.png\" alt=\"TKmag_Logo\" width=\"78\" height=\"26\"><\/a><\/div>\n<div style=\"display: inline-block; background-color: #000000; vertical-align: middle; width: 1px; height: 27px;\"><\/div>\n<div style=\"display: inline-block; background-color: #f2f2f2; margin-left: 15px; vertical-align: middle; width: 80%;\">Testergebnisse von TKperf finden Sie im Artikel \u201eUnsere TKperf Performance-Ergebnisse in der \u00dcbersicht&#8220;.<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Vortrag vom Linux-Tag 2013&nbsp;von&nbsp;Georg Sch\u00f6nberger.
