The ST225 is designed for single-user desktop systems, local storage in-network or multi-user systems, Or as an add-in upgrade for PCs. The low-power ST225 design is ideal for these applications in either rugged industrial or quiet office environments. The ST225 supports the industry-standard ST412 interface and has the same voltage requirements for ease of integration.<\/p>\n<p style=\"text-align: justify;\">High reliability is assured through the use of Large Scale Integration, a single printed circuit board, mini-monolithic heads, and proven oxide media. Scagate&#8217;s proprietary helical-band rotary-actuator features simplicity and ease of manufacture with excellent thermal stability. A dedicated head shipping zone assures data integrity during shipping and handling. The ST225 offers a low-cost, rugged, and reliable disc drive with an MTBF of 20,000 hours<\/p>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text el_class=&#8221;museum_video&#8221;]<iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/7ttXCDKbhaY\" width=\"600\" height=\"400\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator color=&#8221;white&#8221;][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;753&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;link_image&#8221; el_class=&#8221;museum_item&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1610897631941{border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 0px !important;border-left-width: 0px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;background-color: #000000 !important;}&#8221;] Model: Seagate ST-225 Manufacturer: Seagate Released in: 1986 Capacity: 20MB CMOS type: 2 Specifications Rotational Speed: 3,600 RPM \u00b1 1% Recording Density: 9,827 BPI (Cylinder 614)\u00a0 Flux Density: &hellip; <a href=\"https:\/\/emuseum.ucsc.cmb.ac.lk\/?page_id=750\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;ST-225 (Hard Drive) (1986)&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":753,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"categories":[71],"tags":[],"_links":{"self":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/750"}],"collection":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=750"}],"version-history":[{"count":7,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/750\/revisions"}],"predecessor-version":[{"id":2230,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/750\/revisions\/2230"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/media\/753"}],"wp:attachment":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=750"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=750"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=750"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
